My buddy gave me his rcd 310 out of his 2012 GTI after he upgraded to a better head unit. I wanted it to replace my premium 7 in my golf, but I can't find the code anywhere on the unit and my friend doesn't have the code either. Is there anybody who can help me get the code so I can start using it. I have the serial number and the Vin from the car it came out of. :mad0259:
