4. Installation Guide
Follow these steps to install the PARKVISION 12V CANBUS Signal Filter:
- Identify Wiring: Locate the power wires for your reversing camera. Typically, these consist of a positive (+12V) and a negative (GND) wire.
- Connect Positive: Connect the positive input wire of the filter (labeled "12V DC INPUT" or "12 Volt+") to the positive power source for your reversing camera. This is usually the reverse light circuit or an ACC (Accessory) power source that activates when the vehicle is in reverse.
- Connect Negative: Connect the negative input wire of the filter (labeled "GND") to a reliable ground point (GND) in your vehicle.
- Connect Camera: Connect the positive output wire of the filter (labeled "12V DC OUTPUT" or "Kamera Plus+") to the positive power input of your reversing camera. Connect the negative output wire of the filter to the negative power input of your reversing camera.
- Secure Connections: Ensure all connections are secure and properly insulated to prevent short circuits.
- Test System: Test your reversing camera system to confirm that the flickering or noise issues have been resolved.

5. Troubleshooting
- Screen Flickering or Black Screen: If the issue persists after installation, double-check all wiring connections to ensure they are secure and correctly polarized (positive to positive, negative to negative). Verify that the power source provides a stable 12V.
- No Image: Ensure the camera itself is functioning correctly and receiving power. Check the video signal cable connection between the camera and the display unit.
- Intermittent Issues: Loose connections or inadequate grounding can cause intermittent problems. Re-check all connections and ensure a solid ground.
If you continue to experience problems, it is recommended to consult a professional automotive electrician.
