Sitting parked in my 05 Cayenne with the ignition on and engine not running when i got a message, battery overload. Since then a message appears on the PCM:- System Error: Amplifier, Phone, CD Changer, sat nav not available. the radio and CD still seem to play without any sound. I have tried 1+4+8 together without success, i have also taken the fuses out and reinstated without success, any information or ideas would be greatly appreciated before i have to go to the dealer.

Thank you
