Introduction
Maintenance
GPS CLEANING
The eTrex is constructed of high quality materials and does not require user maintenance other than cleaning.
Clean the unit using a cloth dampened with a mild detergent solution and then wipe dry. Avoid chemical cleaners
and solvents that may damage plastic components.
LENS CLEANING
The eTrex lens is sensitive to skin oils, waxes and abrasive cleaners. It is very important to clean the lens using
an eyeglass lens cleaner and a clean, lint free cloth.
STORAGE
Storing alkaline batteries in the unit for long periods of time is not recommended. In order to reduce the
chance for battery leakage in the battery compartment, remove the batteries when storing the unit for more than
six months.
Do not store the eTrex where prolonged exposure to temperature extremes may occur (such as in the trunk of
a car) as permanent damage may result. User information, such as waypoints, routes, etc. will be retained in the
unit’s memory without the need for external power. It is always a good practice to back up important user data by
manually recording it or downloading it to a PC (transferring it to MapSource).
WATER IMMERSION
The eTrex is waterproof to IEC Standard 60529 IPX7. It can withstand immersion in 1 meter of water for 30
minutes. Prolonged submersion can cause damage to the unit. After submersion, be certain to remove the batteries and dry the compartment before reuse.
Remove the batteries from your eTrex if you don’t
expect to use it for several months. Be sure to observe
the proper polarity when inserting the batteries.
Follow the battery manufacturer’s instructions on the
proper care and handling of the batteries.
viii
The eTrex is a six ounce, 12-channel, handheld GPS receiver. It has a built-in GPS
antenna and five user-buttons. All buttons are located on either side of the unit, allowing for
simple, one-handed operation that won’t obstruct your view of the display. It runs for up to
16 hours on two AA batteries during typical use and up to 22 hours in battery save mode.
In addition to determining your location, the eTrex can create, name, and save locations
in internal memory as electronic waypoints, allowing you to navigate back to those points
any time you want. And once you start moving, the GPS provides additional data, such as
speed, direction of movement, time and distance to your destination, and more.
Introduction

Getting Started
The Getting Started Section of this manual introduces you to the basic operation of the
eTrex. eTrex features are described in more detail in the Reference Section.
The First Step
Getting Started
Here We Go
The eTrex’s GPS operates using information gathered from satellites. To initialize the unit’s
GPS receiver for the first time, take your eTrex outside and find a large, open area that has a
clear view of the sky. Press and hold the POWER button to turn the unit on. The Welcome
Page appears for a few seconds, followed by the SkyView Page.

NOTE: When you use the eTrex for the first time, it may take up to five minutes
to find your location. After the first use, eTrex only needs about 15 to 45 seconds
to find your location.
The SkyView Page
The eTrex needs to receive at least three strong satellite signals to find your location. The
SkyView Page shows you a graphic representation of the satellites being tracked and the
strength of the satellite signals. A status message is displayed at the top of the page.
When you see the “READY TO NAVIGATE” message in the status box, eTrex has found
your location and the GPS receiver is initialized and ready for use.
Backlighting and Contrast
If lighting conditions make it hard for you to see the screen, adjust the contrast or turn on
the backlight. Press and release the POWER button from any screen to turn on the backlight.
By default, the backlight is timed to stay on for 30 seconds. To adjust the screen contrast,
press the PAGE button until you see the SkyView Page. Press and hold the UP button to
make the screen darker; press and hold the DOWN button to make the screen lighter.
The “READY TO NAVIGATE” message
must appear before you can begin using
your eTrex to navigate.

SkyView Page Basics
The SkyView Page displays the eTrex’s receiver status. It also shows the strength of the
satellite signals that are being received. If the signals are weak you may need to try a different
location for better reception. The shorter the signal strength bar, the weaker the signal. At the
top of the page the unit displays the status of the receiver. The eTrex displays the message
‘Ready to Navigate’ when the receiver has gathered enough satellite information to begin
navigation.
The page defaults to the Basic SkyView. To change to Advanced SkyView, press the

The Map Page shows where you (the animated figure) are located and provides a picture
of where you are going. As you travel, the animated figure “walks” and leaves a “breadcrumb
trail” known as a Track Log. The map also shows waypoint names and symbols.
On the Map Page, the UP and
DOWN buttons are used to
adjust the map scale from 200
feet to 800 miles.
To help you better visualize the “real world,” eTrex is set to automatically rotate the map
as you move, so that waypoints that are ahead of you are always displayed in front of the
animated figure. In the upper left corner of the screen, the Map Orientation is displayed. For
information on changing the Map Orientation, see page 13.
To make sure you can see your entire trip, you can change the map scale from 200 feet to
800 miles. To increase the map scale, press the UP button. This lets you view a larger area
in less detail. To decrease the map scale, press the DOWN button. This shows a smaller area
with more detail.

