Garmin GPS III A Owner's Manual page 27

The GPS III' s Map Page combines digital charting with a number of user-selectable
features. Before we select our destination and begin navigating toward it, let' s take a
look at some of those features.
Background Roads
and Railways
The map display shows your present position using a pointer icon in the center of
the screen. The Map Page also shows any nearby lakes, rivers, highways and towns.
Use the zoom keys (IN and OUT) to adjust the map to the desired scale. The current
scale is indicated in the lower-left corner.
To change the map scale:
1. Press the IN zoom key to select a smaller scale and display a smaller geographic area.
2. Press the OUT zoom key to select a larger scale and display a larger geographic area.
The map can be oriented with the top of the page always pointing north ('North
Up'), oriented along your desired course ('Course Up'), or it can automatically rotate
to keep your current direction of travel at the top of the screen ('Track Up').
Nearby waypoints are depicted on the map with any one of over 40 different sym-
bols, with the waypoint name displayed directly above the symbol. Let' s create a way-
point directly on the map display to see how that process works, then we'll navigate
to this new waypoint.
