I concure with Bob about checking the wiring, especially if the radio issue happens at the same time as the DVD player issue. With mine it was just the CD/DVD player. Radio worked 100% of the time. When the dealer worked on it he said it was wiring loose. It started again shortly after the dealer trip so I pulled it out and used crimp connections. It didn't help. Swapping the unit out for a Jensen did though. I will never own a Concertone unit again.

I didn't say it was your fault, I said I was going to blame you.
It may be that your sole purpose in life is simply to serve as a warning to others.
The things that come to those that wait will be the scraggly crappy junk left by those that got there first.
