The GPS system is operated by the United States government, which is solely responsible for
its accuracy and maintenance. The system is subject to changes which could affect the accuracy and
performance of all GPS equipment. Although the GARMIN GPSMAP 182/232 is a precision electronic
NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted and, therefore, become
unsafe.

The electronic chart is an aid to navigation and is designed to facilitate the use of authorized
government charts, not replace them. Only offi cial government charts and notices to mariners contain all
information needed for safe navigation – and, as always, the user is responsible for their prudent use.

Use the GPSMAP 182/232 at your own risk. To reduce the risk of unsafe operation, carefully
review and understand all aspects of this Owner’s Manual—and thoroughly practice operation using the
simulator mode prior to actual use. When in actual use, carefully compare indications from the GPSMAP
182/232 to all available navigation sources, including the information from other NAVAIDs, visual
sightings, charts, etc. For safety, always resolve any discrepancies before continuing navigation.

The GPSMAP 182/232 complies with Part 15 of the FCC interference limits for Class B digital

How To Select Options and Enter Data

Before moving ahead into the features of the GPSMAP 182/232, you will need to learn basic
operations. You can select and activate options and enter data to customize the GPSMAP 182/232 to fi t
your requirements. You can use the ENTER/MARK key and ARROW KEYPAD to select options, enter
names and numbers in data fi elds, and activate your selections.

To select and activate an optional feature:

1. With any page displayed, press the MENU key to pop-up the options menu. The options menu will
display a list of optional features which are specifi c for that particular page. To select any feature on
the list of options requires movement of the cursor, which is identifi ed as highlighting, selecting or
choosing an item in a list or a fi eld (box) on a page.

2. Use the ARROW KEYPAD to move the cursor (highlight) up and down a list or up, down, and
sideways on menus.

3. Once you have moved to the selection desired, press the ENTER/MARK key to either activate the
feature or the MENU key to pop-up a sub-menu or list of yet more feature options. Just repeat this
process to select an option from the list or press the QUIT key to return to the previous setting.

The QUIT key will move backwards through these steps or when pressed, back to the main page

you started on.

To select and activate a function button:

1. When moving about a page with function buttons, like the ‘New Map Waypoint’ page, you will
observe functions such as ‘Show Map’, ‘Delete’ and ’OK’. To activate the function, highlight the
desired button and press the ENTER/MARK key.

Pop-up list of options for a highlighted

fi eld.

Naming a waypoint or placing any sort of data that has not been predefi ned requires the use of

both the ARROW KEYPAD and the ENTER/MARK key.

To enter a name or number in a data fi eld:

1. Once you have accessed a page with programmable data fi elds (i.e. ‘ Waypoint Edit’) you can use
the ARROW KEYPAD to move the cursor (Highlight) to fi elds on the page. Use the UP/DOWN
arrows to move up or down and the LEFT/RIGHT arrows to move sideways.

2. Pressing the ENTER/MARK key with the fi eld highlighted begins the process for entering data in
the form of alphanumeric characters.

3. Use the ARROW KEYPAD UP/DOWN arrows to cycle through numbers 0 to 9, plus/minus symbols,
blank space, and the alphabet. Pressing and releasing the keypad moves you character by character
through the list. Pressing and holding the keypad moves you rapidly through the list.

4. Use the ARROW KEYPAD LEFT/RIGHT arrows to move to the next character on the line or
backwards to edit characters. If there are more than two lines of data, keep pressing to the RIGHT
to drop down to the next line.

5. When data entry is completed press ENTER/MARK to accept data, then move to the next
programmable fi eld. Not all data fi elds are programmable, like the date and time. When moving
about a page with these type of fi elds, the cursor will skip over them.

Every fi eld and button on this page
can be programmed or activated.

• A waypoint symbol can be selected
from a list of symbols.

• A comment can be added.

• The coordinates can be changed.

• The waypoint can be renamed.

• A depth can be entered.

• Option buttons can be activated.

The GPSMAP 182/232’s advanced keypad system is designed to allow for fast, convenient selection
of navigation options and data entry. The Getting Started Tour will introduce you to the keypad and
provide a ‘hands-on’ lesson in using the GPSMAP 182/232. We strongly encourage you to take the
Getting Started tour before using your unit for actual navigation.

The GPSMAP 182/232 Quick Reference Guide contains helpful tips on using the unit and perform­ing various navigation tasks. It’s a good idea to keep the Quick Reference Guide nearby whenever you’re
operating your new GPSMAP 182/232.

Initializing the Receiver

The fi rst time you power up your new GPSMAP 182/232, the receiver must be given an opportu­nity to collect satellite data and establish its present position. To ensure proper initialization, the
GPSMAP 182/232 is shipped from the factory in AutoLocate mode, which will allow the receiver to
“fi nd itself” anywhere in the world. To speed up the initialization process, we recommend using the
graphic initialization process described on the next page, which will usually provide a position fi x
within a few minutes.

Before you initialize, make sure the GPSMAP 182/232 unit and antenna have been correctly
installed on your vessel according to the instructions in Appendix G. The antenna needs to be in a
location with a clear and unobstructed view of the sky to receive satellite signals.

To turn the GPSMAP 182/232 on:

1. Press and hold the POWER key until the power tone sounds and the display comes on, then
release the POWER key.

A warning page will appear, asking you to read and acknowledge important information regarding

the proper use of the unit.

To acknowledge the warning:

1. After reading the warning, press the ENTER/MARK key if you agree.

To graphically initialize the GPSMAP 182/232:

1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until
the ‘GPS’ tab is highlighted, then press the MENU key once.

2. Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER/MARK to initialize
the receiver from the map. The Initialize Position Page will appear, prompting you to select your
approximate location with the map cursor.

3. Use the ARROW KEYPAD to move the map cursor and point to your approximate location within
200 miles. If you have diffi culty identifying your position, press and release the IN key to see the
next lower map scale.

4. Once you have determined your approximate location on the map, press the ENTER/MARK key.

This does not “calibrate” the unit in any way, but rather helps to speed up the initial

I

satellite acquisition. If the unit displays “Ready (2D) or (3D )” during this process, it is
not necessary to initialize the unit.

The GPSMAP 182/232 will now begin searching for the appropriate satellites for your region and
should acquire a fi x within a few minutes. When viewing the ‘GPS’ tab on the Main Menu, a signal
strength bar for each satellite in view will appear on the bottom of the page, with the appropriate
satellite number under each bar. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Hollow signal strength bars— the receiver has found the indicated satellite(s) and is collecting data.

• Solid signal strength bars— the receiver has collected the necessary data and the satellite(s) are
ready for use.

Once the receiver has collected information from at least three satellites, the top of the screen will

display either “Ready (2D or 3D)”, and the GPSMAP 182/232 is ready for use.

Initializing the Receiver

Point to your approxi­mate location and press
ENTER/MARK.

A satellite’s strength bars
will turn black when it’s

GPSMAP 182/232 Getting Started Tour

The GARMIN GPSMAP 182/232 is a powerful electronic navigation system that provides detailed
map coverage and convenient control of many advanced features right from the screen display. This
tour is designed to take you through the basic pages and functions of the system using the simulator
mode. Once you’re familiar with the main pages and functions of the unit, refer to the reference section
for instructions on performing specifi c tasks and functions.

