When I got in the car in the morning it was working, when I cut it off and went into the store, it had stopped working. It stopped working like for an hour and a half. When I parked the vehicle and went up stairs like for 2 hours, I came back down to start the vehicle back up, and the radio started back working. The AVO came on the screen. The dealer didn't look at it, because they said as long it came back on and it didn't act up no more, they didn't have to check it. It will be hard to check the radio out.
