Garmin GPS III Plus - Manual (Page 43)

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
cursor lets you pan ahead to nearby waypoints, determine the distance and bearing
to any map position, mark new waypoints while you navigate or retrieve exit
information. The GPS III+ also features dedicated zoom keys for instant zooming (see
pg. 2). The map portion of the page displays 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 waypoints are represented with
names and symbols. You may select which features are shown via the Map Page
Options (see pg. 36).
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
display 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 digi-
tal map, including lakes, riv-
ers, highways, highway exits
and towns.
