Getting Started with your GPS
Welcome to the exciting world of GARMINGPS! The
GPS 45XL represents GARMIN’s continuing commitment to
provide marine users with quality navigation information in
a versatile, user-friendly design they will enjoy for years to
come. To get the most out of your GPS receiver, be sure to
read through the initialization and Getting-Started sections
of this manual, and refer to the reference section for com-
plete details on the GPS 45XL’s advanced features.
Initializing Your GPS for First-Time Use
The GPS 45XL calculates your position and movement
by tracking signals sent from GPS satellites. Each of the 24
GPS satellites circle the earth twice a day in a very precise
orbit, and transmit information back to earth. In order to
determine a position fix, your GPS 45XL needs to continu-
ously “see” at least three satellites.
Because a GPS receiver can only see satellites above the
horizon, it needs to know what satellites to look for at any
given time. By using an almanac (a timetable of satellite
numbers and their orbits) stored in the receiver’s memory,
the GPS 45XL can determine the distance and position of
any GPS satellite.
To use this almanac data, your GPS receiver needs to
know where you are, or be given the opportunity to “find
itself”. Once you initialize the unit to this position, the GPS
45XL will usually compute a fix within a few minutes.
Remember, this process is only necessary under the
following conditions:
• First time use from the factory.
•The receiver has been moved over 500 miles from
the last calculated position with power off.
• The receiver’s memory has been cleared and all
stored data has been lost.

GPS 45XL Manual C 8/4/98 3:05 PM Page 5

Acquiring Satellite Signals
Because the GPS 45XL relies on satellite signals to pro-
vide you with navigation guidance, the receiver needs to
have an unobstructed, clear view of the sky for best perfor-
mance. What exactly does this mean? In a nutshell, the GPS
receiver’s view of the sky will generally determine how fast
you get a position fix, or if you get a fix at all. GPS signals
are relatively weak and do not travel through rocks, build-
ings, people, metal, and materials such as thick canvas, so
you need to make sure that you’re not near any of these
structures or materials when acquiring satellites.
Once the GPS 45XL has calculated a position fix, you’ll
usually have anywhere from four to eight satellites in view.
The GPS 45XL will now continuously select the best satel-
lites in view to update your position. If some of the satel-
lites in view get blocked or “shaded” the receiver can sim-
ply use an alternate satellite to maintain the position fix.
Although a GPS receiver needs four satellites to provide a
3D fix, the GPS 45XL can maintain a 2D fix with only three
satellites.
Before You Initialize
Take the GPS 45XL outside and find a large, open area
(try a nearby park) that has a clear view of the sky from
horizon to horizon. Hold the receiver at a comfortable
height, at arm’s length from your body, with the external
antenna turned perpendicular to the ground.
GPS signals are blocked from reaching the receiver
by buildings, rocks, metal structures, or materials such
as heavy canvas. Do your best to stay away from
these structures and materials.
To turn the GPS 45XL on:
1. Hold the unit so it is parallel to the ground and turn the
external antenna perpendicular to the unit.
2. Press and hold B until the receiver turns on.
The welcome page will be displayed while the unit con-
ducts a self test.

