A couple things have led me to this conclusion:
1. Phone prep SA640 is not on my list
2. I do not see black or yellow cables in the bundle at all.

This leads me to believe that a mic cable has not been run from the MULF2 unit to the glove box. I do have voice control which works but perhaps that does not run to the Mulf2, is that correct?

My car is a 08/2008 build MT2009 e90 335 but it seems it is not prewired for bluetooth. I am a bit bummed if that is indeed the case.
take out your MULF2 and the big blue connector. slide out the connector from the blue casing and check if you have any wiring at pins 1 and 19. these should be the black and yellow wires. If you see these wires, your mic is already wired up.
