I was actually about to post a similar thread. Looks like you purchased a CD unit from MINI 2004 (July onwards, I think) or later.
Is it even possible to swap a pre-facelift radio with an after-facelift one? The former uses a round PIN connector and the latter a flat one - is there some kind of adaptor available on the market?
Do these two units even have the same size and mounting points?
Any help much appreciated
