Let the Fun Begin!

This completes a basic explanation of the page features of the eTrex.

Discovering GPS Navigation
Discovering how to use your eTrex is as easy as taking a quick walk around an open outdoor area. In this brief exercise, youll mark your current location (your home for example), travel a short distance away, and then have the eTrex guide you back to where you started (to get the most out of this exercise, make sure to walk for at least the time noted for each step).

Creating a Waypoint

Youll nd the MARK option on the MENU Page.
The rst step in the exercise is to mark your location as a waypoint so you can return to it later.
NOTE: The eTrex must state READY TO NAVIGATE before you mark a waypoint.

To Mark a Waypoint:

1. Press the PAGE Button and switch to the MENU Page. 2. Press the UP or DOWN Button and highlight the MARK eld. 3. Press ENTER. The MARK WAYPOINT Page appears with OK? highlighted.
The Elevation and Position Coordinates are displayed at the bottom of the MARK WAYPOINT Page and the REVIEW WAYPOINT Page.
Before we actually mark the waypoint, lets change the symbol to a house and the name 001 to something a little more meaningful such as HOME.
To change the waypoint symbol:
1. On the MARK WAYPOINT Page, press the UP or DOWN Button to highlight the small ag symbol and press ENTER. Using the UP or DOWN Button, scroll through the symbols and highlight the house symbol. Press ENTER.
To change the waypoint name:
1. On the MARK WAYPOINT Page, press the UP or DOWN Button to highlight the Waypoint Name 001. 2. Press ENTER. The EDIT WAYPOINT NAME Page appears. 3. Press ENTER. Using the UP or DOWN Button, scroll through the letter selections. Select H and press ENTER. Repeat this process and nish the word HOME. 4. Press the UP or DOWN Button to highlight the OK eld and press ENTER. The MARK WAYPOINT Page appears. 5. Press the UP or DOWN Button to highlight the OK eld and press ENTER. Your location, named HOME, is now marked and stored in memory.

Reference

You will notice on the Map Page the little grey man. The man stands still when you are not moving, he moves when you move, and a blinking ? means the eTrex has lost satellite reception (weak signals). You should relocate the eTrex or move to a place that has a clear view of the sky.

Navigation Page Options

In addition to the Navigation Page basics that were covered on page 12, the following Navigation Page options are available: Reset Max Speed: this resets the Maximum Speed achieved during a trip. Reset Trip: the trip time, trip distance (odometer) and average speed are reset to zeros. Stop Navigation: stops any active navigation.
To select a Navigation Page option:
1. Press the ENTER Button on the NAVIGATION Page. 2. The Options Menu appears. Press the UP or DOWN Button, highlight the desired option, and press ENTER. Once you press ENTER, the change is made and the Options Menu disappears.

Route and Route Page

Routes

The eTrex allows you to navigate using one of three methods: GOTO Route TracBack The GOTO method of navigation was briey discussed on page 16. The Route feature and the GOTO feature are comparable in that they both guide you to destination waypoints. However, the route feature is more powerful because it is more automatic. When you reach one waypoint, the eTrex automatically guides you to the next waypoint on the route without needing to touch any buttons. When you use the GOTO feature you have to stop and select the next waypoint before you start moving. When you plan a trip, you can select waypoints from a waypoint list and put them into the eTrexs memory. At least Two waypoints (up to a maximum of 50) are linked together to form a route. In the eTrex, a route is at least two waypoints that describe the path you are going to travel. The Route feature is very convenient because it allows the eTrex to guide you from the rst waypoint in the route, to each successive waypoint until you reach your nal destination. When you start your trip, you activate the route feature and the eTrex points the way you should travel to get from the rst waypoint to the second. You can then use the Navigation page to give you steering guidance. TracBack, is discussed on page 28.
The ROUTE feature is found on the MENU Page.
You can use existing waypoints to build the route.

