GETTING STARTED
Initialization
Intializing the Receiver
The first time you power up your new GPSMAP 185 Sounder is an important step
in getting the best possible GPS performance. The receiver must be given an opportunity to collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 185 Sounder is shipped from the factory in AutoLocate
TM
mode, which will allow the receiver to find itself anywhere in the world. To speed
up the initialization process, we recommend using the graphic initialization process
described below, which will usually provide a position fix in about a minute.
Before you initialize, make sure the GPSMAP 185 Sounder unit and antenna have
been correctly installed on your vessel according to the instructions in Appendix A.
To turn the GPSMAP 185 Sounder on:
1. Press and hold the Pkey until the power tone sounds.
The welcome page will appear while the unit conducts a self test. Once the
internal test is complete, the mariners warning will appear, asking you to read and
acknowledge important information regarding the proper use of electronic charts.
To acknowledge the mariners warning:
1. Press the Tkey.
A message alert and prompt will also appear to ask you to select an initialization
method.
To view a system message:
1. Press the Jkey.
2. Press the
J
key again to return to the previous page.
A. The welcome page will be displayed while
the unit performs a self-test.
B. Confirm the Mariners Warning before
starting navigation. Remember that the

key to zoom in to a lower map
scale.
2. Press
T
to confirm your selection.
The GPSMAP 185 Sounder will now begin searching for the appropriate satellites
for your present position and should acquire a fix within a minute or so. While the
receiver searches for satellites, a flashing satellite icon will appear at the left-hand side
of the status bar located at the bottom of the screen. The status bar is used to monitor
the current status of functions such as satellite signal reception, activated alarms, and
also constantly shows the digital depth. A signal strength bar for each satellite in view
will appear on the lower half 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 col-
lecting data.
Solid signal strength bars the receiver has collected the necessary data and the satel-
lite(s) is ready for use.
Once the receiver has collected information from at least three satellites, the flashing satellite icon on the status bar will glow steadily, and the GPSMAP 185 Sounder is
ready for use.

Page Sequence/Position Page
The satellite status page is one of five main pages used in the GPSMAP 185
Sounders system. All five pages are linked together in a simple chain, which
allows you to scroll through the pages in either direction using the
J
and
Q
keys. To continue the tour, lets move on to the next page, the position page.
To scroll to the next page in sequence:
1. Press the Jkey.
The GPSMAP 185 Sounders position page shows where you are, what direction
youre heading and how fast youre going. The compass tape at the top of the page

with a custom icon for fast waypoint recognition.
1. Press the Jkey.
The sounder page lets you use the GPSMAP 185 as a fishfinder. The top of the screen
contains any of thirteen selectable data field options, while the middle of the page contains a
right-to-left moving sonar image of the water beneath your boat. (Note: Items appear on the
screen as they pass under your transducer. Those objects appearing on the right side of the
screen are closer to you than those on the left.) Fish are displayed as a darkened arch or a
fish icon in three different sizes. Thermoclines (layers of water separating warmer water
above from cooler water below) are shown as shades of gray.
The area of strongest sonar return (or whiteline) is displayed as a solid gray. Typically, the
bottom will be the primary source of the whiteline. A thin whiteline indicates a softer bottom while a thick whiteline shows a harder bottom. A black line is used to show the point
where water meets the whiteline. This black line will follow the bottom contour, along with
any significant objects lying on the bottom. Along the right side of the screen is an adjustable
scale which reflects the depth of the area being displayed. The status bar at the bottom of the
page displays satellite signal status, digital depth, and any triggered alarms. More on the

Using the Map Cursor
Working from the map page is a simple process that centers around the use of
the cursor. Controlled by the
R
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 navaids and waypoints.
To get a feel for using the map page and using the cursor, try the following
exercise:
1. Use the Ckey to set the map scale to the 64 nm setting. Your boat should be near the
center of the map, at the receivers last known position. (If your boat isnt 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 DOWN arrow of the
R
keypad to move the cursor down to the first lat/lon grid
south of your boats position.
3. Using the
R
keypad to move the cursor, try following the outline of the lat/lon grid closest to your boat. Notice how another data field appears at the top of the page, showing
the bearing and distance from your boat to the cursor, along with the lat/lon of the cursor.
4. Press the
Q
key to remove the cursor and recenter your boat on the map display.
As you become more familiar with the cursor, youll see that the map display
actively scrolls or pans, letting you explore areas around the world (even outside
of your current Micro G-chart coverage) and create waypoints and routes.
Wherever you move the cursor, youll always be just one
Q
keystroke away
from returning the map to your present position.
Now that you have a feel for how the cursor works, lets move on and see how
the GPSMAP 185 Sounder works on the water. To help you practice using the
map page and other features, weve stored a practice route in the receivers permanent memory so you can see exactly what youll experience when youre navigating with your new GPS chartplotter.
GETTING STARTED
Map Cursor
A. Whenever the cursor is active, the bearing
and distance of the cursor from your present
position will appear in a pop-up data window. To remove the cursor and recenter your
vessel on the map, press the QUIT key.
B. To select an on-screen waypoint, simply
move the cursor over the desired waypoint.
The waypoint/navaid name and position,
along with the bearing and distance from
your present position, will be displayed.
Note: Underwater waypoints are also shown
on the map.

