iPhone 7 in 2015 BMW 235i disconnects from Bluetooth after steaming audio for 10 seconds. Once disconnected, iOS no longer sees the vehicle's BT source. The only recourse is to forget the device in Settings and repair with the vehicle. I've isolated iOS as not the key issue (iPhone SE works fine on the same 10.0.1, so did my prior phone 6S). Apple had me swap out the device at the store; the same thing is occurring on the new iP7. Anyone with the new device able to stream audio without issues?
