Audio in Truck
New iPhone 12 , 2014 GMC Sierra
Bluetooth to stereo works as long as I don’t charge phone.
When I charge phone the audio options disappear and only Dock shows up. On radio it shows connected to iPhone but no audio from maps or calls.
Pretty basic use case , how to use phone in vehicle and charge at same time ? How make dock work or keep dock dock from showing up so Bluetooth will work?
iPhone 12, iOS 14
