The NAV-TV VSW is a wired video switcher with a ‘pass through’ and 2 additional video inputs for integration with factory rear view cameras. The VSW is used in Chrysler, Dodge, RAM, Ford and other vehicles that utilize the differential video standard for video or rear view camera input. The VSW, combined with the vehicle-specific NAV-TV integration module, allows the introduction of up to two different aftermarket cameras or other composite video sources into the factory LCD screen.