The Getting Started Tour assumes that the receiver has been properly installed and initialized,
and you have not changed any of the default unit settings. If you have changed any settings (position
formats, units of measure, etc.), the descriptions and pictures in the tour may not match your
confi guration.

To turn the GPSMAP 182/232 on:

1. Press and hold the POWER key until the power tone sounds, then release the POWER key. The
Warning Page will appear while the unit conducts a self-test.

2. Once the self-test is complete, press the ENTER/MARK key, if you agree, to acknowledge the
warning.

The GPS Information Page will appear as the receiver begins acquiring satellites. From this or any

other page, you may also adjust the screen contrast and backlighting.

To adjust the screen contrast:

1. Press POWER and the Light and Contrast window will appear.

2. To decrease or increase the screen contrast, press left or right on the ARROW KEYPAD.

3. Press the ENTER/MARK key to fi nish.

The GPSMAP 182/232’s adjustable screen backlighting is controlled with the POWER key, and
may be adjusted at any time from any page. The backlight can cycle through off, user-defi ned, and
maximum backlight levels by repeatedly pressing the POWER key.

To turn on and adjust the backlighting:

1. Press POWER and the Light and Contrast window will appear.

2. Press POWER again and the user-defi ned level of backlighting will activate. You may adjust this
level by pressing UP or DOWN on the ARROW KEYPAD. If you press POWER one more time, the
backlighting will be at the maximum setting.

3. Press ENTER/MARK or QUIT when done.

The backlight will now cycle through off, the user-defi ned, and maximum backlight levels by

repeatedly pressing the POWER key.

Each page of the GPSMAP 182/232’s system also features an options page, which gives you access
to other functions and features that relate to the specifi c page you are viewing. To get a feel for how the
options pages work, let’s put the GPSMAP 182/232 into simulator mode.

To place the GPSMAP 182/232 in simulator mode:

1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until
the ‘GPS’ tab is highlighted, then press the MENU key once.

2. Use the UP or DOWN arrow of the ARROW KEYPAD to highlight the ‘Start Simulator’ option and
press ENTER/MARK. Choose ‘No’ to the retail demonstration and press the ENTER/MARK key.

3. Press the ENTER/MARK key to confi rm the ‘Running Simulator’ message that appears at the
bottom of the display. ‘Simulating’ will appear at the top of the Main pages.

Once the simulator has been started, an ‘S’ will appear in the lower left corner of every page. Now

you’re ready to continue the rest of the simulated tour. Keep in mind that the GPSMAP 182/232

does not track satellites in simulator mode, and this mode should never be used for actual
navigation. All the waypoint and route planning done in simulator mode will still be retained in

memory for future use.

Map Page

The Map Page is one of fi ve main pages used in the GPSMAP 182/232’s system. The fi ve main pages
are the Map Page, Compass Page, Numbers Page, Highway Page, and Active Route Page. All fi ve pages
are linked together in a simple chain, which allows you to scroll through the pages in either direction
using the PAG E and QUIT keys.

The GPSMAP 182/232’s Map Page combines digital chartplotting with a user-selectable display of
navigation data and a built-in worldwide database. It will also be the page you use most to create
and edit waypoints and routes. Before we take off on our practice route, let’s take a brief look at its
various features and displays.

The map display shows your “boat” as a triangle marker on an electronically generated chart.
Geographic names, roads, markers and buoys that are provided by the optional BlueChart or MapSource
data are also shown. It also displays your track, routes and nearby waypoints. An on-screen cursor
lets you pan to other map areas, determine the range and bearing to a position, and perform various
waypoint and route functions.

The data window, located at the top of the page, provides a user-selectable display of various
navigation data, including speed over ground, distance to the next navigation point, compass ribbon and
current position coordinates. The current map scale setting is located at the bottom right of the page.

Using the Map Cursor

Working from the Map Page is a simple process that centers around the use of the cursor.

Controlled by the ARROW KEYPAD, the cursor is an important tool that can be used to pan to
other map locations, mark and edit waypoints and routes, and review position data of on-screen map
items and waypoints.

To get a feel for using the Map Page and using the cursor, try the following exercise:

1. Use the IN/OUT keys to set the map scale to the 50 nm setting. Your boat should be near the center
of the map, at the receiver’s last known position. (If your boat isn’t where it should be, make sure
that you have initialized the receiver and acquired a position as described on pages 1-2.)

2. Use the ARROW KEYPAD to move the cursor. Notice how another data fi eld appears, showing
the bearing and distance from your boat to the cursor, along with the latitude/longitude of the
cursor.

3. Press the QUIT key to remove the cursor and re-center your boat on the map display.

As you become more familiar with the cursor, you’ll see that the map display actively scrolls or
‘pans’, letting you explore areas around the world and create waypoints and routes. Wherever you
move the cursor, you’ll always be just one QUIT keystroke away from returning the map to your
present position.

Now that you’ve seen how the Map Page can be used to monitor your present location, let’s take a
minute to learn how to mark and store your present position as a waypoint. (Since you’re in simulator
mode, the present position displayed will be the last position calculated by the receiver, which should
be the spot where you’ve initialized the unit.) This will also give you an opportunity to see how the
GPSMAP 182/232’s keypad and ENTER/MARK key are used for data entry and changing the waypoint
name and symbol.

Marking Waypoints

You can choose from a list
of useful symbols.
There are two Diver Down
waypoint symbols to select
from: the International ver­sion and the U.S. version.

10

Press ENTER/MARK
after entering the name

To mark your present position:

1. Hold down the ENTER/MARK key until the ‘New Waypoint’ window appears then release the
key. The window will show a default three-digit waypoint name/number (001), symbol (dot), and
position. You can leave the name as the auto-assigned number, but for this exercise, lets change
the name to ‘DOCK’.

2. Use the ARROW KEYPAD to highlight the waypoint name fi eld (001) and press ENTER/MARK.
You will see that just the fi rst ‘0’ is now highlighted.

3. Press LEFT on the ARROW KEYPAD to clear the name fi eld.

4. Press UP or DOWN on of the ARROW KEYPAD until the letter ‘D’ appears, and then press RIGHT
to go to the next space to the right, then UP or DOWN again until ‘O’ appears. Repeat this until you
have entered the name ‘DOCK’. If you make a mistake and select an incorrect character, simply press
LEFT on the ARROW KEYPAD to backspace the cursor and then UP or DOWN to correct the entry.
(If you accidentally press ENTER/MARK before you are done, simply press ENTER/MARK again
and move the highlight to where you left off.)

5. After you have entered all the letters, press ENTER/MARK to confi rm the name.

6. To access the waypoint symbol page, highlight the waypoint symbol fi eld which is to the left of the
waypoint’s name and press ENTER/MARK. Note: The default symbol is a dot.

7. You will see an alphabetical list of available waypoint symbols to choose from. Press the ARROW
KEYPAD UP or DOWN until you highlight the ‘ANCHOR’ symbol. You will see a scroll bar on the
right of the window indicating your current position on the entire list of symbols.