Going to a Destination
GPS is all about marking positions as waypoints and navigating to them using
the receivers steering guidance and map displays. Weve already seen how to use
the
M
key to store our present position, so its time to move on to the fun
partgoing to a destination. The
G
key, located on the left side of the keypad
above the
Q
key, is the primary tool used to select a destination waypoint or a
route to navigate. The
G
key can be used in three primary ways:
Pressing
G
once displays a list of all waypoints in memory, from which
you can select a single destination waypoint.
Pressing
G
followed by the Okey provides a list of GOTO options
that lets you start a TracBack
TM
route, select a destination waypoint from
the nearest waypoints list, select a stored route to navigate, or cancel the
current GOTO destination.
Pressing
G
twice allows you to graphically select an on-screen waypoint,
navaid or cursor position as a destination directly from the map display.
For our simulated trip, were going to select the pre-programmed tour route
[the second method], which will automatically place our vessel at the first route
waypoint. This will also give us an idea of how the
O
key is used throughout
the GPSMAP 185 Sounder system to provide context-sensitive options and functions. Lets give it a try by activating the practice route stored in memory for navigation:
1. Press G. The waypoint list page will appear. (If we were selecting a single waypoint
to navigate to rather than a route, we would highlight the waypoint and press
T
.)
2. Press
O
to display the context-sensitive options available for the GOTO function.
3. Use the
R
keypad to highlight the Select Route? option. Press Tto confirm.
4. The select route page will appear, with the GPSMAP TOUR route highlighted.
5. Press
T
. The map page will reappear and display five waypoints chained together in
a simple route, with your boat at the first route waypoint.

A. Pressing GOTO once displays a list of all way-
points stored in memory. To pick a destination,
select the desired waypoint and press
EDIT/ENTER.
B. The GOTO options page allows you to either
start a TracBack route back home, select a destination from the nearest waypoints list, or
select a route to navigate.
AB
A data field at the top of the page will now display the bearing and distance to
the second route waypoint. To get started, lets enter a speed for our vessel, which
we can do from the Setup Simulator? listing on the options page. The setup simulator page is also available from any other page in the main page sequence.
To enter a boat speed:
1. Press the Okey to display the map options page.
2. Use the
R
keypad to select the Setup Simulator? option and press T.
3. Once the setup simulator page appears, press
T
to access the SOG field.
4. Use the
R
keypad to enter a speed of 60 knots.
5. Press
T
to finish, and Jto return to the map display.
Once a speed has been entered, youll notice that the map will begin to move
slowly, keeping your boat centered on the display. To get a better view of whats
going on, zoom in to a closer map scale.
1. Press the C key to select the 16 nm scale.
Youll now have a clearer picture of the route we are navigating, along with an
outline-only presentation of the surrounding shoreline. Because the usable range
of the built-in database is only valid to 64 nm scale, we no longer have full cartography available. Keep in mind that whenever you do exceed the usable range of
the built-in database or the Micro G-chart cartridge in use, the range field will display OVR ZM or NO MAP to indicate that you should exercise extreme caution
using the cartography data. See pages 39 and 81 for more information on map
scales and using Micro G-chart detailed cartography.
Now that weve zoomed in a little closer to our route, we can pan ahead of our
vessel with the cursor to review and create on-screen waypoints and navaids. Try
moving the cursor to select the TOUR3 waypoint just use the
R
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.)

Navigation Page
Now that were navigating to an actual destination, lets move on to the next
page of the GPSMAP 185 Sounder system, the navigation page:
1. Press the Jkey.
The navigation page provides graphic steering guidance to your destination.
The bearing (BRG) and distance (DIS) to the destination, with your current course
(COG) and speed over ground (SOG), are displayed at the top of the page, along
with a compass tape to indicate your cardinal heading. The estimated time
enroute (ETE) and velocity made good (VMG, or the rate you are closing in on
your destination) are displayed at the bottom of the page.
As you head toward the destination, the middle section of the page gives you
visual guidance to your waypoint on a graphic highway, which displays the route
and nearby waypoints on screen. The moving arrow below the highway always
points to the destination waypoint relative to the direction youre moving. The
line down the center of the highway represents your desired track, while the bottom of the page provides a graphic indication of your crosstrack error (the distance and direction you are off course) according to the scale at the bottom right
of the page.
Whenever the GPSMAP 185 Sounder is in simulator mode, you can adjust your
speed and course from the navigation page using the
R
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.
A. In this example, our boat is off course to the
left by about 1/8th of a mile (the base of the
highway map is equal to the scale selected at
the bottom right of the page). To get back on
course, steer right.
B. In this example, our boat is off course to the
right. To get back on course, steer left. A digital readout of your exact crosstrack error can
be displayed in any of the six data fields (see
page 47).

Power Off
Status Page
The GPSMAP 185 Sounder status page provides a visual reference of various
receiver functions, including current satellite coverage, receiver operating mode
and current receiver 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. When a satellite is visible but not being tracked, the strength bar will not
be shown and the sky view indicator will not be highlighted.
The sky view shows a birds-eye view of the position of each satellite relative
to the receivers last known position. The outer circle represents the horizon
(track up), the inner circle 45º above the horizon, and the center point a position
directly overhead. Use the sky view to determine if there are obstructions shading
your reception of GPS signals.
