The AV1 hookup in the rear, all I really want to hook up to it is my XM Inno, so I'll run a 3.5mm to RCA's. Will I be able to listen to the Inno on source AV1 and navigate at the same time? Being that I'm not using the video portion of the AV1 hookup...

Yes, just hit the map button. Inno sound will continue to come through AV1

Thank you!
