hello, got a standard concert stereo back in my s3 as it was doing my head in having an aftermarket one in there, whining away. any way. went to audi to get my code for the unit, which works. but every time i turn the car on it goes back into safe mode. the stations and bass/trebble settings are all the same as they were before. i can get hold of vagcom. so is there a way of disabling it asking for the code. oh and does anyone have a spare CD changer cartridge or know other then ebay where i can get one that will fit...... TAPES ARE RUBBISH.
