The GPS III features a powerful real-time moving map that can do much morethan 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 anymap position, and mark new waypoints while you navigate. The GPS III also featuresdedicated 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 displayedas 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 areshown via the Map Page Options (see pp. 35).The data window beside (or above when display is vertical) the map displays thetime and distance to next waypoint, plus your current speed (all defaults). A bearingpointer lets you know if you’re heading toward your destination. (If the pointer pointsstraight 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 PanningThere are three main functions you can perform from the Map Page: zooming,panning, and pointing.
