My battery was run down due to a rear light left on. It was draining for approx 2 week until I went to start it up and found it totally dead.(This is not my primary car)I was able to jump start it w/out a problem. When I went to turn the radio on, nothing came on but an LED reading "CODE" w/the "C" blinking. I tried to punch in random numbers w/out any results.[:@] What do I need to do? Is there a standard code for this system?? I've checked my manuals and nothing is listed. I would appreciate any help. Thank you!

i have an 96 E320 with the same thing. Im recently having problems with my battery staying charged for more than 2 days and when i went to start the car it read "CODE". I checked inside the manual and found a little card with a six digit number on it. Check again, but if not try going to the delear and going to the parts department and giving them the VIN number of the car.

Good luck
