I had this happen again last week. Performed a reset with the steering wheel buttons and the audio came back. My software has been updated since the last time this occurred. I did notice that both times the loss of audio occurred I was receiving an incoming phone call. I couldn't hear the person calling and then noticed that all audio including blinkers, radio, navigation & safety features were inoperative. Wondering if anyone else has noticed if their audio stopped working after a phone call, or if it's just a random audio cut out?
