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 162 is a precision electronic
NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted and, therefore, become
unsafe.

Introduction

Warning and Precautions

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 162 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 162 to all
available navigation sources, including the information from other NAVAIDs, visual sightings, charts, etc.
For safety, always resolve any discrepancies before continuing navigation.

MAP DATA INFORMATION: One of the goals of GARMIN is to
provide customers with the most complete and accurate cartography
that is available to us at a reasonable cost. We use a combination
of governmental and private data sources, which we identify (as
required) in product literature and copyright messages displayed
to the consumer. Virtually all data sources contain inaccurate or
incomplete data to some degree. This is particularly true outside the
United States, where complete and accurate digital data is either not
available or prohibitively expensive.

NOTE: This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications.
There is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference, the user is encouraged to try to correct the interference by relocating the
equipment or connecting the equipment to a different circuit. Consult an authorized dealer or other
qualifi ed technician for additional help if these remedies do not correct the problem.

This device complies with Part 15 of the FCC limits for class B digital devices for home or offi ce use.
Operation is subject to the following conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired

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 pop-up a sub-menu or list of yet more feature options. Just repeat this process to select

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.

Warning Screen

The GPSMAP 162’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 162. We strongly encourage you to take the Getting
Started tour before using your unit for actual navigation.

The GPSMAP 162 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 162.

Initializing the Receiver

The fi rst time you power up your new GPSMAP 162, the receiver must be given an opportunity to
collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 162
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 162 unit and antenna have been correctly installed
on your vessel according to the instructions in Appendix G. The antenna needs to have a clear and
unobstructed view of the sky to receive satellite signals.

To turn the GPSMAP 162 on:

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

The welcome page will appear while the unit conducts a self-test. Once the internal test is
complete, 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.

4

To graphically initialize the GPSMAP 162:

1. From the Status Page, press the MENU key. The Status Page options menu window will appear.

2. Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER/MARK to initialize the
receiver from the built-in worldwide 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
100 miles. If you have diffi culty identifying your position, press and release the IN key to zoom in
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 switches to the Map Page or displays ‘2D’ or ‘3D
Navigation’ during this process, it is not necessary to initialize the unit.

The GPSMAP 162 will now begin searching for the appropriate satellites for your region and should
acquire a fi x within a few minutes. A signal strength bar for each satellite in view will appear on the
top middle 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 “2D or 3D Navigation”, and the GPSMAP 162 will be ready for use.

Getting Started

Initializing the Receiver

Point to your approximate location
and press ENTER/MARK.

A satellite’s signal bar will turn black
when it’s ready for use.

GPSMAP 162 Getting Started Tour

The GARMIN GPSMAP 162 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 on the GPSMAP 162:

1. Press and hold the POWER key until the power tone sounds, then release the POWER key. The
Welcome 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 Status Page will appear as the receiver begins acquiring satellites. From the Status Page 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 162’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.

6

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.

The GPSMAP 162’s Status Page provides a visual reference of satellite acquisition, receiver status,
date, time and position coordinates. Each page of the GPSMAP 162’s system also features an options
menu, giving you access to other functions and features related to the specifi c page you are viewing. To
get a feel for how the options menus work, let’s put the GPSMAP 162 into simulator mode.

To place the GPSMAP 162 in simulator mode:

1. From the Status Page, press the MENU key. A menu of options and functions for the Status Page
will appear.

2. Press UP DOWN on the ARROW KEYPAD to highlight the ‘Start Simulator’ option and press
ENTER/MARK.

3. Press the ENTER/MARK key to confi rm the ‘Running Simulator’ message that appears at the
bottom of the display.

Once the simulator has been started, the status fi eld at the top of the page will display a ‘Simulating

Navigation’ status. Now you’re ready to continue the rest of the simulated tour.

The GPSMAP 162 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.

When the unit is in simulator mode,
an ‘S’ will appear in the lower left
corner of every screen and the Satel­lite Page will show “Simulating Navi­gation.”

Status Page/

Map Page

The Status Page is one of fi ve main pages used in the GPSMAP 162’s system. The fi ve main pages
are: the Status Page, Map Page, Compass 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.

Status Page

To continue the tour, let’s move on to the next page, the Map Page.

