GETTING STARTED
Initialization
Initializing the Receiver
The first time you power up your new GPSMAP 180 is an important step in get-
ting the best possible GPS performance. The receiver must be given an opportunity
to collect satellite data and establish its present position. To ensure proper initializa-
tion, the GPSMAP 180 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 initializa-
tion 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 unit and antenna have been correctly
installed on your vessel according to the instructions in Appendix A.
To turn the GPSMAP 180 on:
1. Press and hold the
P
key until the power tone sounds.
The welcome page will appear while the unit conducts a self test. Once the
internal test is complete, the mariners warning will appear, asking you to read and
acknowledge important information regarding the proper use of electronic charts.
To acknowledge the mariners warning:
1. Press the
T
key.
A message alert and prompt will also appear asking you to select an initialization
method.
To view a message:
1. Press the
J
key.
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 mariners warning before
starting navigation. Remember that the
electronic chart is designed as a supple-
ment to local government charts, not as a
replacement.
AB

The select initialization window will appear, with the select from map option
highlighted.
1. Press
T
to initialize the receiver from the built-in worldwide map.
The Map Page will appear, prompting you to select your approximate present posi-
tion with the map cursor.
1. Use the
R
keypad to move the map cursor to a location close to your present position. If you
have difficulty identifying your exact position, press the Ckey to zoom in to a lower map scale.
2. Press
T
to confirm your selection.
The GPSMAP 180 will now begin searching for the appropriate satellites for your
present position and should acquire a fix within a few minutes. While the receiver
searches for satellites, a flashing satellite icon will appear at the left-hand side of the
status bar. A signal strength bar will appear for each satellite in view, with the appro-
priate 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 flash-
ing satellite icon on the status bar will quit flashing and remain solid, and the
GPSMAP 180 is ready for use.
Now that the unit is initialized, lets turn the unit off and then begin the Getting-
Started Tour.
To turn the GPSMAP 180 off:
1. Press and hold the
P
key for about 3 seconds, until the screen is blank.

GPSMAP 180 Getting-Started Tour
The GARMIN GPSMAP 180 is a powerful electronic charting/navigating system
that provides detailed chart coverage and convenient control of many advanced
features right from the map 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 sec-
tion for instructions on performing specific 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 descrip-
tions and pictures in the tour may not match your configuration.
To turn the GPSMAP 180 on:
1. Press and hold the
P
key until the power tone sounds. The welcome page will appear
while the unit conducts a self test.
2. Once the self test is complete, press the
T
key to acknowledge the mariners warning.
The Satellite Page will appear, and the receiver will begin to acquire satellites.
From the Satellite Page, you may also quickly adjust the screen contrast and back-
lighting.
To adjust the screen contrast:
1. To increase the screen contrast, press the right arrow of the
R
keypad.
2. To decrease the screen contrast, press the left arrow of the
R
keypad.
3. Press the
T
key to finish.
The GPSMAP 180s three-level screen backlighting is controlled with
P
key,
and may be adjusted at any time from any page.
To turn on and adjust the backlighting:
1. Press the
P
repeatedly until the backlighting is at the desired level (off, 1, 2, or 3).

The GPSMAP 180s Satellite Page provides a visual reference of satellite acquisi-
tion and receiver status, with a signal strength bar graph and a satellite sky view in
the center of the page. Each page of the GPSMAP 180s system also features an
options page, which gives you access to other functions and features that relate to
the specific page you are viewing. To get a feel for how the options pages work,
lets put the GPSMAP 180 into simulator mode.
To place the GPSMAP 180 in simulator mode:
1. From the Satellite Page, press the
O
key. The options page will appear, displaying a
menu of options and functions for the Satellite Page.

Page Sequence & Position Page
The Satellite Page is one of four main pages used in the GPSMAP 180s system.
All four 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, lets move on to the next page, the Position Page.
To scroll to the next page in sequence:
1. Press the
J
key.
The GPSMAP 180s Position Page shows where you are, what direction youre
heading and how fast youre going. The compass tape at the top of the page indi-
cates the direction youre moving. The four user-selectable data fields below the
compass tape show your current course and speed over ground, along with a
resettable trip odometer and altitude display. Your current latitude and longitude,
along with a 12/24-hour clock, appear at the bottom of the page.
Now that youve seen how the Satellite and Position Pages can be used to moni-
tor satellite acquisition and your present position, lets take a minute to learn how
to mark and store our present position as a waypoint. (Since we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 180s
R
keypad and
T
key
are used for data entry.

To mark your present position:
1. Press the
M
key. The mark position page will appear, with a default three-digit way-
point name and symbol.
2. Use the
R
keypad to highlight the waypoint name field (001) and press
T
.
3. Press the LEFT ARROW of the
R
keypad to clear the name field.
4. Use the
R
keypad to enter the name DOCK, using the UP and DOWN arrows to select
each letter, and the RIGHT arrow key to advance to the next character position. If you
make a mistake and select an incorrect character, simply use the LEFT arrow key of the
R
keypad to backspace the cursor and correct the entry.
5. Press
T
to confirm the name.
6. The field highlight will advance to the symbol field. Press
T
to access the waypoint
symbol page.
7. Use the
R
keypad to highlight the ANCHOR symbol.
8. Press
T
to confirm the symbol.
9. Press
T
again to confirm the DONE? prompt and save the waypoint.
The waypoint is now stored in memory. Note that waypoints may also be creat-
ed directly from the map display or by manually entering position coordinates.
Both of these techniques are described in the reference section of the manual
and/or on your GPSMAP 180 quick reference guide. To continue our tour, lets
move on to the Map Page.
1. Press the
J
key.

Marking A Position
A. The mark position page will automatically
assign a default three-digit name for each
waypoint, which can be changed at any time
to an alphanumeric name containing up to
six-characters.
B. A complete set of waypoint symbols allows
you to mark inland and offshore waypoints
with a custom icon for fast waypoint recogni-
tion.

The GPSMAP 180s Map Page combines digital chartplotting with a user-selec-
table display of navigation data and a built-in worldwide database to 64 nm. 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, located in the middle of the page, shows your boat as a trian-
gle marker on an electronically generated chart, along with geographic names,
markers and buoys that are provided by the G-chart cartridge youre currently
using. 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 posi-
tion, and perform various waypoint and route functions.
The data window, located at the top of the page, provides a user-selectable dis-
play of various navigation data, including course, speed over ground, and the
bearing and distance to the cursor or a particular waypoint. The status bar, located
at the bottom of the page, displays the current map scale setting, as well as the sta-
tus information described on page 29.

Map Page
A. To select an on-screen waypoint, simply move
the cursor over the desired waypoint. The way-
point/navaid name and position, along with the
bearing and distance from your present posi-
tion, will be displayed.
B. The map page can also be configured to display
additional data fields and a graphic course devi-
ation scale or compass. See page 26 for more on
map options.

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 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 DOWN arrow of the
R
keypad to move the cursor down to the first lat/lon grid
south of your boats 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, youll see that the map display
actively scrolls or pans, letting you explore areas around the world (even outside
of your current G-chart
TM
coverage) and create waypoints and routes. Wherever you
move the cursor, pressing
Q
once will return the map to your present position.
Now that you have a feel for how the cursor works, lets move on and see how the
GPSMAP 180 works on the water. To help you practice using the Map Page and
other features, weve stored a practice route in the receivers permanent memory, so
you can see exactly what youll experience when youre navigating with your new
GPS chartplotter.
