Hi Anyone know how big a job it is to replace a CD30 with a CD30 MP3? I've seen a few on ebay for sale without the required security code supplied, make of that what you will! If I had one with a security code is it simply a matter of plug in and enter code or would as suggested on some ebay auctions would a Vaux dealership and tech2 still be required? If I had one with no security code what would be required? How much for a new one be from a dealership? (Extremely unlikely I'd go this route though as I expect they are £ many 100's) TIA ... John
