PichaDis11 - so i tried to connect everything up. I coded 644 and 6Fl into the VO, but when i try to activate bluetooth it just keep thinking.

In NCS and tool32 it says cannot connect to ECU / Control Unit. Any idea what may be wrong? I directly used the PINs from the white to the Blue (seems to have power as i see the red MOST light up on the MULF).

Not sure what is messed up that wont let me communicate to the MULF? Is it incorrect MOST cable or likely a PIN in the MULF connector block?

Any additional insights appreciated.

Most likely the MOST cable setup. There's a PDF floating around with the directions to retrofit from BMW but that didn't work for me. You might have to reconfigure it yourself to include the mulf2 on the loop.
When the loop isn't closed I could hear faint cut outs in my speakers.

Good luck!
Hey I'm doing it now as we speak and slot one for the yellow wire is taken?? So what do I do now?

Does this Bluetooth solution support audio streaming? Or is it phone calls only?
