The GPSMAP system is designed as an aid to
navigation, and is not intended to replace the
use of government-approved charts and tradi-
tional navigation practices. Make sure you
read and understand the mariner’s acknowl-
edgement before using the unit.
1
The GARMIN GPSMAP is a powerful electronic charting/navigating system
that provides detailed chart coverage and convenient control of many
advanced features right from the graphic charting page. This tour is designed
to take you through the basic pages and functions of the GPSMAP system.
Once you’re familiar with the main pages and functions of the unit, refer to the
reference section for instructions on performing specific tasks and functions.
Before beginning the GPSMAP tour, make sure the main unit and antenna
have been properly installed (see Appendices A & B). Note that our tour will
use the GPSMAP’s built-in worldwide database and the simulator mode, so you
won’t have to install a chart cartridge or acquire satellites for this exercise. The
tour assumes you have not changed any of the default settings for the unit. If
you have changed any settings (position formats, units of measure, etc.), the
descriptions and pictures in the tour may not match your configuration.
Powering Up and Starting the GPSMAP Tour
The GPSMAP’s power and screen backlighting are controlled by the J
key at the bottom left of the unit. To turn the GPSMAP on:
1. Press and hold the right side of the Jkey until the power tone sounds.
2. Once the welcome page appears, press the Ckey to acknowledge the
mariner’s warning notice and begin operation.
To adjust the screen backlighting level:
1. To increase the brightness level, press and release the right side of the
Jkey.
2. To decrease the brightness level, press and release the left side of the
Jkey.

The GPSMAP system does not actively track
satellites in the simulator mode. Never use the
simulator mode for actual navigation. Any
waypoints, routes and track logs you create
while simulating navigation will be saved in
memory, and are available for use when using
the unit in normal operating mode.
2
Once you’ve acknowledged the mariner’s warning, the Satellite Status Page
will appear. The Satellite Status Page provides a visual reference of satellite
acquisition and status, with a signal strength bar graph and satellite sky view
in the center of the screen. The status field at the top left of the screen indi-
cates the unit’s operating mode, with current GPS accuracy displayed below.
Across the bottom of the screen, you’ll find five on-screen menu buttons
called ‘softkeys’. Each softkey corresponds to the Mkey directly below it,
and provides access to various route, waypoint and auxiliary functions. To see
how softkeys work, let’s put the GPSMAP in simulator mode:
1. Press the AUX softkey to display the Auxiliary Menu.
The Auxiliary Options Menu will appear, with the System Setup option
highlighted. At the bottom of the screen, you’ll notice a prompt field that pro-
vides you with instructions to help you through operating procedures.
1. With the System Setup option highlighted, press the Ckey.
2. The System Setup Menu will appear. Highlight the Operational Mode field,
using the Kkeypad, and press Cto see the available options.
3. Use the Kkeypad to highlight ‘Simulator’ and press Cto accept.
4. Press Cto acknowledge the simulator warning notice.
5. Press the EXIT softkey to return to the Auxiliary Options menu.
6. Press the EXIT softkey again to return to the Satellite Status Page.
Your GPSMAP is now in simulator mode.

Use the KKEYPAD to choose letters,
numbers, spaces and symbols in a data field.
Only the appropriate characters will be
available for a particular data entry window.
3
Now that you are back at the Satellite Status Page, let’s enter a starting posi-
tion for our tour. Entering names and numbers in the GPSMAP system is done
through data entry windows. Once a data entry window is open, the K
keypad and Ckey are used to choose and accept a value for each character
position:
1. Press the Kkey to highlight the position field (top right).
2. Press the Ckey to begin entry of the following position:
N 24º 43.111’, W 077º 42.407’.
3. Use the Kkeypad to highlight the appropriate character choice for each field.
4. Press the Ckey to accept each choice and move to the next character posi-
tion. When you accept a value for the last character position, you will
automatically return to the Satellite Status Page.
If you need to correct a mistake or change values in a character field, use the appro-
priate softkeys at the bottom of the screen. Use BKSPC to move back one character
position; CLEAR to erase all entered data; and RESTORE to restore the previous field
value. The OK softkey accepts data entry and returns the display to the previous
page, and the CANCEL softkey stops the current data entry mode.
The Satellite Status Page will now indicate the position you entered and give
you a simulated display of signal strength and satellite position. To continue
the tour, let’s move on to the Map Page.
1. Press the Ekey to display the Map Page.

