I have a 2007 650 convertible with a production date of 04/07 (I think). I'm thinking of getting an iPhone but read on the BMW website that it isn't compatible via USB because the production date is prior to 09/07. Does anyone know if I can have the USB connection installed by the dealer? Also, BMW site says the iPhone is not Bluetooth compatible, but I think I've seen other posts here saying that it is. Can anyone clarify?
