Does anyone know if you can hard wire the Garmin Aera 760 audio out (traffic and terrain alerts) to the KMA24 audio panel? And if so what button on the KMA24 would turn on / off the audio alerts from the Garmin Aera 760.
You could wire it to the appropriate pins for ADF, DME or marker beacon on you KMA, if one of those is not currently used. I don't have the install manual at home to look up any other inputs. But since it's a radio selector not intercom, I suspect no unswitched inputs. The SPA400 manual doesn't show any inputs available, other than the audio in/out for the radio selector.
