Hey guys,
I've searched and searched, and haven't been able to find an answer.
Posted in the Bt/Audio sub-forum, didn't get an answer, but got directed to post here.
This seems ridiculously simple, so I'm amazed I haven't found ANY info on it.
I have a '10 with 6FL option(iPhone/USB) on a base stereo, so it has the MULF2/BT module in the trunk. However, when I retrofitted the auto-dim/HL/compass rear view, I checked for BT mic wiring, and didn't see anything.
What do I need to do to get Bluetooth in my car?
I found this kit-
https://m.ebay.com/itm/Car-Microphon...%257Ciid%253A1
But am not confident that's what I need, and also not confident it's OEM/Genuine parts.
To clarify- I am not asking about BT audio streaming; I just want the OEM BT system so my wife can legally talk to me while driving(like she could in our '07 with L7)
Thanks for your time guys,
Tyler

Also, I checked for the antenna wire, and didn't see it. Is it tucked behind the kick panel by the FRM? Or is that also missing?

ptpending is correct. Your MULF has bluetooth phone functionality however it is disabled and not wired. Coding will enable. Then wiring will need to be added for antenna (to white round connector) and mic (additional pins in big plug). The only wiring going to your MULF now are power, aux in and fiber (to transfer audio to head unit).

Post the last 7 digits of your vin or run your vin and post options so we can be 100% sure your car is not pre-wired in some odd way. My E70 had separate wiring for the MULF for usb and TCU for bluetooth.

Thank you guys so much.
I think I can get part numbers from that link above to source the parts.
Last 7 are A448966- it's about as few-optioned as they come! Lots of retrofits in my future.
Power folding mirrors are next, but that's another retrofit I am having a hard time finding solid info on. Plenty of threads on it, but some say extra conductors to the FRM are needed, some say not. Since mine is an M-Sport, I'd also like to be able to swap my shadowline mirror bases onto power folding frames, but not sure if that's possible either.
So far, I know I need the co-driver door harness, the mirrors, driver door switch panel, and coding. The only unknown is the additional wiring to the FRM, and exactly what wiring that is.

I'm looking to do pretty much the same thing and I think our cars are optioned very similarly as I also have the MULF2 but no microphone. I picked up a COMBOX though, as if I'm going to add in the microphone I'm going to do it all and get bluetooth streaming as well. Thanks, ptpending for the part number.

I already swapped in power folding and auto dim mirrors to my car, I didn't need any additional wiring other than the switch and the mirrors themselves, however, I ended up getting pre-LCI mirrors. I coded them and all worked well.

I also did the auto dim rear view mirror but that was plug and play with a little bit of wiring since I didn't have the harness.

PM me if you have any questions, I'll be following along.
