I have just bought my second fabia a 2003 silverline that came with a symphony stereo, it wasnt fully fitted so though an aftermarket head unit might have been in before, I had the code so entered it and got it working fine, the problem is everytime i start the car i have to reend the code as it keeps going inot safe mode, does anyone know how i can sort this little porblem out ???

Thanks

swap the live and ignition wires round in the isoblock at the rear of the unit.
