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!
