cold fusion

The other day I was sitting in the car with the engine off and I was listening to the radio. I made a handsfree call using sync, while I was talking I started the engine, when I finished the call and the radio came back on I noticed that it sounded different, I checked the stettings and the bass and treble had reset back to zero. I set them both back up to max and repeated the same procedure 2 more times and the result was the same, the bass and treble reset themselves to zero each time I did this.

Same thing here, I have a 2010 with the moon and tune and on several occasions this has happened, mentioned it to the dealer and they said thay never heard of this.