8. Press ENTER/MARK to confi rm the ‘ANCHOR’ symbol.

9. Highlight ‘OK’ at the bottom of the window and press ENTER/MARK again to confi rm the ‘OK’
prompt and save the waypoint.

The waypoint is now stored in memory. Note that waypoints may also be created graphically from
the map display or by manually entering position coordinates. Each of these techniques is described in
the reference section of the manual and/or on your GPSMAP 182/232 Quick Reference Guide.

Going to a Destination

GPS is all about marking positions as waypoints and navigating to them using the receiver’s steering
guidance and map displays. We’ve already seen how to use the ENTER/MARK key to store our present
position, so it’s time to move on to the fun part—going to a destination.

The NAV key, located on the keypad above the QUIT key, is the primary tool used to select a
destination waypoint, TracBack, or a route to navigate. The NAV key can be used in two primary
ways:

• Pressing NAV once displays a list of options from which you can select ‘Go To Point’, ‘Follow Route’,

‘Follow Track’, or ‘Stop Navigation’.

• Highlighting an on-screen waypoint or map item as a destination directly from the Map Page and
pressing NAV allows you to graphically select points to “Go To”.

For our simulated trip, you’re going to select a pre-programmed tour route using the fi rst method.
This will also show how the MENU key is used throughout the GPSMAP 182/232 system to provide
tab style options and functions. Let’s start by changing the position to where the practice route is
located.

To change the GPSMAP 182/232 position in simulator mode:

1. Press the MENU key twice to display the list of Main Menu tab items.

2. Use the UP or DOWN arrow of the ARROW KEYPAD to highlight the ‘Systm’ tab.

3. Highlight ‘Set Position’ in the simulator setup window and press ENTER/MARK.

4. From the Initialize Position page, press the MENU key. You will see ‘Enter As Text’ highlighted,
then press ENTER/MARK.

5. On the Enter Position window, press ENTER/MARK then use the ARROW KEYPAD to enter
N34°56.800’, W076°24.066’ and press ENTER/MARK when done, then press QUIT to return
to the Map Page.

To activate the practice route stored in memory for navigation:

1. Press NAV. The option list page will appear. (If we were selecting a single waypoint to navigate
to rather than a route, we could highlight the waypoint on the map, press NAV and then press
ENTER/MARK.)

2. Use the ARROW KEYPAD to highlight the ‘Follow Route’ option. Press ENTER/MARK to confi rm.

3. The Select Route page will appear, with the ‘GPSMAP TOUR’ route highlighted.

4. Press ENTER/MARK then highlight ‘Activate’ and press ENTER/MARK again.

To zoom in to a closer map scale:

1. Repeatedly press the IN key until you select the 3 nm scale.

You may also hold the IN or OUT keys down to quickly scroll through the map scales. The
Map Page should now display fi ve waypoints chained together in a simple route, with your boat at
the fi rst route waypoint.

A data fi eld at the top of the page will now display the speed, distance to the second route
waypoint, your position coordinates and a compass ribbon which shows you which way to go. To get
started, let’s enter a speed for our vessel, which we can do from the Main Menu Page.

To enter a boat speed:

1. Press the MENU key twice to display the Main Menu Page.

2. Use the ARROW KEYPAD to highlight the ‘Systm’ tab, then press RIGHT then DOWN until the fi eld
below the word ‘Speed’ is highlighted and press ENTER/MARK.

3. Use the ARROW KEYPAD to enter a speed of 60 knots.

4. Press ENTER/MARK to fi nish, and QUIT until you return to the Map Page.

Once a speed has been entered, you’ll notice that the map will automatically begin to move slowly,
keeping your boat centered on the display. The direction of movement, also called ‘track’, will be
controlled by the simulator.

You’ll now have a clearer picture of the route you are navigating. Keep in mind that whenever you
do exceed the usable range of the built-in database or the optional MapSource or BlueChart data in use,
the range fi eld will display ‘OVERZOOM’ to indicate that you should exercise extreme caution using the
map data. Press the IN key to zoom into the 2 nm scale. Now that you’ve zoomed in a little closer to
your route, you can pan ahead of your vessel with the cursor to review map items and create on-screen
waypoints. Try moving the cursor to highlight the ‘TOUR3’ waypoint— just use the ARROW KEYPAD
to move the cursor as close as possible to the waypoint. (To move the cursor in small increments, try
a series of short key presses.)

Once the cursor is over the TOUR3 waypoint, you’ll notice that the waypoint symbol and name will
become highlighted. The data fi eld at the top of the page will display the waypoint name, the range and
bearing from your present position, and the coordinates for the waypoint.

To review the waypoint page for a selected waypoint:

1. Press the ENTER/MARK key.

2. To return to the Map Page, press ENTER/MARK again or press QUIT.

The waypoint will ‘highlight’
when the cursor is moved
over it.

The cursor can also be used to create new waypoints right from the map display.

To create a new waypoint using the cursor:

1. Use the ARROW KEYPAD to move the cursor as close as possible to the following position:
N35º 02.914; W 076º 26.152’ (Use the data window to verify the cursor position.)

2. Press and release the ENTER/MARK key to capture the cursor position. Do not hold the button
down, as doing so will mark your present position, not the map position.

3. Use the ARROW KEYPAD to highlight the waypoint symbol fi eld to the left of the waypoint
name/number.

4. Press ENTER/MARK to access the symbol page.

5. Press UP or DOWN on the ARROW KEYPAD to select the ‘Shipwreck’ symbol and press
ENTER/MARK to confi rm.

6. Highlight ‘OK’ at the bottom and ENTER/MARK again to fi nish.

Now that we’re navigating to an actual destination, let’s move on to the GPSMAP 182/232

navigation pages by pressing the PAGE key.

The Compass Page provides graphic steering guidance to a destination waypoint, with an emphasis
on the bearing to your destination and current direction of travel. The middle of the page features a
rotating ‘compass ring’ that shows your course over ground (track) while you’re moving, and a bearing
pointer that indicates the direction of the destination (bearing) relative to the course over ground.
The compass ring and pointer arrow work independently to show—at a glance—the direction of your
movement and the direction to your destination. For instance, if the arrow points up, you are going
directly to the waypoint. If the arrow points any direction other than up, turn toward the arrow until it
points up—then continue in that direction.

The current speed, distance to the next waypoint, turn angle and current position are displayed
at the top of the screen. This page provides better steering guidance when travelling at slower speeds
and/or when making frequent directional changes. When you are not navigating to a waypoint, the
compass will show your direction of travel as you move but the arrow will not appear.

Press PAGE to see the next page appearing in the main sequence, the Numbers Page. The
Numbers Page allows for precision navigation to 1 degree of steerage. The default page will display 3
large numbers fi elds. You may customize the Numbers Page to display the size and number of fi elds
along with the type data you wish to see. (See pages 22-23 for changing the types of data.)

To split the data fi elds:

1. Press MENU, then press ENTER/MARK. Highlight the ‘SPEED’ data fi eld and press MENU.

2. Highlight ‘Split Numbers’, then press ENTER/MARK. You will now see four new data fi elds. Press
QUIT when done.

3. To return to the original confi guration, repeat the above steps, but instead of ‘Split Number’, select
either ‘Merge Numbers’ or ‘Defaults’. Press QUIT when done.

