works off the top navi unit. if that has video output of ANY sort then I can do something with it. thing being everyone is too much of a tightarse to let me try
I have a E50 El grand (same system) that has TV/navi on it. there is a big thread on this thing inthe car audio area. I posted up a lot of images on it and gave instructions on how to manually open the thing.
if all you have is the screen then I would suggest ripping it out. you need a data stream to fire it up and set the correct input on it. (it has 3 inputs.) there is no other wqay to make it run.
