I have several vehicles and some have SiriusXM subs on the radio and others do not so I use the SiriusXM app on my OnePlus 9 Pro over bluetooth for those that don't. On my 2021 Kia Sorento factory head unit I have a SiriusXM sub but whenever I use Android Auto (wired connection) the phone's SiriusXM app starts displaying and playing on Android Auto automatically. That would be fine but I can't change channels on the head unit, only on the phone itself (that's a pain). If I select the Radio button on the head unit it changes over to the SiriusXM sub of the radio where I can change the channels. The problem is that the SiriusXM display on the Android Auto screen stays on whatever channel song was playing on the phone app when I changed it over and never changes and to change the channel I have to use the steering wheel controls, not the SiriusXM widget or screen interface of Android Auto.
I guess that this isn't a OnePlus issue but a Sirius App issue and how can I stop it from automatically launching when I connect with Andriod Auto. If anyone knows how to fix this let me know please.
