Just changed battery but haven't got book with code for radio. There is couple of numbers on the cd changer unit underneath seat. On one side it has 82 00 002 656a, other side is c9rn832c10542559. I've put last 4 digits of each code but to no avail, the last number just flashes, I presume it automatically turns own if code is correct. Anyone have codes for this or do I need to pull stereo out and look for codes on the back? Haven't had time to do a proper search as im late for work already! Thanks in advance!