To scroll to the next page in sequence:

1. Press the PAGE key.

The GPSMAP 162’s Map Page combines digital chartplotting with a user-selectable display of
navigation data and a built-in worldwide database to 20 mi. 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 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 course, speed over ground, and bearing and distance to the cursor or a
particular waypoint. The current map scale setting is located at the bottom right of the page.

Map Page Active Route PageHighway Page

Compass 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 at the
top of the page, 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 Status and Map Pages can be used to monitor satellite acquisition
and 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 162’s keypad and ENTER/MARK key are used for
data entry and changing the waypoint name and symbol.

Marking Waypoints

Press ENTER/MARK after entering

the name.

You can choose from a list of 38 useful

symbols.

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 the UP or DOWN arrow of the ARROW KEYPAD until the letter ‘D’ appears, and then press
the RIGHT arrow key 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 menu, 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. You may also press QUIT to not 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 162 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/MOB key, located on the right side of the keypad below the QUIT key, is the primary
tool used to select a destination waypoint, TracBack, or a route to navigate. The NAV/MOB key can
be used in three primary ways:

• Pressing NAV/MOB once displays a list of options from which you can select ‘Go To Waypoint’,
‘Follow Route’, ‘Follow Track’, or ‘Stop Navigation’.

• Holding down NAV/MOB, or pressing the key 2 times, activates the MOB (Man OverBoard)
feature. This marks the point at which the MOB was activated as a waypoint named “MOB” and
also establishes it as an active “Go To” point.

• Highlighting an on-screen waypoint or map item as a destination directly from the Map Page
and pressing NAV/MOB 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 you how the MENU key provides tab style options and functions throughout the
GPSMAP system. Let’s start by changing the position to where the practice route is located.

To change the GPSMAP 162 position in simulator mode:

1. From the Status Page, press the MENU key. The options menu will appear, displaying a menu of
options and functions for the Status Page.

2. Press UP or DOWN on the ARROW KEYPAD to highlight the ‘Initialize Position’ option and press
ENTER/MARK.

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

4. 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.

Simulated Tour

You can also Invert a route to follow

it in reverse.

The Set Position, Track Control, Track
and Speed fi elds will only show while
in simulator mode.

Let’s give it a try by activating the practice route stored in memory for navigation:

1. Press NAV/MOB. The options list 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/MOB 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 get a better view of what’s going on, zoom in to a closer map scale.

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

Note: 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, and a pointer 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. 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.

12

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 data in use, the range
fi eld will display ‘overzoom’ or ‘NO MAP’ 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 or “selected.” 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 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 to a new position on the map that is NOT a map
feature (such as a city, road or lake).

2. Press the ENTER/MARK key to capture the cursor position. The New Map Waypoint page appears.

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 press ENTER/MARK again to save the waypoint.

Now that we’re navigating to an actual destination, let’s move on to the GPSMAP 162 navigation

pages by pressing the PAGE key.

The GPSMAP 162 features two different navigation pages: the Compass and Highway pages. The
Compass Page is fi rst. This page provides graphic steering guidance to a destination waypoint, with an
emphasis on the bearing to your destination and current direction of travel. (The Highway Page places
greater emphasis on the straight-line desired course and the distance and direction you are off course.)
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 and the time to the next waypoint are displayed
at the top of the screen. This page provides better steering guidance than the Highway Page when
traveling at slower speeds and/or when making frequent directional changes. When you are not
navigating to a waypoint, the compass ring will show your direction of travel as you move but the
arrow will not appear.

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

14

The GPSMAP 162’s Highway Page also provides graphic steering guidance to a destination
waypoint. 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 six
default data fi elds at the top of the page indicate Speed, Distance To your destination (or the next
waypoint in a route), ‘To Course’ which shows the bearing to get you back on course, the distance
you are ‘Off Course’, Time To the Next waypoint, and compass Track you are heading. 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 162 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 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.

To steer the boat:

1. Press the LEFT and RIGHT arrows of the ARROW KEYPAD.

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 Page 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 Page display:

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

indicate the next point along the route, which is denoted by an arrow on the left-hand side of the
screen. For more detailed information on the Active Route Page, see page 58.

As you’ve seen, the primary pages provide status, map, and navigation information. The tour’s last
page is the Main Menu page, which allows access to the GPSMAP 162’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 13 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.

