NTV-KIT077 Overview The MB25 Kit programs the MB25 radio in select Mercedes vehicles for TV tuner emulation, allowing the user to add video and audio to the OEM system. If used for adding a reverse camera, please note that the TV button (or blank or SAT button) will have to be pressed every time the user wants to view the camera image (before shifting into reverse).

Wire Connections WARNING! DO NOT power up the NAV-TV MB25 until the end! Connecting the power to the RGB is the LAST step (for install). Follow directions carefully as this module will only attempt programming ONE time! 1. Remove the factory MB25 radio from the dashboard and set aside.

To use TV tuner emulation, press the ‘SAT’ or ‘TV’ or [blank] button once with the radio on. Video (and audio) source provided to the MB25 module and radio will display. If using this kit for a reverse camera interface, the Green wire must see 12v (+) while in reverse.
