Hey ALL,
I finally got everything connected for my retrofit, and coded, but cant get it to work. I have an 07 e92, no idrive, with BWW professional radio. There was no TCU or ULF in the truck, so I opted to put in a MULF2 High basis SVS. My car came with $640 already done, so I added my Antenna, MULF2 and microphone. I coded $644 and $6FL to my VO, and update the ULF_EXE to active and bluetooth to active on the 2URAD. I now have phone on my radio, but it shows 2 dashes ( --), and I cant access it. I have reset the radio, and nothing. I have tried resetting the mulf2 via NCSexpert and it doesnt find it. I tried resetting it via tool32, and it doesnt find it. I did a full module identification in INPA, and I dont see anything labeled MULF2 (or 2MULF like ncsexpert). Am I missing something? I checked fuses, as well. Any ideas?

you need add MULF2 MOST circuit to the MOST loop via switching it's ends to another part of the MOST concentrator under rear left seat trim, near door

You're right! I did that and now I can communicate with the MULF2, but still shows me Phone -- on my radio I was able to SG_RESET the unit, but nothing still. I tried pulling the $644 and $6FL from VO and adding it back, and the same with changing ULF_ECE and BLUETOOTH_RAD2 back to nicht_aktiv and then back to aktiv.

Partial Success!!! SO I ended up performing a SG_RESET on all modules and that seemed to do the trick! My phone now connects and makes calls, but the mic isnt working lol

did u do default coding?

did you connect mic to MULF? Also do you have ICOM so you can code MULF?

[ptpending]

you do not need icom to code MULF on e90, this is requirement for old e60

my second mulf is on its way to death again

these mulfs makes me angry

Yeah. There were a few mic wires in the glove box that needed to be moved around. I finally got it all connects and working

thank you! if it weren't for you I would have never figured out I was missing $640
