Volumen of COM2 on GNS430

[Chotter]

I’ve found that the volume knob on the GNS430 doesn’t work. The only way to change the volume is by using the GNS530 knob, which adjusts both COM1 and COM2. It’s very useful to have ATIS playing in the background at a much lower volume during taxi or on approach while keeping COM1 active.

Best regards