215225manb.qxd 4/27/00 9:22 AM Page 3

The Data Window (at the right side of the
screen) and the Softkey Menu Display (at the
bottom of the screen) may be turned off for a
full page display of cartography:
• To turn the Data Window off, press B.
• To turn the Softkey Menu off, press G.
4
The GPSMAP system is built around a powerful graphical Map Page. The
Map Page combines digital electronic charting with a complete display of
important navigational data and easy access to advanced features. After
completing the tour, you’ll be able to perform most navigation, waypoint and
route functions directly from the Map Page. Before we start creating waypoints
and routes, let’s take a brief look at its various features and displays.
The Map Page can be broken down into three main sections: map display,
data window and softkey menu.
The map display shows your boat as a wedge icon on an electronically
generated chart, complete with geographic names, markers, buoys and depth
contours. It also displays your track, routes and nearby waypoints. An
on-screen target cursor lets you pan to other map areas, determine the range
and bearing to a position and perform various route and waypoint functions.
The data window provides a digital display of navigation data, in relation
to your present position, the target cursor position or a particular waypoint.

The destination field, located at the top of the data window, shows your
bearing (BRG) and distance (DIS) to a destination waypoint or to the cursor. It
also displays your crosstrack error (XTK) and turn (TRN) heading to an active
destination. The XTK value is the distance you are off a desired course (left or
right), while TRN represents the direction (left or right) in degrees between
your course over ground (COG) and the bearing to your destination.
The speed and course field, located
below the destination field, displays your
present speed and course over ground
(SOG and COG).
Below the speed and course field are the
arrival and status fields. The arrival field
displays your velocity made good (VMG)
and estimated time enroute (ETE). Your
velocity made good is the speed you are
closing in on a destination along your
desired track, while the ETE represents the
total time left to reach your destination
based on your current VMG.
The status field indicates the operating
mode and map scale currently in use.
The map scale represents the approximate
distance from the top of the map display
to the bottom.
The softkey menu provides you with direct access to the GPSMAP’s route,
waypoint, auxiliary and range/bearing calculation functions.

As you move the cursor, the distance and
bearing from your present position to the
cursor will be displayed in the destination
field (at the top right of the screen).
The cursor’s position coordinates will be dis-
played in the position field (below the speed
and course field).
While in cursor mode, the boat icon will
continue to move, and may go off screen to
accommodate the scrolling cursor.
6
Using 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 as a distance and bearing marker, to create new waypoints and
routes, and to review position data of on-screen waypoints, buoys and
markers. Try moving the cursor using the following exercise:
1. Use the Lkey to set the map scale to 64 n.m.
2. Your boat should be in the center of the map display, near Andros Island and
Nassau (the position you entered earlier).
3. Press the bottom arrow of the Kkeypad to move the cursor down to the first
lat/lon grid South of your boat’s position.
4. Using the Kkeypad to move the target crosshair in each direction, try follow-
ing the outline of the lat/lon grid closest to your boat. Notice how the
destination field of the data window displays the distance and bearing from
your position to the target cursor, with the cursor’s coordinate position
indicated in the position field.
5. Press the Akey to eliminate the cursor and re-center your position on the
map display.
As you become more familiar with using the cursor, you’ll see that the map
display actively scrolls forward with your panning, letting you explore areas
around the world (even outside of your current G-chartTM coverage) and create
waypoints and routes. Wherever you move the cursor, you’ll always be one
Akeystroke away from returning to your present position.
GPSMAP TOUR
Using the Target Cursor
215225manb.qxd 4/27/00 9:22 AM Page 6

The GPSMAP system stores over 1900
alphanumeric waypoints, with selectable
graphic icons and a user-defined comment
field. If you mark a navaid position that
appears on a G-chart electronic cartridge,
the default comment will automatically select
the navaid text associated with the marker.
7
To continue the tour, let’s mark our simulated present position for reference:
1. Press the Fkey to capture your present position as a waypoint.
The Mark GPS Position window will appear, with a default three-digit
waypoint name and symbol. By pressing the Ckey, you can confirm the
waypoint with the default name and symbol, but let’s change the name and
symbol to something a little more meaningful:
1. Use the Kkeypad to move the field highlight to the ‘Wpt’ field and press C.
2. Enter the name ‘DAY1’ with the Kkeypad, pressing Cafter each character.
3. After you’ve entered the last letter, press the OK softkey to confirm the name.
4. The field highlight will move to the waypoint symbol field. Press Cto begin
selection of a new waypoint symbol.
5. Use the Kkeypad to highlight the fish symbol (on the second line of the
window) and press the Ckey.
6. The field highlight will move to the comment field, where you may enter a 20-
character comment (the default comment is the date and time of creation).
7. Press Cto begin entry of a comment.
8. Use the Kkeypad to enter ‘TOUR’ in the comment field, pressing the Ckey
after each character.
9. Press the OK softkey to accept your comment.
10. Use the Kkeypad to highlight the OK field.
11. Press the Ckey to save your new waypoint.
GPSMAP TOUR
Marking a Position
215225manb.qxd 4/27/00 9:22 AM Page 7

