Just wondering if anyone has figured this out. Scenario: Listening to FM/AM/SIRIUSXM Phone connected via wifi/BT/USB for CarPlay but not playing music. Sound from app plays Radio automatically switches from FM/AM/SIRIUSXM to CarPlay. I don't want this to happen but still remain conneted to CarPlay for phonecalls and easy switching when desired via Radio. Stereo in question: Pioneer AVH-W4500NEX Any help would be appreciated!
