Problem with E39/E38 MID radio display

[MrSzyma]

Hello guys!

So I was soldering some cables, to make the IHKA unit, instrument cluster and the MID radio display to work using my old PC PSU.

Connecting the MID radio display alone, the display didn't light up, unless I put it in test mode.

I watched some YouTube videos, and in one of them, a guy in the comment section said that for the radio to work proberly, the I/K-bus has to be connected to the I/K-bus on the cluster.

So I soldered those together, but the display still doesn't light up.

What am I doing wrong?

Here is a link to a video I made about this problem: https://www.youtube.com/watch?v=yStyXS7gAZE