Let’s move on to the Highway Page by pressing the PAG E key.

The GPSMAP 182/232’s Highway Page also provides graphic steering guidance to a destination
waypoint, placing greater emphasis on the straight-line desired course and the distance and direction
you are off course. As you head toward your destination, the middle of the screen provides visual
guidance to your waypoint on a moving graphic “highway.” Your present position is at the bottom
center of the highway display. The line down the middle of the highway represents your desired course.
As you navigate toward a waypoint, the highway will actually move—indicating the direction you’re off
course. To stay on course, simply steer toward the center of the highway or “keep it on the road”. The
four default data fi elds at the top of the page indicate ‘Speed’ and ‘Distance To Next’ point, along with
‘To Course’ which shows the bearing to get you back on course and ‘Time To Next’ point. Additionally,
a compass ribbon is displayed to show your current heading along with a dark, vertical bar which will
indicate the direct bearing to the navigation point. When the dark, vertical indicator (or arrow) lines
up with the lighter gray bar in the middle, you are heading directly to the navigation point. Use the
Highway Page as your primary navigation page (in lieu of the Compass Page) when your main concern
is following a defi ned course.

Whenever the GPSMAP 182/232 is in simulator mode, you can also adjust your speed and course
from the Highway Page using the ARROW KEYPAD. As you head toward each waypoint in the tour
route, try adjusting your boat speed and course to get a feel for how the highway works.

To adjust the simulated boat speed/heading from the Highway Page:

1. Press the UP arrow of the ARROW KEYPAD to increase the speed in 10 knot/kph/mph increments.
Press the DOWN arrow to decrease the speed in the same increments. Press the LEFT and RIGHT
arrows of the ARROW KEYPAD to steer the boat.

Notice that as you get off course, the highway will move to give you graphic guidance to get
back on course. You can zoom in or out on the Highway display for a smaller or larger view. Five
available settings range from 1X to 16X, with a default setting of 8X. The current scale will appear
in the bottom right of the display.

To zoom in or out on the highway display:

1. Press either the IN or OUT key to increase or decrease the zoom scale.

see page 48.

As you’ve seen, the primary pages provide map and navigation information. The tour’s last page is the
Main Menu page, which allows access to the GPSMAP 182/232’s waypoint, route and planning functions,
as well as various operational and navigation setup features, and celestial and tide data.

The Main Menu is available from any page, and is accessed through the MENU key.

To access the main menu page:

1. Press the MENU key twice.

The Main Menu page lists 15 menu ‘tabs’ that are divided into categories by function. You can
view a particular menu by simply highlighting the desired tab, which will then show any secondary
submenu tabs and options for that tab.

To get a basic feel for how the Main Menu page works, let’s delete the two waypoints you created
during the simulated tour. This will ensure that you have a clean slate once you start navigating in
your home waters.

To select the Points (Waypoint) submenu tab:

1. Use the ARROW KEYPAD to highlight the ‘Points’ menu tab. You will see a list of stored waypoints
appear to the right of the Main Menu list.

2. Press to the right one time on the ARROW KEYPAD and you will see the ‘User’ tab highlighted.

3. Press down on the ARROW KEYPAD until waypoint 001 with the shipwreck symbol is highlighted.

The GPSMAP 182/232’s Map Page provides a comprehensive display of electronic cartography,
plotting and navigational data. When using the unit with the optional BlueChart data or MapSource
software, the map display shows your boat on a digital chart, complete with geographic names, map
items, navaids and a host of other chart features. It also plots your track and displays any routes and
waypoints you create. An on-screen cursor lets you pan and scroll to other map areas, determine the
distance and bearing to a position, and perform various route and waypoint functions.

When the cursor is active, an additional data window will appear below the data fi elds to indicate
the position, range and bearing to the cursor or a selected waypoint or map item. The map scale
displays at the bottom right of the page.

The (ZOOM)IN and (ZOOM)OUT keys, combined with the ARROW KEYPAD, let you select
zoom ranges and move the cursor. Two basic map operating modes, position mode and cursor mode,
determine what cartography is shown on the map display. Position mode pans the cartography to keep
the present position marker within the display area, while cursor mode pans the cartography to keep
the cursor within the display area.

The GPSMAP system will always power up in the position mode, with your vessel centered on
the map display.

• When suffi cient map coverage is not available to keep the boat centered, the boat icon will move
toward the edge of the display.

When the ARROW KEYPAD is pressed, the GPSMAP 182/232 will enter cursor mode. In cursor

mode:

• The cursor can be moved over the map display using the ARROW KEYPAD.

• Whenever the cursor reaches the edge of the display, the map will scroll forward under the cursor.
Keep in mind that the boat icon will move with the map scrolling and may go off the display
screen (you may not be able to see your present position).

• When the cursor is stationary, a fi xed coordinate position will appear in the position fi eld. Note that
the distance and bearing will change as the boat’s position changes.

• Whenever you zoom in cursor mode, the cursor will be centered on screen.

• To return to position mode, press the QUIT key.

When the cursor reaches the edge of the map, the unit may pause as it loads new

Map Page Cursor

Using the Cursor

The cursor allows you to pan away from your present position and scroll to other map areas around
the world (even outside of your current detail coverage). As you pan past the edge of the current map
display, the screen will actively scroll forward to provide continuous map coverage. You will see an
hourglass symbol by the pointer while the unit is busy drawing new map detail.

To move the cursor:

1. Press the ARROW KEYPAD to move the cursor in an up, down, left or right direction.

As you move the cursor, the distance and bearing from your present position to the cursor will be
displayed in the data window, along with the cursor’s position coordinates. Keep in mind that when
the cursor is stationary, the distance and bearing from your present position will change as your boat
moves. The cursor may also be used to ‘snap’ to on-screen waypoints and map items, allowing you to
review a selected position directly from the map display.

To select an on-screen waypoint or map item with the cursor:

1. Use the ARROW KEYPAD to move the cursor to the desired waypoint or map item (if there are
several waypoints grouped closely together, zoom in closer for a better view).

2. When a waypoint or map item is selected, it will become highlighted on screen, with the name and
position displayed. Press ENTER/MARK to show details of the map item. When using BlueChart or
MapSource data, additional information tabs will appear. Use the ARROW KEYPAD to highlight

The GPSMAP 182/232’s system has a built-in worldwide database to 20 mi, with more detailed
coverage available through the use of the optional BlueChart or MapSource data. The GPSMAP 182/232
will display cartography as long as there is chart information available for the range you’ve selected.
Map coverage will conform to the following conditions:

• When the selected zoom range is covered by either the internal database, BlueChart, or MapSource
data, cartography will be displayed.

• When the selected zoom range is covered by both the internal database and BlueChart/MapSource
data, cartography will be displayed using the data with the best resolution.

• When the selected zoom range exceeds the resolution of the data in use, overzoom cartography will
be displayed and an ‘overzoom’ warning will appear below the scale fi eld.