Welcome Page
GPS 45XL Manual C 8/4/98 3:05 PM Page 6

Once testing is complete, the welcome page will be
replaced by the status page, with the EZinit prompt ready
for you to select one of two initialization methods:
•Select Country––allows you to initialize the receiver
by selecting your present position from a list of coun-
tries in the GPS 45XL’s internal database. This usually
provides a position fix in 3-5 minutes.
•AutoLocateTM ––allows the GPS 45XL to initialize
itself and calculate a position fix without knowing
your present position. This usually provides a position
fix in 7.5-15 minutes.
If the EZinit prompt has not automatically appeared
on the status page:
1. Press the
E
key.
If you’ve already initialized the GPS 45XL and the
EZinit prompt appears, highlight the ‘no re-init’ selection
with the arrow keypad and press ENTER. The EZinit
prompt may appear if you’ve had the unit on in normal
mode while indoors, or if the antenna is shaded while
acquiring satellites in normal or battery saver mode.
To initialize the receiver:
1. If the ‘country’ option is not highlighted, press theDkey
repeatedly to move the field highlight to the ‘country’
option.
2. Press the
E
key.
3. Use the Dkey to scroll through the list options until the
country of your present position appears.
4. Use theUkey to highlight the country/state/region
you’re in. If the country you’re in is not listed, select anoth-
er country within 500 miles of your present position.
5. Press
E
to finish.
The GPS 45XL will now begin searching for the appro-
priate satellites for your position and should acquire a fix
within 3-5 minutes. You can verify that you have acquired a
fix by watching the status page transition to the position
page (provided you haven’t pressed any other buttons) or
looking for a 2D or 3DNAV status at the top left corner of
the status page.

The EZinit prompt will
automatically appear if the
receiver needs to be initial-
ized. The prompt may also
appear during normal use if
the antenna is shaded or the
unit is indoors.
Use the arrow keypad to
highlight the country and
region or state (if neces-
sary) of your present posi-
tion from the list and press
ENTER. If the country is
not listed, select the closest
country instead.
GPS 45XL Manual C 8/4/98 3:05 PM Page 7

To prevent accidental battery power loss, the GPS 45XL
will automatically shut off 10 minutes after the last key-
stroke if the unit is not tracking at least one satellite and
has never acquired a position fix.
If you have trouble initializing the receiver or getting a
position fix, check the following:
•Does the receiver have a clear view of the sky?
If there are large buildings, rocks, or mountains, if there
is heavy tree cover, the receiver may not be receiving
enough satellite signals to calculate a fix.
•Have you selected the right country/state/region
from the EZinit list?
Check for the correct approximate lat/lon on the posi-
tion page or reselect the appropriate country from the
list to restart the initialization.
•Have you moved more than 500 miles from the last
calculated position with the receiver off?
Reinitialize the receiver, selecting the country/state/
region of your new location from the EZinit list.
External Antenna
The GPS 45XL’s antenna may be removed to attach an
optional external antenna or automobile antenna.
To remove the attached antenna:
1. Rotate the knurled knob (located at the bottom left of the
antenna) toward the front of the unit one-quarter turn.
2. Pull the antenna gently away from the unit.
3. To install the antenna lead, mate the BNC connector
notches with the mounting posts and turn the knurled knob
one-quarter turn toward the back of the unit.

Getting-Started Tour
Now that your GPS receiver has been initialized, it’s
time to take a tour through its basic features and functions.
The tour assumes that you have initialized the receiver and
have not changed any of the factory settings (units of mea-
sure, selectable fields, etc.). If you have changed any of the
default settings, the pictures and descriptions may not
match your unit’s configuration.
Powering Up and Taking a Fix
Take the GPS 45XL outside and find an open area
where the receiver will have a clear view of the sky. Hold
the receiver at a comfortable height, at arm’s length from
your body, with the external antenna turned perpendicular
to the receiver.
To turn the unit on:
1. Press and hold
B
until the receiver turns on.
A welcome page will be displayed while the unit con-
ducts a self test. Once testing is complete, the welcome
page will be replaced by the satellite status page and the
GPS 45XL will begin acquiring satellites.
Satellite Status Page
The GPS 45XL’s satellite status page provides a visual
reference of satellite acquisition and position. As the receiv-
er locks onto satellites, a signal strength bar will appear for
each satellite in view, with the appropriate satellite number
(1-32) underneath each bar. The progress of satellite acqui-
sition is shown in three stages:
•No signal strength bars— the GPS 45XL is look-
ing for the satellites indicated.
•Hollow signal strength bars— the GPS 45XL has
found the satellite(s) and is collecting data.
•Solid signal strength bars— the GPS 45XL has
collected the necessary data and the satellite(s) is
ready for use.
Note that each satellite has a 30-second data transmis-
sion that must be collected (hollow bar status) before the
satellite may be used for navigation (solid bar status). Once
a fix has been calculated, the GPS 45XL will then update
your position, track and speed by selecting and using the
best satellites in view.

