Has anyone installed a back-up camera that interfaces with the OEM Navi a'la FX Tech package? I'm trying to determine who the manufacturer is of the Infiniti unit, since I think this would be a plug n play install for the MO'.
Anyone know if the Nav unit sends plain old video to the LCD screen or is it directly linked (i.e. a proprietary cable, digital interface, etc.)? If it is video, could one possibly connect a switch (electronic or manual) to switch between the Nav unit and, say, a DVD player or back-up camera?
