Thanks for the info Mike. went to the dealers today (Evan Halshaws) they were not very helpfull with the matter, ie. "Sir it's impossible as it is coded to each specific car" to which i replied "Sir you are talking out of your *rse as it is very much possible".
I would say a good car audio place would have no problems with it.

glad it helped. Are they willing to divorce the head unit. Can't be impossible as what would happen if the headunit totally failed. Make you buy a new car!!!