Map Page Options

Many features of the GPSMAP 182/232 are menu driven. Each of the main pages have an options

Compass Page

The GPSMAP 182/232 features two different navigation pages: Compass and Highway. Whenever a
NAV, Follow Track (TracBack) or Follow Route have been activated, the GPSMAP 182/232’s Compass
Page will guide you to your destination with digital readouts and a graphic compass display, which
includes a bearing pointer. Use this page (instead of the Highway Page) when travelling at slower
speeds, when making frequent directional changes, or where straight-line navigation is not possible due
to obstructions or terrain. The middle of the page features a rotating ‘compass ring’ that shows your
course over ground (track) while you’re moving. Your present course over ground is indicated at the top
of the compass ring. A bearing pointer arrow, in the middle of the compass ring, and a bearing ‘bug’
indicator on the outside of the compass ring, indicate the direction of the destination (bearing) relative
to the course over ground. The compass ring and pointer arrow work independently to show—at a
glance—the direction of your movement and the direction to your destination. For instance, if the
arrow points up, you are going directly to the waypoint. If the arrow points any direction other than up,

turn toward the arrow until it points up, then continue in that direction.

The bearing pointer, bearing bug and/or compass ring may point in various directions

I

when you are stationary or at very low speeds. Once you start moving, the pointer
will be correct.

Highway Page

Whenever a Go To, TracBack or route has been activated, the GPSMAP 182/232’s Highway Page
will provide digital and graphic steering guidance to the destination with the Navigation Page. The
top half of the Highway Page features user-selectable data fi elds that display useful navigation data.
Additionally, a compass ribbon is displayed to show your current heading along with a dark, vertical
bar which will indicate the bearing to your course. To stay on course, steer towards the dark, vertical
indicator (or arrows) until it lines up with the lighter gray bar in the middle. The bottom section of the
screen provides visual guidance to the waypoint on a graphic highway display. The line down the center
of the highway represents your desired track line.

As you head toward your destination, the highway perspective moves to indicate your progress to
the waypoint and which direction you should steer to stay on course. If you are navigating a route, the
Highway Page shows each route waypoint in sequence connected by a black “road” with a white line
down the middle, which is your desired track line. Nearby waypoints not in the active route can also
be displayed. The highway perspective scale may also be zoomed in or out to display a larger or smaller
view of the highway. Five settings are available from 1X to 16X, with a default setting of 8X.

To change the highway perspective scale:

1. Press the IN or OUT key to select the desired setting.

The GPSMAP 182/232’s Highway options page allows you to defi ne the data fi elds and select which

Creating and Using Waypoints

The GARMIN GPSMAP 182/232 stores up to 3000 alphanumeric waypoints with a user-defi ned
icon, comments and depth available for each waypoint. Waypoints can be created using two basic
methods:

• ENTER/MARK key– used primarily for marking your present position, the ENTER/MARK key also

provides options that allow you to select a map position or map item from the map display. You may
also enter a new waypoint’s position coordinates manually (from a chart, etc.).

• Graphically– allows you to defi ne a new waypoint position from the map display using the ARROW
KEYPAD.

ENTER/MARK Key

The GARMIN GPSMAP 182/232’s ENTER/MARK key lets you quickly capture your present
position— or cursor or map item position— in order to create a new waypoint. You must have a
valid position (2D or 3D) fi x to mark your present position. This can be determined by looking at the
GPS tab on the Main Menu. When you move the cursor over a map item, you will see a highlighted
description of that item. You may also use this option to manually enter waypoint coordinates.

To mark your present position:

1. Press and hold the ENTER/MARK key until the ‘New Waypoint’ window appears then release it.
You will see a default three-digit name and symbol for the new waypoint.

2. To accept the waypoint with the default name and symbol, press ENTER/MARK to confi rm the
highlighted ‘OK’ prompt.

3. To enter a different name, highlight the name fi eld and press the ENTER/MARK key, then use the
ARROW KEYPAD to enter the new letter/numbers and press ENTER/MARK when done. Note: You
may use up to 10 alphanumeric characters for the name.

4. To enter a different symbol, highlight the symbol fi eld to the left of the name and press the

ENTER/MARK key, then use the ARROW KEYPAD to highlight the new symbol and press
ENTER/MARK.

5. To enter optional comments or a depth, highlight the “Comments” or “Depth” fi eld to the right
of the position coordinates and press the ENTER/MARK key, then use the ARROW KEYPAD to
enter a value and press ENTER/MARK.

6. To manually enter a set of coordinates, highlight the coordinates and press the ENTER/MARK
key, then use the ARROW KEYPAD to enter the new coordinates and press ENTER/MARK when
done.

7. When done, use the ARROW KEYPAD to highlight the ‘OK’ prompt and press ENTER/MARK to
save the waypoint into memory.

Creating Waypoints

Creating Waypoints Graphically

Waypoints may also be quickly created from the map display, which allows you to ‘point and shoot’
at any map position to create a new waypoint. To mark a map item, select the desired map item with
the cursor. When selecting a map item, the option ‘Create Wpt’ will appear in addition to a description
of that point and its distance and bearing from your current position.

To create a new waypoint graphically:

1. Use the ARROW KEYPAD to move the cursor to the desired map position. If you want to create the
new waypoint at an on-screen map item, highlight the map item on the map display.

2. Press and release the ENTER/MARK key to capture the cursor position. Do not hold the button
down, as doing so will mark your present position, not the map position.

If you are not using a map item to create a waypoint, go to step 4.

3. Highlight ‘Create Wpt’ or ‘OK’ and press the ENTER/MARK key.

4. To accept the waypoint with the default name and symbol, press ENTER/MARK.

5. To change the name, symbol or add a comment or depth, highlight the appropriate fi eld and press
ENTER/MARK. Make your changes and press ENTER/MARK when done.

6. After entering and confi rming your changes, move the fi eld highlight back to the ‘OK’ prompt and
press ENTER/MARK.

Selecting a ‘Go To’ Graphically

A graphical ‘Go To’ may be used to select one of three items from the map display: an existing
waypoint, an on-screen map item (roads, rivers, cities, navaids, etc.), or a new map point (non-map
item). If you are selecting a map item as the ‘Go To’ destination, the GPSMAP 182/232 will automatically
use the name of the map item, but the point will not be stored in the waypoint list. See page 31 for

creating waypoints using map items. If you are selecting a new map point (non-map item) as the ‘Go
To’ destination, the GPSMAP 182/232 will automatically create or move a waypoint named ‘MAP’ at
the cursor position.

To activate an existing waypoint or map item as a ‘Go To’ from the map display:

1. Use the ARROW KEYPAD to highlight the waypoint or map item on screen and press NAV.

2. You will see ‘Go To <waypoint name>’, then press ENTER/MARK. You may also highlight the
waypoint or map item, press ENTER/MARK, highlight ‘Go To’ from options at the bottom of the
window and press ENTER/MARK.

To activate a new map point (non-map item) as a ‘Go To’ from the map display:

1. Use the ARROW KEYPAD to move the arrow cursor to the desired position.

2. Press NAV, you will see ‘Go To MAP Point’ highlighted, then press ENTER/MARK.

TracBack Navigation (Follow Track)

The second method of navigating to a destination is by using the TracBack or Follow Track feature.
The TracBack function allows you to retrace your path using the track log automatically stored in the
receiver’s memory, which will eliminate the need to store waypoints along the way. TracBack routes are
created by reducing your track log into a route of up to 50 turns and activating an inverted route along
those points. Once activated, a TracBack route will lead you back to the oldest stored track log point, so
it’s a good idea to clear the existing track log before you start your current trip.

