control a Garmin differential beacon receiver directly from your eTrex Summit. You can enter

ally tune the receiver (you can also 'scan' if you don't know what the nearby station is, but the
unit could continue scanning if reception is temporarily lost).

The eTrex Summit automatically switches between the Electronic Compass and GPS to
determine your heading.
The eTrex Summit needs to be held level for the Electronic Compass to provide an accu-
rate heading. When mounting the eTrex Summit in a car or on a cycle, the unit will need
to be tilted in order to see the display, making the compass less accurate. eTrex Summit will
switch over, using GPS to track your heading when you exceed 10 miles per hour. When you
slow down, you can press and hold the PAGE button to switch back to using the Electronic
Compass.
