Primary pages before we start the tour, let’s briefly look at the five primary information pages used for the gps 12. Switch between pages by pressing either the q or j keys. Satellite page the satellite page shows satellite positions and signal strength. Satellite positions are displayed using two ...
Map page the map page acts as a window. It allows you to view your position, the “path” you have traveled over, and nearby waypoints. A diamond icon in the center of the screen repre- sents your current position. As you move, you will see a thin line—called a track log— appear along the path you hav...
Getting started tour now that you’ve seen the primary pages, let’s get started by taking a simple tour to show you the basics about using your gps 12. The tour assumes that your unit has been turned on and that none of the factory settings ( units of measure, selectable fields, etc.) have been chang...
Using the position page walk for 3-4 minutes and watch the position page. The direction you are moving (track), your speed, trip distance, and altitude are shown on the upper half of the screen. The latitude and longitude of your position are displayed in the middle of the page, with the time of day...
Compass page whenever you select a destination waypoint, the gps 12 provides graphic steering guidance with the compass page (the default navigation page). The “com- pass ring” in the middle of the page shows your course over ground while you’re moving, with a pointer arrow to the destination displa...
Clearing a cluttered map display after you’ve used the gps12 for a few trips, you may find that your map display has become a bit messy from keeping track of your every move. For practice, let’s clean up the screen by clearing the track log (the plot points left on the map page) we’ve just created d...
Satellite page the gps 12’s satellite page displays the status of various receiver functions. The status information will help you understand what the gps 12 is doing at any given time, and will tell you whether or not the receiver has calculated a position fix. Sky view and signal strength bars the...
Receiver status receiver status is indicated at the top left of the page, with the current horizontal accuracy (estimated position error, in feet or meters) at the top right. The status will be shown as one of the following conditions: searching— the gps 12 is looking for any avail- able satellites ...
Battery level indicator the satellite page also features a battery level indi- cator, located to the left of the sky view, which displays the strength of the unit’s batteries. The battery level indicator is calibrated for alka - line batteries. Voltage differences will display ni-cad and lithium bat...
Position page the second page in the gps 12’s primary page sequence is the position page. This page shows you where you are, what direction you’re heading, and how fast you’re going, and it’s most useful when you are trav- eling without an active destination waypoint. The graph- ic heading display a...

Tracback navigation garmin’s patented tracback feature allows you to quickly retrace your path using the track log automati- cally stored in the receiver. This feature eliminates the need to mark waypoints along the way and manually create and activate a route back to where you began your trip. Thre...
Tips on the tracback feature • always clear your track log at the exact point that you want to go back to (trail head, truck, etc.). • the ‘record’ option on the track log setup page must be set to ‘wrap’ or ‘fill’. • there must be at least two track log points stored in memory to create a tracback ...
Route navigation the last form of navigating to a destination with the gps 12 is by creating a user-defined route.

Using the compass page the compass page provides better steering guid- ance than the highway page for travel at slower speeds (e.G., walking), travel with many directional changes and when it’s not necessary to follow an exact course. The bearing (brg) and distance (dst) to the way- point are displa...
Using the highway page the gps 12’s highway page provides graphic steer- ing guidance to a destination waypoint, with a greater emphasis on the straight-line desired course and the distance and direction you are off course. The bearing and distance to a waypoint—along with your current track and spe...
Map page the map page shows your position and surround- ings, and provides you with a target cursor that lets you pan ahead to nearby waypoints, determine the dis- tance and bearing to a map position, and mark new waypoints while you navigate. The map page is broken down into two sections: control f...
Zooming, panning, and map options there are three main functions you can perform from the map page— zooming, pointing & panning, and options (changing the map/track setup and finding cities). Each of these functions has its own “field”, which may be selected and activated for use. Whenever the map p...
Zooming, panning, and map options (cont.) from the waypoint definition page, you can also define how each individual waypoint is displayed on the map.
