If you own a Jaguar XF, XJ, or XK and wish to add a back up camera to the OEM video screen, this product (NTV-KIT175)will allow you to do just that.
As taken from NAV-TV's website:
The GVIF-JAG Kit allows the user to add up to 3 video inputs and a backup camera input to the factory media screen in select Jaguar vehicles equipped with factory navigation. Audio integration requires that the vehicle have a factory audio input.
Note: This module is not compatible with the new Jaguar radios that have a built-in DVD player.
