a GARMIN Differential
Beacon Receiver.
To select an input/output format:

2. Select the desired setting and press ENTER.
3. If the ‘GARMIN’ format is selected, highlight the

the desired setting and press ENTER. The
‘Transfer Mode’ field allows you to specify what
information to request or send to a second GPS
12 MAP. The ‘Host’ setting lets you control all

are provided to control a GARMIN differential
beacon receiver (e.g. GBR 21) directly from your
GPS 12 MAP. You can enter the beacon
frequency and bit rate on the GPS 12 MAP and
the information will be used to tune the beacon
receiver. For more information, refer to the
owner’s manual for your GARMIN differential
beacon receiver.
