Hey guys, new BMW owner here so pardon my lack of basic mod knowledge in some spots. I've got an E90 2009 328i produced in July. Seems like this is AFTER the cutoff for S640A, but I'm not certain. What I'm confused by is my current harness lineup. I've got the "MULF2 - High Basis SVS" and I believe Sat Radio harness that laze has, but no other harnesses in the trunk. What I'm confused by is that I don't have the bluetooth antenna nor FZD mounted microphone, which is normal, but I don't seen to have the harness plugs for them either. I can't anywhere find a tied back coax connector in the pedal trim, nor a tied back connector for a mic.
So my questions are A, are those two connectors I seem to be missing (mic and pedal trim coax) part of the S640A option which isn't installed on my car, or am I just daft and can't find them and in either case B. what do I need to complete this setup and get bluetooth functioning? Do I only need the mic and antenna? Do I need the wiring harness (and if so, where do I find the part number and installation doc? Is it a REPLACEMENT harness that would require redoing everything else as well?)? I THINK my current config is most similar to gjimmy, so insight from you would be super helpful.
Also, if I don't have S640A, why do I have the MULF2 in the trunk? What function does it serve if not the bluetooth integration? I do have USB in the center console (that seems to be useless, friggin iPhones don't work) if that has anything to do with it.
Finally, my understanding from LAZD's guide is that the free coax cable in my trunk goes to the pedal trim and can be used for bluetooth. But my understanding is that the coax in my trunk is actually part of the sat radio harness, in which case, why would it go to the pedal trim? What am I missing here?
Hopefully someone's got my similar setup and knows my pain. I have an email in to my dealer, and I'm going to try to call up BMWUSA tomorrow to get a complete options list for my VIN, since I looked under the back seat but the final configuration bill didn't include options codes.