GPS 45XL Manual C 8/4/98 3:05 PM Page 9

The satellite sky view shows a bird’s-eye view of the
position of each satellite relative to the unit’s last known
position. The outer circle represents the horizon (north up);
the inner circle 45º above the horizon; and the center point
directly overhead. You can use the sky view to help deter-
mine if any satellites are being blocked, and whether you
have a current position fix (indicated by a ‘2D NAV’ or ‘3D
NAV’ in the status field.
Once sufficient signals have been acquired, the status
page will be replaced with the position page, provided you
have not pressed any other buttons.
Position Page
The second page in the GPS 45XL’s main page sequence
is the position page. The position page shows you where
you are, what direction you’re heading and how fast you’re
going, and is particularly helpful when you do not have an
active destination selected. The graphic display at the top of
the page indicates your cardinal heading (while you’re mov-
ing) with the track and speed indicated below.
The graphic compass display is designed to show
your current track and does not serve as a true
magnetic compass while you’re standing still.
The rest of the page shows your current position in
three dimensions: latitude, longitude and altitude. The
GPS 45XL uses this basic information to mark exact posi-
tions as waypoints, which help guide you from one place to
another. A trip odometer and 12/24 hour clock are also
provided.

Marking a Position
Now that you’ve acquired a position, let’s mark it as a
waypoint for future reference.
1. Press the
M
key to capture and hold your position.
To mark a position, you must have obtained a 2D or
3D fix, or have the receiver in simulator mode. If
you try to mark a position without a position fix, you
will be alerted with a ‘No GPS Position’ message.
The mark position page will appear, showing the cap-
tured position and a default 3-digit waypoint name. Let’s
change the default name to something a little more mean-
ingful, like ‘HOME’.
1. Press the U key twice to move the field highlight from
the ‘save’ field to the name field.
2. Press
E
and L to clear the default waypoint name.
3. Press and hold the U key to scroll through the alphabet
until the letter ‘H’ appears.
4. Press the R key once to move the character highlight to
the next character space.
5. Repeat steps 3 and 4 until the word ‘HOME’ is displayed.
6. Press
E
to complete entry of the name.
7. Press the
D
key once to return the field highlight to the
‘save’ field.
8. Press the
E
key to confirm that you want to save the
position as a waypoint named ‘HOME’.
The mark position page will now be replaced by the
position page (the page displayed prior to pressing the
M
key). The ‘HOME’ waypoint is now stored in the GPS
45XL’s memory, and will remain there until you manually
remove it or clear the receiver’s memory. For more on way-
point management, see pages 21-27.

Using the Position and Map Pages
Now that you’ve marked a position, it’s time to take a
brisk walk using the position and moving map pages to
watch your every move. To get the most from this tutorial,
you will need to walk for at least the time stated in the
below steps. Since the GPS system has a margin of error of
15 meters, this will ensure you travel far enough to register
useful information. You’ll also get a much better indication
of how the GPS 45XL’s steering guidance and mapping
features work to guide you wherever you go.
1. Walk in a straight line for 3-4 minutes at a fast pace and
watch the position page. You can time your distance with
the on-screen clock.
The direction you are moving (your track) and your
speed are displayed on the upper part of the screen, just
below the graphic compass display. The latitude, longitude
and approximate altitude of your position--along with a
resettable trip odometer--are continuously displayed in the
middle of the page, with the time of day displayed below.
Now let’s change the display to the moving map page
and watch the track log of our walk:
1. Press the
P
key to change from the position page to
the map page.
Your current position is shown as the diamond in the
middle of the screen. The dark circle below the diamond
represents the position you created, with the line between
the two showing your track.
1. Now turn 90º to your right and continue walking at a fast
pace for another 2-3 minutes. Notice how the display
changes, always keeping the direction you are moving at
the top of the map.