Routes Page
Menu Page
The eTrex allows you to navigate using one of three methods: GOTO (discussed on pages
9–10 and 22), TracBack (discussed on page 30), and routes.
Routes Page
A route is a path of travel between two or more waypoints. The route feature allows the
eTrex to guide you from the first waypoint in the route to each successive waypoint until you
reach your final destination.
The route feature and the GOTO feature are comparable in that they both guide you to
destination waypoints. However, the route feature is more useful for navigating to multiple
points along a path. When you reach one waypoint, the eTrex automatically guides you to the
next waypoint along the route. When you use the ‘GOTO’ feature you have to stop and select
the next waypoint before you start moving.
When creating a route, you select waypoints from the waypoint list and place them into
a route in the sequence that you want to navigate to them. You need at least two waypoints
(up to a maximum of 125) linked together to form a route. You can create and store up to 20
individual routes in your eTrex. Your saved routes are automatically named based on the first
and last waypoints in the route. Saved routes are listed on the Routes Page, with an arrow
indicating which route (if any) is currently active.
When you start your trip, you activate the route feature and the receiver begins navigation
toward the first waypoint in the route. You can then use the Pointer Page to give you steering
guidance.
The ‘ROUTES feature is found on
the Menu Page.

Track Log Page
You need to save the Track Log first before
you can use the TracBack feature.
What is a Track Log?
The eTrex draws an electronic “breadcrumb” trail on the Map Page as you travel. This
trail is called the Track Log. The Track Log contains information about each point it plots
along the way, including time and position. After a Track Log is saved in the unit’s memory,
you can use the Track Log information to navigate. You can also review the saved Track Log
on the map and use the Track Setup page to turn recording on or off and change the way
tracks are recorded.
You can save a total of ten Track Logs in the eTrex. The Track Log starts recording as soon
as the unit gets a location fix. If you want to use the ‘TracBack’ feature (see page 30), it is
recommend that you save the current Track Log and clear it before you start traveling. The
percentage of memory used by the current Track Log is displayed at the top of the Tracks
page. After the Track Log is ‘CLEARED,’ it shows zero percent. When the display shows
99%, the most recent track points will start overwriting the beginning track points, in order
to avoid losing any track points, you should save the Track Log before it reaches 99% of
memory usage.
Saved tracks can be used for navigation later. After a Track Log is saved, the saved track
will have a beginning (BEGIN) point and an ending (END) point.
To save the current Track Log:

map datum, map units, and north reference to match the map’s units. This is the purpose
of the Units Page. Regarding position format, the eTrex allows you to choose from more
than eighteen different grids. The eTrex supports the UTM/UPS and latitude/longitude grids
because together they cover the world.
Position Format
Setup Page
The default position format (and the one most commonly used) for the eTrex is latitude
and longitude in degrees and minutes (hdddº mm.mmm). You may also choose from 17
other position formats. There is also a “User” position format which allows you to approximate custom-designed grids. For more information on grids and datums we recommend you

Map Datums
A map datum is a reference model of the earth’s shape. Every map uses a map datum.
The map datum is usually listed in the title block of the map. If you are comparing GPS
coordinates to a paper map or other reference, the map datum in the eTrex should match the
horizontal map datum used to generate the chart or other reference.
The default datum in the eTrex is WGS 84 (World Geodetic Survey, 1984). You should
only change the datum if you are using maps or charts that specify a different datum than
WGS 84. If no datum is specified, you can select each datum applicable to your region until
you find the datum that provides the best positioning at a known point. You may also choose
the “User” datum for use with custom-designed grids.
User