Whenever the cursor comes in close proximity
to an on-screen waypoint or navaid, it will
‘snap’ to and highlight its on-screen icon.
Once an on-screen marker has been high-
lighted, destination and position information
will be displayed in the data window.
This feature makes it easy to review waypoint
positions right from the map display.
8
Now that you’ve marked a waypoint for your starting position, let’s make a
route to navigate using the ROUTES softkey. (For the purposes of this tour,
make sure that the current map scale is still at 64 n.m.)
1. Press the ROUTES softkey to begin creating a route.
2. Use the Kkeypad to highlight the Route 1 field and press C.
The GPSMAP system can store 20 reversible routes of up to 50 waypoints each.
Routes 1-19 are used as storage routes, with Route 0 always serving as the active
route. Although you may create a route in the Route 0 position, be aware that it will
automatically become the active route upon completion. If you want to save a route
created in the Route 0 position, be sure to copy it to another storage route, as it will
be overwritten by the next route activation (see Section 8 for more details on routes).
As the GPSMAP returns to the Map Page, you’ll notice several changes. The
map display will now show the cursor as an arrow at your present position,
with the prompt field indicating instructions for adding waypoints to your
route. To select the DAY1 waypoint as your first route waypoint:
1. Press the Ckey to add the waypoint to the route.
Now add the next waypoint to the route:
1. Use the Kkeypad to move the arrow cursor as close as possible to the
following coordinates: N 24º 27.371’, W 077º 42.407’.
2. Press Cto save the waypoint position.
3. Press Cto confirm the default waypoint name, symbol and comment.

Now add the final waypoint to the route:
1. Use the Kkeypad to move the arrow cursor as close as possible to the
following coordinates: N24º21.777’, W077º51.424.
2. Press the Ckey to save the waypoint position.
3. Press Cto confirm the default waypoint name, symbol and comment.
We now have a three waypoint route from our present position to
waypoint 002. To activate the route and begin navigation:
1. Press the EXIT softkey to quit the route creation mode.
2. Press the ACTIVTE softkey.
The GPSMAP will return to the Map Page, with your active route (Route 0)
shown on the map display and the ‘active to’ waypoint (001) displayed in the
destination field. The speed and course field tells us we’re getting nowhere
fast, so let’s go to the Highway Page and enter a speed for our simulated trip:
1. Press the Ikey to display the Highway Page.
The Highway Page provides you with a large, digital display of navigation
data and graphic steering guidance to an active destination via a three-dimen-
sional perspective of your course. As you head toward your destination, the
middle of the screen provides visual guidance on a moving “graphic” highway.
Your present position is at the bottom 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.

The Simulator SOG/COG window lets you
specify the speed and course for the simulator
mode. By leaving the COG field value at
the default setting, the GPSMAP system will
automatically set a course directly to your
destination.
If you choose to enter your own course over
ground, highlight the COG field and enter
the desired course. To reset the simulator to
steer a direct course for you, highlight the
‘Reset COG to Nav Course’ prompt and
press the Ckey.

The active destination waypoint is displayed at the top of the screen, with
the ETE (estimated time enroute) and ETA (estimated time of arrival) based on
your present speed and course at the bottom.
The distance and bearing to the first route waypoint, along with your cur-
rent speed and course over ground (SOG and COG), are indicated along the
right-hand side of the screen. The SOG and COG fields can be changed to
display velocity made good (VMG) and turn (TRN). To toggle the speed and
course displays, press the Bkey.
Now enter a speed of 60 knots for our simulated trip:
1. Press the SOG/COG softkey to display the Simulator SOG/COG window.
2. Press the Ckey to begin data entry.
3. Use the Kkeypad to enter a speed of 60 knots, pressing the Ckey after
each character entry.
4. Once you’ve entered your speed, press the EXIT softkey.
By leaving the COG field value at the default setting, the GPSMAP system
will automatically set a direct course to each route waypoint. If you choose to
enter your own course, highlight the COG field and enter the desired course.
To reset the simulator to automatically steer a direct course for you, highlight
the ‘Reset COG to Nav Course’ prompt and press the Ckey.
At the bottom right corner of the highway display is the highway scale. The
highway scale ranges from ‘1X’ to ‘16X’, and allows you to change the
perspective view of the highway to show a larger or smaller area.
1. Press the down arrow on Lto decrease the scale and show a smaller area.
2. Press the up arrow on Lto increase the scale and show a larger area.
