No one in the world would or should know someones
radio code

Should you know the codes of all your neighbors car radios?

Ask a dealers parts dept or service mgr for help in getting & installing the code

hi, your best bet is to go to a stereo sales place like best buy and get an install kit specifically for your car, that way there is no cutting wires, everything will just plug right in and they sell kits that will allow you to install aftermarket units directly into the dash without cutting anything. Very professional.

it is in the boot o/s/r below covers

There should be a fuse on the stereo itself, to remove it you will need the special radio pins to remove

OK whos broke the wire ??? stop using the back seat ¿¿¿

I have the same problem. Did you get anyone to help you? I have the same car. A4 1.8T 2005 with the Symphony factory radio.