North Reference
You can select True North, Magnetic North, Grid
North, or User-Defined north reference grids.
36
‘Reference’ refers to the orientation of a map’s grid. Map makers try to align the vertical
lines on a map with ‘True North’ (TRUE). True North is the direction from any location on
the earth’s surface to the “North Pole.” Maps are typically referenced to true north. Because
a compass points to magnetic north, not true north, maps indicate the difference between
true and magnetic north with something called ‘variation’ or ‘declination.’ The amount of
declination changes as you move around the earth. Magnetic North (MAG) is the direction
in which a compass needle points.
The eTrex bearings will correspond to a compass if the eTrex is set to magnetic north.
Due to errors introduced when map makers flatten the earth’s sphere onto paper, not all of
the grid lines drawn on the map point exactly to the north pole, so the north indicated by
the grid lines is called ‘Grid North’ (GRID). But, the difference is usually small enough that
‘Grid’ north can be considered the same as True North for travelling on land. If necessary, you
can select a ‘User-Defined Grid’ (USER) to correct for the difference between Grid North
and True North manually.

The global positioning system is a satellite-based navigation system consisting of a network of 24 orbiting NAVSTAR satellites that are eleven thousand nautical miles in space and
in six different orbital paths. The satellites are constantly moving, making two complete orbits
around the Earth in less than 24 hours.
The orbital paths of these satellites take them between roughly 60 degrees North and 60
degrees South latitudes. What this means is you can receive satellite signals anywhere in the
world, at any time.
One of the biggest benefits over previous land-based navigation systems is GPS works in
all weather conditions. No matter what your application, when you need it the most, your
GPS receiver keeps working.
The GPS signal contains a ‘pseudo-random code,’ ephemeris (pronounced: ee-fem-er-is),
and almanac data. The pseudo-random code identifies which satellite is transmitting—in
other words, it is an I.D. code. We refer to satellites by their PRN (pseudo-random number),
from 1 through 32, and this is the number displayed on a GPS receiver to indicate which
satellite(s) we are receiving. Ephemeris data contains important information such as satellite
status (healthy or unhealthy), and the current date and time. The almanac data tells the GPS
receiver where each GPS satellite should be at any time throughout the day. Each satellite
transmits almanac data that provides orbital information for all of the satellites in the GPS
network.
Your GPS receiver reads the message and saves the ephemeris and almanac data for continual use. Now, to determine your position, the GPS receiver compares the time a satellite
signal was transmitted with the time it was received by the GPS. The time difference tells the
GPS receiver how far away that particular satellite is. If we add distance measurements from a
few more satellites, we can triangulate our position. This is exactly what a GPS receiver does.
With a minimum of three or more satellites, your GPS can determine a latitude/longitude
position—what’s called a 2D position fix. With four or more satellites, a GPS receiver can
determine a 3D position fix which includes latitude, longitude, and altitude. By continuously
updating your position, a GPS receiver can also accurately provide speed and direction of
travel (referred to as ‘ground speed’ and ‘ground track’).
Appendix B
What is GPS?

