I borrowed a genuine BMW V28 OS disc from my local dealer and still no luck
Disc has been in the car now for 2 hours GRRRRRR

What does the ibus wire look like

I have followed the instructions exactly
The unit takes the dics and then makes a few wiring noises and then nothing.
It dosent sound like the disc is even spinning

P.S. Thanks for everones help so far!!!!!!
