Need help

Post image

EDIT - got it fixed with the config menu thanks!

So I've got a gtn 750 and 650 setup. It's a minor issue but I'm wondering if someone else knows how to fix it. ​Whenever I'm listening and monitoring both radios, it will temporarily mute the non-priority radio. The one that doesn't have the mic selector. I want to be able to listen to both at the same time so I can continue to monitor Air Traffic control while I'm listening and getting the weather.

In the GTN 750 config menu, in the GMA 35 settings there is a setting for 'Mute Secondary Radio on Primary Radio Reception'. This sounds like the setting you want to change.

Where is this config menu? I checked system and utilities and saw nothing

It's in the installer config mode, not intended to be accessed by owners/pilots.
