I recently bought a used 2003 E320 and I love it....but just the other day the sterio quit working. The previous time it was driven everything worked just fine and then the next time I drove it, the sterio would not power up.

When I push the power button, eventually the "Mercedes Benz" comes up bu then it goes blank again. The CD's will not come out and the 6 CD changer will not even open up.

Does anyone have any idea as to what the issue or problem is? Any help or insight would be appreciated.
