Hi folks, FOr anyone considering but not sure whether to spend the money, let me put it to rest - definitely worth the money! I had just bought BMW's in car phone adaptor for my e60. It hooks up your mobile phone to the shark fin antenna and connects to your speakers via blue tooth. As most of you may know that the reception and conncetion via blue tooth straight from the phone is a bit of hit and miss. But with the adaptor its cyrstal clear. For my motorola V8, it was RM526 (or there about). Got it from Ingress.
