iPhone 12 Problems - 2009 M35

[bluedevil30]

My IPhone 6 worked great with my car. My new IPhone 12 not so great.

My new 12 doesn’t disconnect well after a call. If I make a call right after another it may not go into hands free mode and the same with an inbound call. I have to power down my phone and repair with car to get it reset.

Any fixes for this issue? I don’t use dealers for repairs so I don’t know if there has been a software upgrade.

Probably just starting to see compatibility issues between Bluetooth 1 and Bluetooth 5

I have the same issue with my iP 11. It will dial, but the volume is very very low.

(Sigh). If Apple would just quit moving the damn furniture with every new iOS....
