We are finishing up a G3X touch install in a RV6 and need a little assistance with the audio alert outputs. I could not find anything on the operation of this feature, but I do see on the interconnect wiring diagram (GTR20/GDU 46X) that the audio outputs of the 46X are connected directly to the GTR 20 (Comm Radio). I would have thought the 46X audio out would be connected directly to the audio panel (GMA 240). Which way is preferred? If it is connected to the GTR 20 (Comm 1 Radio), how is the audio heard if this Comm is not selected via the audio panel? The second Comm is a KY 97A. Thanks for the help.