16

To get a feel for how the Main Menu page works, let’s clear out the track log 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 Track submenu tab:

1. Use the ARROW KEYPAD to highlight the ‘Track’ menu tab. You will see the options for the Track
tab appear to the right of the Main Menu list.

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

The Track Log Page allows you to specify whether to record a track plot, defi ne how it is recorded

Status Page

The GPSMAP 162 Status Page provides a visual reference of satellite acquisition, receiver status,
date, time and position coordinates. 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 indicate which 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, with the appropriate satellite number (01-32) underneath each
bar. 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.

Each satellite has a data transmission that must be collected (light bar status) before that satellite
may be used for navigation (dark bar status). When the receiver is looking for a particular satellite,
the corresponding signal strength bar will be blank and the sky view indicator will not be highlighted.
Once the receiver has found the satellite, a light signal strength bar will appear, indicating that the
satellite has been found. When the receiver has collected data from the satellite and locked on, the
number in the sky view will appear highlighted and the status bar will become dark.

As soon as the GPSMAP 162 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 tatus. 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 Navigation’ or ‘3D Navigation’ 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.

18

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 Navigation— 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 Naviga­tion’ 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 Navigation— at least four satellites with good geometry have been acquired and your
position is now being calculated in latitude, longitude and altitude. ‘3D Differential Navigation’
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 Navigation— the receiver is in simulator mode.

The ‘DGPS Rcvr’ and ‘Diff SNR’ fi elds appear below the ‘Accuracy’ and ‘DOP’ fi elds. The

Differential Receiver status will show one of the following:

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

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

• Tuning— Receiver is tuning manual frequency

• Scanning— DGPS receiver is scanning for available frequency

• Rcving— Unit is receiving DGPS corrections

• Chk Wiring— DGPS is enabled in Comm menu, but no DGPS receiver attached or bad
corrections

• WAAS— The unit is receiving ‘WAAS’ data

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 162, the ‘DGPS Rcvr’ fi eld will display ‘Off’ and the ‘DGPS SNR’ fi eld will be blank.
The SNR will depend upon the mounting of your DGPS receiver and the distance from the DGPS
transmitting station.

Many features of the GPSMAP 162 are menu-driven. Each of the main pages has an options menu,
allowing you to custom tailor the corresponding page to your preferences and/or select special features
that specifi cally relate to that page.

The GPSMAP 162’s Status Page features an options menu that provides access to functions and
features relating to the Status Page.

To display the Status Page options:

1. Press MENU.

To select a menu option:

1. Using the ARROW KEYPAD, highlight the desired option and press ENTER/MARK.

The following options are available:

• Start/Stop Simulator— allows you put the unit in simulator mode. See the Getting Started Tour
for more on using simulator mode.

• Enable/Disable WAAS— allows you to activate or deactivate WAAS. ‘WAAS’ is an acronym for
“Wide Area Augmentation System’. You can use the WAAS capability to increase the accuracy of
the GPSMAP 162. When enabled, the GPS receiver searches for a WAAS satellite, then receives
data that will help correct differentials in the GPS signal. When the unit is using WAAS data,
“WAAS” will be displayed in the ‘DGPS Rcvr’ fi eld on the Status Page, and the receiver status
will indicate a 2D or 3D Differential Location.

Currently, the WAAS system is not fully operational and there are only two satellites in

place—one over the Pacifi c Ocean and one over the Atlantic Ocean. You must have a clear,
unobstructed view of the sky for the GPSMAP 162 to be able to receive a WAAS signal. Even
then, at times it may not be possible to receive a WAAS signal. For more information on the
WAAS system, visit the Federal Aviation Administration web site at (gps.faa.gov).

• Track Up/North Up— allows you to select between a north up or track up sky view display
for the Status Page only.

• Loran TD On/Off— allows you to toggle the position coordinate format between latitude/
longitude and Loran TD (Time Delays). For setup of Loran TD, see pages 72-73.

• AutoLocate— allows the receiver to locate your position automatically. This process can take
up to fi ve minutes.

• Initialize Position— allows you to initialize the receiver graphically on the Map Page to initially
help the receiver acquire more quickly. See pages 4-5 for instructions on initialization.

