Really appreciate if somone can help me. Got a C220 coupe not long ago, all working fine. ~However... few days ago, weird things going on with my radio/CD (CD changer in glove compartment). What it is, is that i was listening to radio, and suddently just switch itself off (but the screen still on, but no sound), when i press the 'CD' button (to change to listen to cd) it says No CD (but clearly got CD in it). I can still change radio channel from one to another (ie, the button still responding and the screen still on), but, no sound. The only way i can get the sound back, is to switch the main off and then on again, but sometimes after 15mins or so, the same thing happen. It happens radomly (motorway, townroad etc etc). In the beginning, i throught it could be overheat, but last night, after i turn the engine on, after 1 mins, it happens again. And happens continuously last night. But today, on the way to work, work absolutely fine.... Can someone help. is it some button that i accidently pressed before? or can someone advice me what fault could of cause this? many thanks!!!!