Reference Routes

There are two ways to create a route:
1. Use existing waypoints that reside in the eTrex. Choose ROUTE on the MENU Page, then add a waypoint into the route from a list of available waypoints. 2. Plan a ROUTE in MapSource on a PC, and use Save To Device to download the ROUTE to the eTrex. See your Garmin dealer for more information on using MapSource (MapSource is an optional accessory, and is not included with the eTrex).
You can insert a waypoint before an existing waypoint in the list or at the end of the waypoint list.
In either case, you can navigate to a destination using ROUTE if a route has more than two waypoints. A single waypoint route is only a normal waypoint, not a route. The eTrex will not allow the FOLLOW button to be highlighted if there is only one waypoint in the route. When you select the FOLLOW button, a list with two items is displayed letting you choose where to go. The list will always show the FIRST (BEGINNING) and the LAST (END) waypoint in the route. The eTrex will guide you to the selected nal destination following each waypoint in the route (the eTrex has one route).
To create a route from the waypoints list:
1. Press the PAGE Button and switch to the MENU Page. Press the UP or DOWN Button and highlight ROUTE. Press ENTER. The ROUTE Page appears. Press ENTER. The ADD WAYPOINT TO ROUTE Page appears. 2. Press the UP or DOWN Button to select the waypoint of your choice and press ENTER. The waypoint you selected is placed in the rst eld on the ROUTE Page. Repeat this process until all of the waypoints you want are entered into the route list. Press PAGE to get back to the page of your choice.

Reference Track Logs

What is a Track Log?
The eTrex draws an electronic breadcrumb trail or track log on the Map Page as you travel. The track log starts recording as soon as the eTrex gets a location x. If you want to keep a record of a certain track log before the track memory is lled and it begins to overwrite the earliest tracks, you can save it to the Saved Tracks list. You can save a total of ten tracks in the eTrex. Saved tracks can be used for navigation later. After a track log is saved, the saved track will have a beginning (BEGIN) and ending (END) point. This simply shows the when/where of the starting and ending points of the saved track. When you are ready to return to where you started, the eTrex will take you back by following the track log that you left behind. TracBack allows you to return along a traveled path without marking any waypoints. If you want to keep a record of a certain track log or use the TracBack feature, it is recommended that you clear the track log before you start traveling. The percentage of memory used by the current track log is displayed at the top of the page. After the track log is CLEARED, it will show zero percent. When the display shows 99%, the most recent track points will start overwriting the least recent track points. Thus, in order to avoid losing any track points, you should save the track log before it reaches 99% of memory usage.
Clearing the current track log:
1. With the MENU Page displayed, press the UP and DOWN Buttons to highlight TRACKS and press ENTER. The TRACK LOG Page will appear. 2. Highlight the CLEAR Button and press ENTER.
CLEAR the track log before starting a new trip.
You need to save the track log rst before you can use the TracBack feature.
3. You will be asked DO YOU REALLY WANT TO CLEAR THE TRACK LOG?. Use the DOWN Button to highlight YES and press ENTER to clear the current track log.
To save a track for navigation later:
1. Press the PAGE Button and switch to the MENU Page. Press the UP or DOWN Button and highlight TRACKS. Press ENTER. The TRACK LOG Page appears. 2. Press the UP or DOWN Button and highlight SAVE and press ENTER. The SAVE BACK THROUGH window appears giving you a time frame for saving a track or ENTIRE LOG. Press the UP or DOWN Button and select the desired option. Press ENTER. The saved track appears graphically on a sub page. Press the UP or DOWN Button and select OK. Press ENTER. 3. The track is now saved and appears in the SAVED TRACKS list on the TRACK LOG Page.

You can save a track from a specic time or save the entire track log.

Appendices

GPS - the Global Positioning System - is a navigation revolution. Its a technology that pinpoints a users location anywhere in the world, 24 hours a day, regardless of the weather. Designed by the United States Department of Defense for use by the military, the GPS System was made available to civilians for use in aviation, marine surveying and general outdoor/recreation markets. Today, millions of people utilize the accuracy and convenience of this amazing technology to hunt, sh, hike, y, cruise and sail. GPS consists of a constellation of 24 satellites orbiting some 12,000 miles above the earth. These satellites transmit signals containing time and orbital data to calculate satellite position and almanac data. Meanwhile, receivers used on the ground, sea and air search the sky for the satellites. The GPS unit needs to acquire good signals from at least three satellites to determine a position on the surface of the earth. A fourth signal is required to get three-dimensional positioning which determines elevation or altitude.
