2006 M35- Info/Navigation Screen displaying static

[frostfiresoul]

Whenever I start up my car, the Info Screen only displays static lines, unless I am backing up, in which it is normal. The A/C, Radio, and physical clock still work.

I first tried to replace the screen with one that I had bought off of eBay, but that did nothing. When I removed the Navigation Screen Input/Climate Control Panel, I found a part that seems to be called the "Dash Monitor Screen Control Module". I believe that replacing this might be able to fix this problem, but I want to verify if this is correct and ask how to remove it from the car.

Hmm, interesting one. I'm not sure if that module is also known as the AV module but by being able to see the cam, that might be okay unless it's a different sub system. If it's one and the same, you're probably on the right path.

I dont know enough about the AV control module to know if the mains creen video out is part of the control unit, or has its own wires. At least the majority of the unit seems ok, it is just data from one section that seems bad. Basically think of it like a home AV receiver and how you can select which input to use for the HDMI output. Right now "input 2" connected to the backup camera is good, but "input 1" from the main computer video feed is bad. Whether that feed runs on its own wires or is within the whole AV control module itself IDK.
