Clearing a Cluttered Map Display
After you’ve used the GPS 48 for a few trips, you may
find that your map display has become a bit messy from

Started tour.

Turning the Receiver Off
You’ve now gone through the basic operation of your
new GPS receiver and probably know a little more than
you think about how it works. We encourage you to
experiment with the GPS 48 until it becomes an extension
of your own navigation skills. If you encounter any prob-
lems using the unit or want to take advantage of the GPS
48’s more advanced features, turn to the reference section.

1. Press and hold the
B
