Hi looking for some help here. Recently my radio and keyless quit working on my car. Radio has static like no signal. Keyless will work if you hold the remote directly to the sensor on the passenger side door handle. I searched and found a post about the radio amp on the rear window coming loose. I checked that with no luck. I changed out the radio amp on the window with a new one and still the same thing. Is there anything else that could be causing my problem? Thanks

 

sounds more like the radio frequence to me it needs to be dignosed by MB to let you no the exacat fault it sounds more like the amp aerail on the rear screen althught you ve checked it ,before anything check the fuses in the trunk on the left remove the little squre cover and they will be about 10 fuses check if any blown before visiting the dealer.......
