of the screen. (This can be changed. See the topic Map Orientation, in

however, don't have to navigate to a waypoint to use the map.
Map Page is the default screen that appears when you turn on the unit.

If you're using only the factory-loaded background map, the maximum
zoom range for showing additional map detail is 20 miles. You can con-
tinue to zoom in closer, but the map will be enlarged without revealing
