These radios are full of gremlins. I think there have been posts about similar experiences on here before. I've had mine freeze when I put a CD in before. It wouldn't do anything until I turned the car off. For about a week the radio would switch back and forth between presets 8 & 9 every 30 seconds or so. Everything else on the radio worked fine. Since then I haven't had any other issues. I'm sure the dealer would say they can't do anything since they can't duplicate the problem.
