RE: Radio stopped Working, Please HELP!!!
I have the same problem with my 2003 E320. I still have to find the fix but I did hear the Mercedes uses fiber optics on the newer models and not hard wiring. The sensors can either go bad and or shut down (off) based on high temperature. I have been told that the dealer can re-program the sensors to a higher temperature. I am in Arizona so it needs to be set higher than say California which is where my car came from.
If I get confirmation of all of this and a solution I will post it.
