bm12 interface installed on a bmw 118 i 2012, it worked ok, except the function of controlling the digital tv and dvd idrive, I tested various settings however I noticed that none of them sends the control signal by white and black wires coming out together with the rGB plug. Is there any option to connect this command, the interface is not enabled with this option and we can do to fix this. So I'm using to inform devices compatible with the requirements of the interface.

Hello,

Did you solve the problem of BM12 video interface?
I have the same problem as you.

I think wiring of black and white RGB plug the output of the open collector, but I can not see the signal output.

Please tell me the information of problem solving.

Hello!
For BMW interfaces the manufacturer can add these functions to the interface but additional fee is charged for that.
