4. Setup and Installation
This adapter is designed for straightforward installation. Please follow these steps:
- Prepare the Navigation Unit: Carefully remove your car's navigation system from its mounting location to access the rear connectors. Refer to your car's or navigation system's manual for specific removal instructions.
- Locate the Input Terminal: Identify the dedicated rear view camera input terminal on the back of your navigation unit. This adapter connects directly to this specific port.
- Connect the Adapter: Plug the green proprietary connector of the WeCar adapter into the corresponding input terminal on the navigation unit. Ensure a secure connection.
- Connect the Rear View Camera: Connect the yellow RCA male plug from your aftermarket rear view camera to the yellow RCA female plug of the WeCar adapter.

- Test the Connection: Before fully re-installing the navigation unit, test the rear view camera functionality. When the reverse gear is engaged and the reverse signal is input to the navigation unit, the screen should automatically switch to the camera view.
- Re-install Navigation Unit: Once confirmed, carefully re-install the navigation unit back into your car's dashboard.
