I have had the no audio issue several times. In this case, the radio has no audio but strangely navigation will still produce audio. Whenever this happens, volume knob does nothing, and on/off does nothing. Only fix for me is to stop the car, turn it off, open the door, close the door, and restart. This fixes no audio issue for me. Fortunately I haven't had anything more severe than that.
