Overview
VHF Comm
The GPSMAP 495 can also output frequency data to a Garmin aviation
radio. Currently the two models supported are the SL30 nav/comm and
the SL40 comm. Refer to
for wiring information.
CAUTION:
This interface does not have an FAA installation
airworthiness approval. If any abnormalities with SL 30/40
tuning or operation are encountered, disconnect the GPSMAP
495 from the SL 30/40 tuning interface.
To configure the VHF comm output:
1. Press
MENU
twice. The Main Menu appears.
2. Highlight the
Setup
tab.
3. Use the

field and use the
ROCKER
to select
TIS In/NMEA & VHF Out

Nearest VOR frequencies (SL30 only)
NOTE:
See your
SL30/40 User’s Guide
regarding information

You can also use the GPSMAP 495 to directly tune a standby
frequency in the radio by using the Comm tab when reviewing an
airport.

NRST
key to select an airport.
2. Highlight the

sub tab.
