Abort the approach, and execute a
non-GPS based approach.

The GMA 35 is
reporting to the GTN
that it needs service.
The audio panel may

The GTN is configured
for Garmin audio panel

of the GMA 35 will be
possible.
Remove power from the GMA 35
audio panel by pulling the circuit
breaker labeled “Audio.” The pilot
will be able to communicate with
the Com 2 radio. Contact dealer
for service.