To clear the track log and defi ne a starting point for a TracBack route:

1. Press the MENU key twice to display the Main Menu page.

2. Using the ARROW KEYPAD, highlight the ‘Track’ tab, then highlight the ‘Active’ tab to the right.

3. Use the ARROW KEYPAD to select the ‘Erase’ option and press ENTER/MARK.

4. Highlight the ‘OK’ fi eld and press ENTER/MARK.

You must fi rst save the track log before you can use the ‘Follow Track’ feature. The Save feature
allows you to store up to 15 track logs from certain times and dates.

To save a track log:

1. From the Main Menu, use the ARROW KEYPAD to highlight the ‘Track’ tab, then highlight the
‘Active’ tab to the right.

2. Use the ARROW KEYPAD to select the ‘Save’ option and press ENTER/MARK.

3. From the ‘Save Back Through’ window, highlight the desired time, date, or ‘Entire Log’ and press

ENTER/MARK.

4. Next, the track will begin saving and then display the ‘Saved Track’ window when done. The default
name, distance and number of points (500 max) will be displayed. To change the name of the
saved track, highlight the name fi eld and press ENTER/MARK, make your changes and press
ENTER/MARK again. If you wish for the saved track to be displayed on the Map and Highway
page, highlight the check box to the left of ‘Show on Map and Highway’ and press ENTER/MARK.
Highlight ‘OK’ and press ENTER/MARK to save the track.

To activate a TracBack using the NAV key:

1. Press the NAV key, then highlight the ‘Follow Track’ option and press ENTER/MARK.

2. Highlight the track you wish to follow and press ENTER/MARK.

3. Choose either ‘Original’, which will navigate you from the start to the end of your trip, or ‘Reverse’,
which will navigate you from the end to the start of your trip and press ENTER/MARK.

Once a TracBack has been activated, the GPSMAP 182/232 will take the track log currently stored
in memory and divide it into segments called ‘legs’. Up to 50 temporary ‘turns’ (BEGIN, TURN 1,

TURN 2, TURN 3,...., TURN X, END) will be created to mark the most signifi cant features of the track

log in order to duplicate your exact path as closely as possible. To get the most out of the TracBack
feature, remember the following tips:

• Always clear the track log at the point that you want to go back to (dock, etc.).

• The ‘Record Mode’ option on the track log setup page must be set to ‘Fill’ or ‘Wrap’.

• There must be at least two track log points stored in memory to create a TracBack route.

• If the track log interval is set to the ‘Time’ option, the route may not follow your exact path (keep the
interval set to ‘resolution’ for best performance).

• If the receiver is turned off or satellite coverage is lost during your trip, the TracBack will draw a
straight line between any point where coverage was lost and where it resumed.

• If your track log’s changes in distance and direction are too complex, 50 waypoints may not mark
your path accurately. The receiver then assigns the 50 waypoints to the most signifi cant points of
your track, and simplifi es segments with fewer changes in direction.

To stop TracBack navigation:

1. Press the NAV key, highlight ‘Stop Navigation’ and press ENTER/MARK.

For more information on setting up the Track options and saved tracks, see pages 59-60.

MOB

The GPSMAP 182/232’s Man OverBoard function (MOB) lets you simultaneously mark and set a

guide you back to the MOB point. The MOB waypoint will be stored in the waypoint list and may
be deleted like any other waypoint.

To stop navigation to the MOB position:

1. Press the NAV key, highlight ‘Stop Navigation’ and press ENTER/MARK.

Routes

The last way to navigate to a destination is to create a user-defi ned route. The GARMIN GPSMAP
182/232 system lets you create and store up to 50 reversible routes (numbered 1-50), with up to 50
waypoints each. Routes can be created and modifi ed in two ways. The fi rst way to the ‘Edit on Map’
from the Route Edit map page, allowing you to see each route graphically on-screen as you create,
review, or modify the route. The second way is to ‘Edit as Text’ from the Route Review page, allowing
you to see a list of the waypoints as you create, review, or modify the route. All of the GPSMAP

182/232’s route functions are accessed through the Main Menu page or the NAV key.

To create a route graphically from the Route Edit map page:

1. Press the MENU key twice to display the Main Menu page.

2. Use the ARROW KEYPAD to highlight the ‘Route’ tab and press the MENU key to display
the route options page or you may also highlight the fi rst available blank route slot and press
ENTER/MARK. (Skip to step 4 if you use this method.)

3. Select the ‘New Route’ option and press ENTER/MARK.

GPS Tab— provides a visual reference of satellite acquisition, receiver status, and accuracy. The
status information will give you an idea of what the receiver is doing at any given moment. The sky
view and signal strength bars give you an indication of what satellites are visible to the receiver and
whether or not they are being tracked. The signal strength is shown on a bar graph for each satellite,
with the satellite number below. As the receiver locks onto satellites, a signal strength bar will appear
for each satellite in view. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Light signal strength bars— the receiver has found the satellite(s) and is collecting data.

• Dark signal strength bars— the receiver has collected the necessary data and the satellite(s) are ready
for use.

As soon as the GPSMAP 182/232 has collected the necessary data from the best satellites in view
to calculate a fi x, the status fi eld will indicate a 2D or 3D status. The unit will then update the
position, date and time.

You can use the sky view to help determine if any satellites are being blocked, and whether you
have a current position fi x (indicated by a ‘2D’,‘2D Differential’,‘3D’, or ‘3D Differential’ in the status
fi eld). The sky view shows a bird’s-eye view of the position of each satellite relative to the receiver’s
last known position. The outer circle represents the horizon (north up), the inner circle 45º above the
horizon, and the center point a position directly overhead. You can also set the sky view to a ‘Track Up’
confi guration, causing the top of the sky view to align along your current track heading.

WAAS Capability

The GPSMAP 182/232 is capable of receiving WAAS (Wide Area Augmentation System) satellite
signals. WAAS is an FAA (Federal Aviation Administration) funded project to improve the overall
accuracy and integrity of the GPS signal for aviation use, but land/sea based users may also benefi t
from this system. At this time, the system is still in the development stage and is not fully operational.
There are currently two WAAS satellites that can be received in the U.S.A., one over the Atlantic
Ocean and one over the Pacifi c Ocean, in a geo-stationary orbit over the equator. Effective use of the
WAAS satellite signal may be limited by your geographic location in relation to those satellites, now in
developmental service. WAAS satellite signal reception requires an absolute clear view of the sky and

works best when there are no nearby obstructions such as buildings, mountains, etc. WAAS satellites
will be numbered 33 or higher when viewing the sky view on your GPSMAP 182/232. Initial reception
of the WAAS signal may take up to 15-20 minutes, then 1-2 minutes afterwards. When WAAS
differential correction has been received for GPS satellites (numbers 32 or below), a ‘D’ will appear in
the signal bar of the sky view and ‘2D or 3D Differential’ will appear in the receiver status. To learn
more about the WAAS system, its satellite positions and current state of development, visit the FAA
web site (http://gps.faa.gov). Since WAAS requires CPU resources of the GPSMAP 182/232 to search
for and track the satellites, you may disable the WAAS feature to improve unit performance if WAAS
reception is not available in your area.

