GARMIN differential beacon receiver (e.g. GBR 21) directly
from your eTrex Summit. You can enter the beacon
frequency and bit rate when you select ‘User’ from the

also ‘scan’ if you don’t know what the nearby station is,
but the unit could continue scanning if reception is
temporarily lost).

Heading Page
The eTrex Summit will automatically switch between
using Electronic Compass and GPS to determine your
heading.
The eTrex Summit needs to be held level for the
Electronic Compass to provide an accurate heading.
When mounting the eTrex Summit in a car or on a
bicycle, 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 exceeds 10 miles per hour. When you slow down,
you can press and hold the PAGE button to switch back
to using the Electronic Compass.
While mounted in a car or on
a bicycle the eTrex Summit
will be tilted enough for the
Electronic Compass to become
inaccurate. The eTrex Summit
will automatically switch to a
GPS heading when you exceed
10 mph. To switch back to the
compass press and hold the
PAGE
key or wait 90 seconds
after slowing below 10 mph.
