I have bought a BMW Nav 2 second hand through an auction site, but foolishly I did'nt realise that I needed a V7 disc and access code too download maps. Also after contacting Garmin they tell me I need a registration code which would have come with the unit when it was brought new. Does anyone know how or if I can get a V7 city navagation disc and code?. The unit came in box etc so I have now reason to believe that it was'nt brought from new but I can't get hold of the seller on the original site. Anyone any idea's? I would be most gratfull for any help.
