So I've been following this thread closely and I'm very interested in adding Bluetooth to my 2009 335. I have navigation with no extra packages. I was under the assumption from reading that all US BMW's were wired for phone prep. After finding my mulf2 hi module in the trunk I noticed I do not have any extra wiring in the trunk that match the wire instructions provided in this thread. I do have the wiring needed for sate lie radio retrofit. I take it this means I will need to purchase the Bluetooth antenna with the Bluetooth antenna wire, to run back to the mulf, and I will also have to buy a microphone and wire it all the way back to the mulf. are the clear wires for the microphone a special type of wire? Does this even seem possible or am I missing something?
