The BC 20 wireless backup camera provides a view of the area behind your vehicle, displayed on your compatible Garmin PND device. The system includes a camera, a transmitter, and a wireless camera PND mount. Installation involves mounting the camera, routing the cable to the transmitter, and connecting the transmitter to your vehicle's power source (preferably the reverse lamp). Testing the camera and transmitter location is crucial for optimal signal and view. Guidance lines can be adjusted for better alignment with the vehicle's path. The system allows for showing or hiding guidance lines and can be re-paired if needed.
Troubleshooting and error codes
| Issue | Possible Cause | Solution |
|---|---|---|
| No video signal | Transmitter not powered | Ensure the transmitter is properly connected to a 12-24 VDC power source (e.g., reverse lamp). |
| No video signal | Camera and transmitter not paired | Re-pair the transmitter and the PND mount by holding the PAIR button on the mount. |
| Poor video quality or short range | Interference or poor transmitter location | Ensure there are minimal obstructions between the transmitter and receiver. Test different transmitter locations. Dense metal or appliances can reduce transmission distance. |
| Camera not showing video automatically | Transmitter connected to a constant power source (not reverse lamp) | Manually select the camera icon on the PND device to view the camera feed. |
