On my 2014 Gen 1 volt, the IPhone bluetooth has started not releasing the control of the audio. An example would be while listening to the radio, and after a turn by turn direction is given by Google Maps, the screen remains in "paused" mode forcing me to select the radio source after each direction. I talked with Apple and Chevy about the issue, Chevy said this is a known problem and they have asked Apple for a fix. I am surprised it is still not fixed and also have not seen any mention of it here. Anybody else having this problem?
