One of the most frequent questions we get asked is if it is possible to install a backup camera on a vehicle that already has a factory in dash video monitor. Long story short, the answer more than likely is yes.
Most cameras work of a standard RCA video connection which plenty of aftermarket in dash video monitors have, the only problem is that most factory navigation radio’s do not come equipped with a standard RCA input.
That’s where a video/navigation interface comes in. A video/navigation interface is simply a standard RCA input that can be added to many vehicles and allows the factory in dash video monitor to be used as a backup camera monitor.
There are a few companies dedicated to making these video/navigation interfaces for several makes and models among the leaders are Pac-Audio and NavTool Inc.