Appendix C
What is WAAS?
WAAS Capability
The eTrex is capable of receiving WAAS (Wide Area Augmentation System) satellite
signals. WAAS is an FAA (Federal Aviation Administration) funded project to improve the
overall accuracy and integrity of the GPS signal for aviation use, but land/sea based users may
also benefit from this system. There are currently two WAAS satellites that can be received
in the U.S.A., one over the Atlantic Ocean and one over the Pacific Ocean, in a geo-stationary orbit over the equator. Effective use of the WAAS satellite signal may be limited by your
geographic location in relation to those satellites. WAAS is most effective for users in the
continental U.S. WAAS satellite signal reception requires an absolute clear view of the sky and
works best when there are no nearby obstructions such as buildings or mountains. WAAS
satellites are numbered 33 or higher when viewing the sky view on your eTrex. Initial reception of the WAAS signal may take up to 15–20 minutes, then 1–2 minutes afterwards. When
WAAS differential correction has been received for GPS satellites (numbers 32 or below), a
‘D’ appears in the signal bar of the Advanced Sky View. When enough satellites have received
WAAS differential correction, ‘DIFF’ appears below the ‘Ready to Navigate’ message.
To learn more about the WAAS system, its satellite positions and current state of development, visit the FAA Web site (http://gps.faa.gov).
Since WAAS requires CPU resources of the eTrex to search for and track the satellites,
you may disable the WAAS feature to improve unit performance if WAAS reception is not
available in your area.
To disable/enable WAAS capability:
1. From the MENU Page, highlight ‘SETUP’ and press ENTER. The SETUP Page appears.
2. Press the UP or DOWN button to highlight ‘SYSTEM.’
3. Press the UP or DOWN button to highlight ‘GPS.’ Press ENTER. The Option List appears.
44
4. Press the UP or DOWN button to highlight the desired GPS mode and press ENTER.
Why won’t the eTrex power on?
Check to see if the batteries are installed correctly and that the battery terminals are clean.
Can I use the eTrex indoors?
Not for navigation, but you can edit existing waypoints and routes, and you can use the Demo
mode to practice (see page 40).
Appendix D
FAQs
Do I need to subscribe to a service to use the eTrex?
No. The GPS satellites are owned by the United States Department of Defense (DoD) and have
been funded by U.S. taxpayers’ dollars. Reception of GPS satellite signals is free to everyone.
Does the eTrex work anywhere in the world and in any weather?
Yes.
How accurate is a Garmin GPS?
The eTrex is accurate to within 15 meters. Using differential techniques (WAAS), the eTrex can
be as accurate as 1-5 meters.
Why can’t I see the display in the daylight?
Adjust the contrast (see page 1).
Why can’t I interface my computer with the eTrex?
Make sure that you have the correct INPUT/OUTPUT format selected on your eTrex.
What does the message "NO DGPS POSITION" mean?
eTrex had a differential fix and lost it.
What do I do if it takes more than 10 minutes to get a location fix?
There may be large obstacles overhead. Move to a new location with a clear view of the sky.

recommended beacon receiver for use with the eTrex. Other beacon receivers with the correct RTCM format may be used, but may not correctly display status or allow tuning control from the GPS unit.
The eTrex may be hard-wired to a serial connector using the Data Cable (see your Garmin dealer or visit www.garmin.com for availablity).
Refer to the wiring diagram and the eTrex unit data connection illustrated above.

Satellite Reception Tips
If the eTrex has problems receiving satellite signals, you will be prompted to answer some
questions.
A. If you are using the eTrex indoors:
Appendix G
Reception Tips
The message ‘TROUBLE TRACKING SATELLITES. ARE YOU INDOORS NOW?’ appears. Press
the UP or DOWN button to highlight ‘YES.’ Press ENTER. The message disappears.
OR:
Go outside. The eTrex will keep tracking.
B. If you are not indoors and you have not moved hundreds of miles/km
since you last used your eTrex:
1. The message ‘TROUBLE TRACKING SATELLITES. ARE YOU INDOORS NOW?’ will appear.
Press the UP or DOWN button to highlight ‘NO.’ Press ENTER.
2. eTrex then asks: ‘HAVE YOU MOVED HUNDREDS OF MILES/KM SINCE LAST USE?’. Press
the UP or DOWN button to highlight ‘NO.’ Press ENTER.
3. eTrex asks: ‘IS TODAY dd-mmm-yy?’ If you answer ‘YES’ (the date matches the current
date) the unit will continue tracking satellites and switch to the Satellite Page.
4. If you answer NO (the date is incorrect), the eTrex will do an ‘AUTOLOCATE’ and switch to
the Satellite Page.
C. If you are not indoors and you have moved hundreds of miles/km since
you last used your eTrex:
1. The message ‘TROUBLE TRACKING SATELLITES. ARE YOU INDOORS NOW?’ will appear.
Press the UP or DOWN button to highlight ‘NO.’ Press ENTER.
Clouds and weather do not affect the
operation of the eTrex!
‘AUTOLOCATE’ forces the eTrex to
search for any available satellite(s) to
determine its (your) location.
2. eTrex then asks: ‘HAVE YOU MOVED HUNDREDS OF MILES/KM SINCE LAST USE?’ Press
the UP or DOWN button to highlight ‘YES.’ Press ENTER.
3. eTrex performs an “AUTOLOCATE” and switches to the Satellite Page.
