Retain factory backup camera with an aftermarket unit

Hi! I am having trouble retaining my factory backup camera. I managed to get the power to the camera but I do not have a video feed. I would like to know the color of the wires for video +/- where I can attach the RCA for my CX9 GT 2007 bose w/ nav.

Thank you!

I'm interested in this as well. My 2012 CX9 has the backup camera fed to the rear view mirror. I'd like to buy a modern touch screen head unit, so that the backup camera will show on it. I basically never could see the little screen on the mirror.

This might help.
