BMW E90 Reverse Camera CAN Codes

Hello, I'm currently in the process of installing a CarPC in my E90. I want to connect it to the CID (Central Information Display). However, when I do this, I don't get a picture on the CID. I've read that the TV module or the LVDS module sends CAN signals to the bus to prevent the display from being deactivated. Does anyone know the CAN codes so I can send them to the bus with my CarPC? I really don't want to spend 200 euros on an interface!
Best regards,

Can anyone of you help me?

Can any of you help me?
Hmm, my email has been stuck in the outbox since yesterday.

What happens if you receive the following message:
4F3 8 73 01 FF FF FF FF FF FF

sends?

Bye.
Andi.
