MaroonC63

I have a 2009 c63, and after i unplugged my ipod from the aux then replugged it all the buttons became dark and the lights wont turn on, the aux doesn't work anymore, and the screen keeps saying entertainment system will shut down if you don't turn on the engine. The buttons won't light up, and when i go to audio using the steering wheel it just has 4 dashes like this ------. anyone know how to fix this problem? tried resetting everything to factory settings but no good.

unhook your battery for a couple of minutes.