To Disable/Enable WAAS capability:

1. From the GPS tab, press MENU, then use the ARROW KEYPAD to highlight ‘WAAS Off’ or ‘WAAS
On’ and press ENTER/MARK.

Receiver Status, Accuracy and DOP

Receiver status is indicated at the top fi eld of the page, with the current Accuracy and Dilution Of
Precision (DOP) to the right of the sky view. DOP is an indication of satellite geometry quality measured
on a scale of one to ten (lowest numbers the best, highest numbers the poorest). Accuracy uses DOP
and other factors to calculate horizontal position accuracy in feet or meters. The status fi eld will show
one of the following conditions:

• Looking For Satellites— the receiver is looking for any satellites.

• AutoLocate— the receiver is looking for any satellite whose almanac has been collected. This
process can take up to fi ve minutes.

• Acquiring Satellites— the receiver is looking for and collecting data from satellites visible at its last
known or initialized position, but has not collected enough data to calculate a fi x.

• 2D— at least three satellites with good geometry have been acquired and a 2 dimensional position
fi x (latitude and longitude) is being calculated. ‘2D Differential’ will appear when you are receiving
DGPS corrections in 2D mode and a ‘D’ will show on the strength bar of satellites being corrected.

• 3D— at least four satellites with good geometry have been acquired and your position is now
being calculated in latitude, longitude and elevation. ‘3D Differential’ will appear when you are
receiving DGPS corrections in 3D mode and a ‘D’ will show on the strength bar of satellites being
corrected.

• Poor GPS Coverage— the receiver is no longer tracking enough satellites for a 2D or 3D fi x.

• Receiver Not Usable— the receiver is unusable, possibly due to interference or abnormal satellite
conditions. Turn the unit off and back on to reset.

• Simulating— the receiver is in simulator mode.

The Differential Receiver status will show one of the following:

• Off— No optional beacon receiver attached or enabled in the Comm menu or WAAS Off

• Searching For WAAS— WAAS is enabled and receiver is searching for WAAS signal

• Using WAAS— WAAS capability enabled and unit receiving WAAS corrections

• No Beacon Signal— DGPS receiver attached, but not transmitting RTCM data to GPS

• Tuning Beacon— Receiver is tuning manual DGPS frequency

• Receiving Beacon— Unit is receiving DGPS corrections

• Scanning Beacon— DGPS receiver is scanning for available frequency

The Differential SNR (Signal to Noise Ratio) indicates, on a scale to 0-30db with 30db being the
best, the strength of the DGPS signal being received. If no optional DGPS receiver is used with the
GPSMAP 182/232, the ‘DGPS Rcvr’ fi eld will display ‘Off. The SNR will depend upon the mounting of
your DGPS receiver and the distance from the DGPS transmitting station.

system covers the entire United States and the U.S. Coastal Confl uence Zone. From the perspective
of a mariner, the system is used for ocean and coastal navigation. It can be used as a supplemental
system for harbor and harbor approach navigation, and it is used for inland navigation by recreational
vehicles.

LORAN TD Feature

The LORAN TD (Time Delay) feature eases the transition from using LORAN to using GPS. The
GPSMAP unit automatically converts GPS coordinates to LORAN TDs for those who have a collection
of LORAN fi xes for favorite fi shing spots and other waypoints recorded as TDs. You can display your
position as a TD or enter waypoints as TDs. The accuracy to be expected from this conversion is
approximately thirty meters. When the unit is placed in the LORAN TD format mode, it simulates
the operation of a LORAN receiver. Position coordinates may be displayed as TDs, and all navigation
functions may be used as if the unit was actually receiving LORAN signals.

Using the LORAN TD Format

When creating new waypoints using LORAN TD coordinates, you must set the correct LORAN
chain number and secondary stations in the Setup TD fi eld before storing the waypoint. You must have
the correct chain number as well as the secondary station identifi ers to use this option correctly. These
values will vary per coordinate set or geographical location. Failure to enter correct information could
result in inaccuracies for the desired destionation. After the waypoint is stored in unit memory, it will
always reference the LORAN chain number and secondary stations currently selected in the Setup TD
fi eld. If you enter a different LORAN chain number, change the secondary stations or offsets in the
Setup TD fi eld, the active waypoint information will refl ect those changes. Since the GPSMAP unit does
not rely on the LORAN signal for navigation, it can reference a different GRI chain and/or secondary
stations and still navigate to the location stored in memory.

The LORAN Position Format fi eld is located under the Units tab in the Main Menu. The ‘LORAN
TD Setup’ window contains the fi elds to select the Loran GRI-Chain Number, Primary and Secondary
Stations, and TD Offsets.

To setup Loran TD from the Main Menu:

1. Using the ARROW KEYPAD, highlight the “Units” tab and then the “Position Format” fi eld and
press ENTER/MARK. You may also press MENU from the “Units” tab to display the ‘Loran TD On’
option. (If you use ‘Loran TD On’, skip to step 3.)

2. Highlight ‘Loran TD’, press ENTER/MARK, then highlight ‘Setup’ and press ENTER/MARK.

3. To change the settings of any of the fi ve fi elds, highlight the fi eld, press ENTER/MARK, select/enter
the desired setting and press ENTER/MARK.

4. When done, press the QUIT key to return to the Main Menu.

If the active GRI Chain, secondary stations or offsets have been changed since the waypoint was
created, the waypoint will now reference the active GRI-chain and secondary stations and adjust the
TD coordinates accordingly. Remember that the GPS is not relying on the LORAN signal for navigation
and actually converts the TD coordinate to a useful LAT/LON coordinate (in the background) before
storing the waypoint to memory or using it for navigation. Because of this the unit can navigate to a
TD coordinate anywhere in the world.

For more information on Loran TDs, you may download GARMIN’s “Loran TD Position Format
Handbook” from the GARMIN web site at http://www.garmin.com/support/userManual.html.

Time Offsets

H

A simple way to determine your local time offset is how
many hours you are behind or ahead of UTC (also called
‘Greenwich’ or ‘zulu’ time).
Example: EST (Eastern Standard Time) is 5 hours behind
UTC, so your offset would be -5. Adding one hour for
daylight savings would make EDT (Eastern Daylight Time)

- 4. Subtract an hour for each time zone as you travel
west.

Offsets for Continental U.S. would be:
EST -5 EDT -4
CST -6 CDT -5
MST -7 MDT -6
PST -8 PDT -7

The chart below gives an approximate UTC (Universal Time Coordinate) time offset for the various
longitudinal zones. Check with local charts for more detailed information. If you are in daylight savings
time, add one hour to the offset.

Antenna Installation

Suggested locations for mounting the GA 29 antenna.

It is possible to route the coaxial cable either through, or
outside the antenna mount. It is possible to remove the
BNC connector on the coaxial cable and the coaxial cable
shortened to ease installation, however, doing so will void the
antenna warranty. If the BNC connector is removed it must
be replaced with a new solder-on or crimp BNC connector.

