Garmin GPS III - Manual (Page 41)

The GPS III features a powerful real-time moving map that can do much more
than just plot your course and route. The Map Page also displays background detail,
including geographic names, lakes, rivers, coastlines and highways. An on-screen cur-
sor lets you pan ahead to nearby waypoints, determine the distance and bearing to any
map position, and mark new waypoints while you navigate. The GPS III also features
dedicated zoom keys for instant zooming (see p. 2). The map portion of the page dis-
plays your present position as a pointer icon, with your track and/or route displayed
as small points on the screen (an electronic bread crumb trail, if you will). Nearby way-
points are represented with names and symbols. You may select which features are
shown via the Map Page Options (see pp. 35).
The data window beside (or above when display is vertical) the map displays the
time and distance to next waypoint, plus your current speed (all defaults). A bearing
pointer lets you know if you’re heading toward your destination. (If the pointer points
straight ahead, you’re heading directly to it.) Each data field may be configured to dis-
play any one of twenty-four data options.
Zooming and Panning
There are three main functions you can perform from the Map Page: zooming,
panning, and pointing. The map has 24 map scales (from 120 feet to 500 miles, or 30
meters to 800 km) which are selected by pressing the IN and OUT zoom keys. The
current map scale is indicated in the bottom left corner of the map display.
To change the map scale:
1. Press zoom IN to see a smaller area with more detail.
2. Press zoom OUT to see a larger area with less detail.
The Map Page displays a dig-
ital map, including lakes,
rivers, highways and towns.
