Ok so Ive read in many threads that US e90s are prewired for bluetooth, however I don't believe mine is. I have an 09 328i and have USB in my center console, and read somewhere that all I need for that is the antenna and microphone and all the wires should be there to connect to. I looked under the mat in the trunk and saw what i believe is called an MULF and it has a bluetooth sign on it. So I bought a mic to put in the overhead console, and when I looked for a connection for it, it was nowhere to be found up there. I looked everywhere in that tiny space for the mic connector and could not find it! Is it in a hidden place or is my car not prewired?? Anyways, I decoded my vin and these options came up. Please let me know if one of these options indicate it is prewired because Im convinced its not.

Yes but my car appears to not be prewired so I'm not sure how to go about that

Read the friggen link there are discriptions on what to do. Also only bluetooth phone is possible with Pro Radio no streaming music on last check.

Yes I understand the no streaming music isn't possible. And the links and retrofit diys that are on the web are for prewired cars. Cars only have mulf instead of the other one because of they have USB input in the center console.

The first post in the link he gave you had your answer.

The PDF file entitled "no preparation" applies to your car.

Im not sure if this works for mulf (as opposed to internal hu) base bt, but i was able to buy a mic and a retrofit bt cable (actual bmw part no for this) that was the perfect length to go down the a pillar to the back of the hu. It then connects into the vehicle harness. Not sure if in your case it would pass the audio stream back to the mulf. I think it might.
