DIP Switch Configuration
The TF-NTG5 module features DIP switches for specific configurations. Refer to the image below for the location of the DIP switches.

The accompanying wiring harness includes various connectors for integration with the vehicle's Comand Online system.
The default configuration for video-in-motion activation is usually pre-set. Consult the specific instructions provided with your unit or the manufacturer's website for detailed DIP switch settings if custom functionality is desired. For standard video-in-motion, typically all switches are in the 'OFF' position or as specified by the manufacturer for your specific vehicle model.
