Connect the adapter to the car. Does the unit power on with the key? If not, use a multimeter to verify your car’s red wire has +12V in ACC mode. , which provides the official pinout and wire

A critical safety wire for navigation. When +12V is applied to this pin, the microcomputer overrides the GPS dead-reckoning algorithm and instantly centers the map on the vehicle’s last known position plus forward trajectory. Failure to connect: The navigation will lag by 10-20 meters at intersections, causing "recalculating" loops. Does the unit power on with the key

Connect to the vehicle's lighting circuit to enable the unit to dim when headlights are turned on.
