Tapping in to the CIC unit and adding a video aux. is a fairly easy process. I'm tired of looking for a better place to mount the second phone I use for MHD and would like to just mirror it to my CIC screen. The question I have is does anyone know how I would be able to access that signal once it is connected? All the coding I have seen for the aux. video input are reverse camera engagement. Yes I know I can pay for some gadgets from vendors.