• Set 2D Altitude— allows you to manually enter the altitude when in 2D Navigation or
Simulator mode only. Any altitude entered will be automatically calculated when the GPS is

The GPSMAP 162’s Map Page provides a comprehensive display of electronic cartography, plotting
and navigational data. When using the unit with the optional 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 IN and 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.

• If the boat icon attempts to go off the display, the zoom level may need to be adjusted to
keep cartography on screen.

When the ARROW KEYPAD is pressed, the GPSMAP 162 will enter cursor mode. In cursor

mode:

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

• When 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.

Compass Page

The GPSMAP 162 features two different navigation pages: Compass and Highway. Whenever a
NAV/MOB, Follow Track (TracBack) or Follow Route have been activated, the GPSMAP 162’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, in the middle of the compass ring, 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 GPSMAP 162’s Compass Page features a menu page that provides access to layout and data
fi eld options. The data window, located at the top of the page, provides a user-selectable layout of
various types of useful data. Each data fi eld may be confi gured to display any one of 23 data options.
The data window layout may also be changed to display additional data fi elds and change the actual
size of the data displayed.

Whenever a NAV/MOB, TracBack or route has been activated, the GPSMAP 162’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. The
middle 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.

symbol, name or depth.

Creating and Using Waypoints

The GARMIN GPSMAP 162 stores up to 500 alphanumeric waypoints with a user-defi ned icon and

depth available for each waypoint. Waypoints can be created using three 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.

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

ARROW KEYPAD.

• Text Entry– allows you to enter a new waypoint’s position coordinates manually.

ENTER/MARK Key

The GARMIN GPSMAP 162’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 Status Page.
When you move the cursor over a map item, you will see a highlighted description of that item.

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

Creating Waypoints Graphically

Waypoints may also be quickly created using the map display. This feature allows you to select any
map position with the cursor and create a new waypoint. To mark a map item, select the desired map
item with the cursor then press and release the ENTER/MARK key. If you select an item on the map,
like a city, the GPSMAP 162 will use the text or name shown on the cartography as the default name.
When selecting a map item, the option ‘Create Waypoint’ 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 quickly release the ENTER/MARK key. The ‘New Map Waypoint’ page appears. (NOTE:
Pressing and holding the ENTER/MARK key will mark your current location instead of the cursor
location, and bring up the ‘New Waypoint’ page)

If you are using a map item to create a waypoint, an information page(s) for the map item will

appear fi rst. Use the ARROW KEYPAD to highlight ‘Create Waypt’ and press ENTER/MARK. The
‘New Waypoint’ page will now appear.

3. To accept the waypoint with the default name and symbol, press ENTER/MARK. If you are creating
a waypoint from an on-screen map item, the name and symbol will automatically refl ect the
selected map item’s name and symbol.

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

5. After entering and confi rming your changes, highlight ‘OK’ and press ENTER/MARK.

Going to a Destination

Using the NAV/MOB key, the GPSMAP 162 provides four ways to navigate to a destination: Go To
Waypoint, Follow Track (TracBack), MOB (Man OverBoard), and Follow Route navigation. Once you
are actively navigating, you will see a straight line that always runs from the point where you started the
GOTO, to the destination. The easiest method for selecting a destination is the ‘Go To’ function, which
lets you select a destination waypoint and quickly sets a direct course from your present position.
If you have a waypoint highlighted on a list or the map, ‘Go To <waypoint name>’ will appear in
addition to ‘Go To Waypoint’. The ‘Go To’ function can be accessed from a list of waypoints or
graphically from the map display.

46

To activate a ‘Go To’ from the fi nd list:

1. Press the NAV/MOB key.

2. Use the ARROW KEYPAD to highlight ‘Go To Point’ and press ENTER/MARK. The ‘Find’ list will
be displayed.

3. Select a catagory (i.e. Waypoint, City, Facitilies, Transportation) from the ‘Find’ list, then using the
ARROW KEYPAD select a point from that catagory. Press ENTER/MARK to display a review
page for the selection, then with the ‘GO TO’ button highlighted, press ENTER/MARK to begin
navigation.

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 162 will automatically
use the name of the map item, but the point will not be stored in the waypoint list. See page 39
for creating waypoints using map items. If you are selecting a new map point (non-map item) as
the ‘Go To’ destination, the GPSMAP 162 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/MOB.

