Is there no display from the rear camera?

1. Confirm whether the rear camera used is the standard model for this dashcam; if not, there may be compatibility issues or even damage to the dashcam's mainboard, and you need to replace it with the standard rear lens for this model.
2. Check if the rear camera interface is properly connected (ensure that the extension cable is securely connected to both the dashcam and the rear camera).
3. Rear camera cable or extension cable malfunction (may be caused by damage during installation).

Switching method for rear camera

Different models have different operations for switching between front and rear views on the recording interface: some models require tapping the screen, others require swiping left or right, and some have a front/rear lens switch icon on the dashcam interface.
