View Full Version : Info on stock nav screen ribbon cable pinouts

Hi all,

Does anyone know where I can find the pinout info for the ribbon cable that runs from the headunit to the screen? I am working on a car pc project and would like to retain the stock information. The idea is to use a screen with multiple inputs and be able to switch between the stock information and the pc.

From what I have read elsewhere the stock display is RGB, so it shouldn't be terribly difficult to conver into something an aftermarket screen can display as long as I know what is what.

edit: for an '05 CTS V w/ bose nav.

Hmm, this looks like it refers to the plug on the back of the unit. I was expecting having to steal the signal from the ribbon cable. Can it really be this easy?
