I just had a wild experience. My Son called me just as I was getting to my car and I answered the phone then opened the car door and got in while talking to him. I sat down hit the power button and a few seconds later in mid sentence his voice was coming out out of the car speaker and the phone ear piece and I assume microphone was off and I was using the hands free. I had no idea this would occur in mid call. Wild. Love this car
This happens with a lot of phones. It also goes the other way. Mid conversation, switch of the car and it should transfer back to the phone.