2. You will see ‘Go To <waypoint name>’, then 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/MOB, you will see ‘Go To MAP Point’ highlighted, then press ENTER/MARK.

TracBack Navigation

‘Go To MAP Point’ allows you to

navigate to a spot on the map which

is not a waypoint or map item.

Highlight ‘Save’ and press ENTER/MARK
to save an active track log.

TracBack Navigation (Follow Track)

The second method of navigating to a destination is by using the TracBack 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 30 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
good idea to clear the existing track log at the start of your current trip before you get started.

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 ‘Clear’ 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 a track log 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 will be displayed. Highlight ‘OK’ and ENTER/MARK press
to save the track.

48

To activate a TracBack using the NAV/MOB key:

1. Press the NAV/MOB 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 end to the start of your trip, or ‘Reverse’,
which will navigate you from the start to the end of your trip and press ENTER/MARK.

Once a TracBack has been activated, the GPSMAP 162 will take the track log currently stored in
memory and divide it into segments called ‘legs’. Up to 30 temporary ‘turns’ 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, 30 waypoints may not
mark your path accurately. The receiver then assigns the 30 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/MOB key, highlight ‘Stop Navigation’ and press ENTER/MARK.

2. Choose either ‘Yes’ or ‘No’ and press ENTER/MARK to confi rm.

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/MOB key, highlight ‘Stop Navigation’ and press ENTER/MARK.

2. Choose either ‘Yes’ or ‘No’ and press ENTER/MARK to confi rm.

Routes

The last way to navigate to a destination is to create a user-defi ned route. The GARMIN GPSMAP
162 system lets you create and store up to 20 reversible routes, with up to 30 waypoints each. Routes
can be created and modifi ed in two ways. The fi rst 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. The second way
is from 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. All of the GPSMAP 162’s route functions are
accessed through the Main Menu page or the NAV/MOB key.

To create a route using text from the Route Review 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

tab Page also provides an indicator of the memory used for the active track log and options to clear
the track memory or start a TracBack route. See pages 48-49 for TracBack information. The Track
submenu is divided in two tabs: ‘Active’ tab and the ‘Saved’ tab.

The ‘Active’ tab is for the active log (the log currently being recorded). It displays track memory
used and current settings. The ‘Saved’ tab displays and manages a list of any saved track logs, allows
TracBack activation, map display of saved logs. The active log stores up to approximately 2000 track
log points, based upon the criteria specifi ed in the Track settings. Up to 10 track logs may be saved in
memory, with up to 250 track log points in each saved log.

For the ‘Active’ tab, the following settings are available:

• Record Mode— lets you select one of three track recording options:

Off— No track log will be recorded. Note that selecting the ‘Off’ setting will prevent you from

using the TracBack feature.

Fill— a track log will be recorded until the track memory is full.

Loran TD

You may change to Loran TD from either the
Satellite Page or Units Tab on the Main Menu.

Loran TD System

LORAN C is a radio navigation aid operated and maintained in the United States by the United
States Coast Guard. The name LORAN is an acronym for “LOng RAnge Navigation”. The LORAN
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. 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.

72

To setup Loran TD from the Main Menu:

1. Using the ARROW KEYPAD, highlight the “Units” tab and then the “Position Format” fi eld press
ENTER/MARK.

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.

To setup Loran TD from the Status Page:

1. Press MENU, then use the ARROW KEYPAD, highlight the ‘Loran TD On’ and press
ENTER/MARK.

2. 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.

3. When done, press the QUIT key to return to the Status Page.

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.

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. The BNC connector on
the coaxial cable can be removed, and the coaxial cable
shortened to ease installation. If the BNC connector is
removed it must be replaced with a new BNC connector.

Installing the GPSMAP 162

The GPSMAP 162 must be properly installed according to the following instructions to get
the best possible performance. If you have the 162 with the built-in internal bail mount antenna
(010-00192-00), you may skip this section and proceed to the next page. For unit’s purchased with the
external GA 29 antenna (010-00191-00), 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.

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 162 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.

82

Mounting the GPSMAP 162 Unit

The GPSMAP 162’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 unit’s with the built-in internal bail mount antenna (010-00192-00), 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 162 is 5°F to 158°F (-15°C to 70°C). Extended

I

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 162 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 162 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.
