iPhone works fine with car bluetooth for Playing Music but not working for Phone Calls After upgrading to iOS 13.5, I am facing issue while connecting Bluetooth of my car. I am able to connect Bluetooth of car for music and phone calls but after 2-3 minutes Bluetooth for phone gets disconnected and only music is working. Please note I am able to play music continuously.
Please note this was working fine since last 1.5 years before upgrading iOS 13.5, I have upgraded to iOS 13.6 but I am still facing issue.
Also note that I haven’t upgraded car music since the beginning, so I suspect that the issue introduced by iOS upgrade.
Buried in the last couple of updates has been a little bug that does this. I think it is tied in with the odd MAC address changing Apple devices can do for security and hiding you from tracking.
The only fix I have found is to delete the pairing on both sides (phone and in-car) and then recreate it. You may get away with just deleying the connection on the Apple but I started in the car system first :-(
Solved exactly the same issue in my Renault after about a month of the phone randomly needing reconnecting even outside a call.
