I recently lost sound and my screen went blank on my idrive screen. I have the CCC, i went to the dealer only for them to tell me it was the CCC and screen thats gone bad. I replaced it with the CIC unit and i still have no sound or screen. Whats going on?? someone have any idea? could it be possible that i ruined the digital cable (green and black) by possibly twisting it? I have the individual sound system
