While driving I notice this has happened at least 4 times intermittantly. The CD and the radio and NAVI components will stop working. The display will stay to insert CD when it is already on, I will turn off/on the radio and it works but the other day the sound turned off and my fix didn't work then all the components started just going crazy, clock turning round and round and the radio kept turning on when I turned it off. then the car won't start after sitting for one day? any suggestions...

The battery in the vehicle most likely went dead because the audio system stayed on and drained it. I recommend having the vehicle diagnosed and repaired by a Mercedes-Benz dealership because of the complexity of the audio system. The problem may be something as simple as a bad head unit or as complex as a fault in the audio gateway or fiber-optics in the vehicle. Here is a link to help you find a shop to fix you problem
