Question Mic not working with bluetooth ('04 Z4 3.0i)

Hi all - I've been a member for a couple of years and do a lot of research here for any problems that come up with my car... which I still love after 2 years of ownership.

My problem (and I have searched here, google, bimmerforums, etc.) I can connect to bluetooth, I can make a call and hear the other person, but they cannot hear me. This has not worked since I bought my car used. BMW assist works both directions (I speak and they respond,) of course I know this isn't using bluetooth, but does it use the same equipment? If I knew it was using the same MIC then I would know the problem is with the multiple phones I've paired with bluetooth... (iPhone, several Androids - have not tried a blackberry.) Or is BMW Assist totally separate?

Since I bought the car used, it's possible the previous owner had a 3rd party bluetooth device and maybe disconnected the OEM MIC?? I see an orange wire slightly coming out of the emergency brake area which makes me think there could have been an additional piece of equipment there.

Sooo... first main question, does BMW Assist use the same MIC and/or speakers that the bluetooth would use? Secondly, would anyone have a wiring diagram for the MIC? I don't have a problem taking things apart to figure this out.

Thank you for any insight on this problem. I would not create a new thread if I had not tried to find the answer already.
