[Paddl_E39]

Hey guys,

I'm currently upgrading my E39 from an original MK4 16.9 sat nay to the Entrynav2.
I want the Entrynav as I want to keep the original look of the 6.5 inch screen from the E39.

However, 2-3 small questions have arisen during the conversion to which I cannot find an answer.

Briefly about the general setup:

- Headunit (EN2) 6512 8792 157
- L7 CID Mid 9292247 02 6
- iDrive controller ( don't have the part number to hand at the merent, its in the car)
- IBUS NET adapter bmwcustomretrolit
- Self-made wiring harness

So far so good.
Yesterday I provisionally wired everything in my E39 and tried it out.

A problem has arisen here:
The Entrynav itself works, I can operate it via the steering wheel buttons and call up the voice control.
The Drive controller lights up together with the instrument lighting

However, the screen remains black.

Does anyone have any idea what the problem could be?

Is my screen not compatible with the headunit (Apix
