The radio in my Mercedes keeps turning on and off. Is there a simple fix/reset?

Thanks - I am bringing it in, but was hoping for a quick solution. I definitely will check the warranty. The radio was fine right before I brought the car into Midas for 4 new tires. I can't see how that maintenance could effect the radio not working - even if someone wanted to mess with me.

Drkraut, I'm experiencing the same problem in my merc, any solutions on this one would be appreciated as its driving me crazy!!! Cheers

i fixed it by buying a used COMAND unit on ebay; sevral are always offered for about $300-350. Just make sure it's the right year. good luck! DrKraut