Installing the GPSMAP 182/232

The GPSMAP 182/232 must be properly installed according to the following instructions to get the
best possible performance. If you have the GPSMAP 182 with the built-in internal bail mount antenna
(010-00238-01), you may skip this section and proceed to the next page. For 182/232 unit’s purchased
with the external GA 29 antenna (010-00238-00/010-00250-00), follow the instructions below. To
complete the installation, you’ll need the appropriate fasteners and a 1” x 14-thread marine antenna
mount available at most marine dealers. When in doubt, seek professional assistance.

Mounting the GPS Antenna

The antenna should be mounted in a location that has a clear, unobstructed view of the sky in all
directions to ensure the best reception. Avoid mounting the antenna where it will be shaded by the
boat’s superstructure, a radome antenna, or mast. Sailboat users should avoid mounting the antenna
high on the mast to prevent inaccurate speed readings caused by excessive heeling. Most marine
VHF and LORAN antennas should not seriously degrade the GPS antenna’s reception. Never paint the
antenna or clean it with harsh solvents.

The GARMIN antenna screws directly onto any standard 1” x 14-thread antenna mount. If you
need to raise the antenna to avoid shading, try using a 1” x 14-thread extension mast available at
most marine dealers.

To install the GPS antenna:

1. Screw the antenna directly onto the 1” x 14-thread mount.

2. Route the cable to the mounting location of the display unit. Use the appropriate tie-wraps,
fasteners and sealant to secure the cable along the route and through any bulkhead or deck.

3. Once the GPSMAP 182/232 unit has been installed, connect the cable to the antenna connector
on the back of the display unit. Make sure that you turn the antenna cable connector 1/4 turn
clockwise to lock the cable into place.

Mounting the GPSMAP 182/232 Unit

The GPSMAP 182/232’s compact, waterproof case is suitable for mounting in exposed locations
or at the nav station. The unit comes with a gimbal bracket that can be used for surface or overhead
mounting. When choosing a location for the display unit, make sure you consider the following
conditions:

• There should be at least a 3” (5 cm) clearance behind the case to allow connection of the
antenna (external antenna only), power/data cables.

• The mounting surface should be heavy enough to support the unit and protect it from excessive
vibration and shock.

• For GPSMAP 182 unit’s with the built-in internal bail mount antenna (010-00238-01), it should
be mounted in a location that has the clearest, most unobstructed view of the sky in all directions
to ensure the best reception. Avoid mounting the unit where it will be blocked by the boat’s
superstructure, a radar arch, or mast.

The temperature range for the GPSMAP 182/232 is 5°F to 158°F (-15°C to 70°C).

I

Extended exposure to temperatures exceeding this range (in storage or operating
conditions) may cause failure of the LCD screen. This type of failure and related
consequences are NOT covered by the manufacturer’s limited warranty.

To install the GPSMAP 182/232 unit:

1. Place the mounting bracket in the desired location.

2. Mark and drill the four mounting holes for the fastener you are using.

3. Fasten the bracket to the surface using the appropriate fastener.

4. Insert the GPSMAP 182/232 into the mounting bracket. The bracket is designed for a tight fi t to
provide additional support when swiveling the unit.

5. Screw the two mounting knobs through the bracket and into the display case.

6. Connect the power/data and antenna cables (external antenna only) to the back of the unit, making
sure the locking rings are fully tightened on both connectors.

Pull gimbal bracket down
until cam lobe contacts
surface.

The GPSMAP 182 with external antenna (010-00238-00) can be fl ush mounted on a fl at panel of
.08-.52” thickness using the cam lobe feature on its gimbal mounting bracket. When fl ush mounting
the GPSMAP 182/232, be sure to choose an appropriately sized location for the unit (see unit dimen­sions pg. 83) and leave 1.25” (32mm) clearance below the data card slot for inserting/removing data
cards. For fl ush mounting the GPSMAP 232, skip to the next set of instructions.

To fl ush mount the GPSMAP 182 unit using the gimbal mounting bracket:

1. Cut a 4.33”W x 4.33”H (110 x 110 mm) hole in the panel.

2. Place the GPSMAP 182 into the hole from the front until the fl ange rests against the mounting
surface.

3. From the back of the panel, loosely attach the bracket such that the slot in the ratchet area points
away from the mounting panel (fi gure 1).

4. Rotate the bracket downward until the panel is pinched tightly between the unit’s fl ange and
bracket lobe (fi gure 1).

5. Tighten the knobs and connect the power/data and antenna cables. Note: if the panel is too thick to
allow use of the supplied knobs, two M6 screws may be used to secure the bracket.

The GPSMAP 182/232, with external antenna, may also be fl ush mounted on a fl at panel using

its existing mounting bracket.

To fl ush mount the GPSMAP 182/232 unit:

1. Remove the four M5 screws from the back of the unit and remove the mounting bracket.

2. Using the mounting bracket as a template, outline the center relief area and mark the location of
the four screw holes centers on your bulkhead or other surface (fi gure 2).

3. Cut the relief hole from the panel and drill the four 0.20” (5.08 mm) screw holes.

4. Place the GPSMAP 182/232 into the relief hole until it rests fl ush against the mounting surface.

5. Secure the unit to the mounting surface using the M5 screws. Do not try to force the screws deeper
into the holes than the holes will allow. For thick mounting surfaces, insert the M5 screws directly
thru the drilled holes (fi gure 3). For thin panels, place the mounting bracket on the back side of the
panel for more support. Connect the power/data and antenna cables.

Connecting the Power/Data

The power/data cable connects the GPS 182/232 to a 8-35 volt DC system and provides interface
capabilities for connecting external devices. The color code in the diagram below indicates the
appropriate harness connections. Replacement fuse is a AGC/3AG - 1.5 Amp fuse.

Installing and Removing

Data Cards

The fi rst time you insert a
data card, the unit will take a
few seconds to read the card.

Once the data card has been
read, a summary screen will
appear. Press ENTER/MARK
to acknowledge.

Installing and Removing Data Cards

The GPSMAP 182/232 uses optional GARMIN marine BlueChart and MapSource data cards to
display digital charts and maps on-screen. Data cards are installed in the card slot located at the bottom
right of the unit. Data cards may be installed or removed at any time, whether the unit is on or off.

To install a data card:

1. Open the card door by pressing together on the two handles at the bottom of the door and
lifting it up and open.

2. Insert the card, with the label facing front and the handle bottom, into the slot.

3. Firmly push the card into the unit. It in not necessary to force the card and about 1/2” will still
be exposed when it is properly inserted. If the unit is on, a confi rmation tone will sound and
a message will display on the screen noting the card details when the card has been properly
installed and accepted.

4. Close the cover.

If you insert a data card and get a ‘card format not recognized’ message, try removing the card
and reinserting it. If the card is still not recognized, contact the GARMIN or your GARMIN dealer for
assistance. Data cards are not waterproof, should not be exposed to moisture or excessive static charges,
and should be stored in the case supplied with the card.

To remove a data card:

1. Open the card door by pressing together on the two handles at the bottom of the door and
lifting it up and open.

2. Grasp the card handle at the bottom and pull down fi rmly.

3. If the unit is on, a confi rmation tone will sound when the data card has been removed.