Going To a Waypoint
Once you’ve stored a waypoint in memory, you can use
the GPS 45XL to guide you to it by performing a simple
GOTO. A GOTO is really nothing more than the receiver
drawing a straight-line course from your present position to
the destination you’ve selected. To see how it works, let’s
try navigating back to our starting position, the HOME
waypoint.
To select a GOTO destination:
1. Press the
G
key.
2. The GOTO waypoint page will appear, displaying all the
waypoints in memory in alphabetical order.
3. Use U or D to highlight the ‘HOME’ waypoint.
4. Press the
E
key to confirm that you want to navigate
to the displayed waypoint.
The GPS 45XL’s highway page also provides graphic
steering guidance to a destination, with an emphasis on a
straight line course to the desired waypoint and the dis-
tance and direction you are off course. The bearing and dis-
tance to a waypoint, along with your current track and
speed are displayed at the top of the screen, with your esti-
mated time enroute (ETE) and velocity made good (VMG),
or the rate you are closing in on your destination shown at
the bottom.

Using the Highway Page (continued)
As you head toward your destination, the middle sec-
tion of the screen provides visual guidance to your way-
point on a moving graphic ‘highway’. The moving arrow
just below the course deviation scale always points to your
selected waypoint relative to the direction you are moving.
Your present position is represented by the diamond in
the center of the course deviation scale. The line down the
middle of the highway represents your desired track. As
you navigate toward a waypoint, the highway will actually
move, indicating the direction you’re off course, relative to
the position diamond on the CDI scale. To stay on course,
simply steer toward the center of the highway.
While navigating, you may decide to view the compass
page (see picture above left) instead of the highway page.
To select the compass page:
1. While viewing the highway page press
E
twice.
The compass page will now become the displayed navi-
gation page. This page provides a directional pointer to
your destination, by using a rotating compass display to
show direction of travel. It provides better steering guid-
ance at slower speeds for travel with many directional
changes.
To switch back to the highway page, press ENTER
twice, again.

Scrolling Through the Main Pages
Now that you’ve arrived ‘HOME’, let’s take a minute to
see how the GPS 45XL’s main pages work together. The GPS
45XL features five main pages, which are linked together in a
chain. You can quickly scroll through the pages in either
direction using the
P
and
Q
keys.
1. Press the
P
key to scroll through the five main pages
in sequence.
2. Press the
Q
key to scroll through pages in the oppo-
site direction.
Menu Page
You’ve already seen the first four pages in action by
acquiring satellites, marking a position and navigating to a
destination. The last page available from the main page
sequence is the menu page, which provides access to the
GPS 45XL’s waypoint management, route, track log and
setup features. The 11 submenus are divided into categories
by function.
To select a submenu from the menu page:
1. Press
P
or
Q
until the menu page appears.
2. Use the U or D keys to highlight the submenu you
want to view.
3. Press

Clearing the Track Log
After you’ve used the GPS45XL for a few trips, you
may find that your map display has become a bit messy
from keeping track of your every move. To get a feel for
how the menu page works, let’s clear the track log (the plot
points left on the map page) we’ve just created during the
Getting Started tour.
1. Press
P
or
Q
until the menu page appears.
2. Use the D key to move the field highlight to the
‘TRACKLOG’ option.
3. Press
E
to access the track log page.
4. Press the U key twice to highlight the ‘CLEARLOG?’
option. The clear log confirmation page will appear.
5. Use the L key to highlight the ‘Yes’ prompt.
6. Press
E
to finish.
Turning the Receiver Off
You’ve now gone through the basic operation of your
new GPS receiver and probably know a little more than you
think about how it works. We encourage you to experiment
with the GPS 45XL until it becomes an extension of your
own navigation skills. If you encounter any problems using
the unit or want to take advantage of the GPS 45XL’s more
advanced features, refer to the reference section.
To turn the GPS 45XL off:
1. Press and hold the
B
key for 3 seconds.
