The red wire of the rear camera cable provides a 12 Volt power to your
4.
rear camera. It is not necessary to connect the red wire to the power
supply. But if you want to use the parking assist function, it's
recommended to connect to the power source of your reverse lights,
so the screen will display the image of the rear camera automatically
when the vehicle is in reverse. If you need more installation information,
please reach out to
Note:
The optional rearview camera is mounted on the rear of the car. Pay
attention to its orientation during installation. Plug the rearview camera
connector into the corresponding port of the dashcam once the
installation is completed. Adjust the position of the lens to ensure that it
aligns horizontal with the ground. Start the engine to check the video
functionality of the device.
Plug the GPS module into the GPS port and secure the module to a
5.
position close to A-pillar of the car. The antenna receiver side (the side
without 3M adhesive) faces the outside and the side with 3M adhesive
faces down. It should be properly secured.
