If you are encountering difficulty using the BC 20 Wireless Backup Camera the troubleshooting below should be able to alleviate most concerns:

Compatibility: Ensure your automotive device is compatible with the BC 20

A list of compatible devices can be found in the FAQ: Automotive GPS devices that can add a backup camera

Software Update: Update the automotive device's software using Garmin Express

The BC 20 itself does not require additional software updates; however, the compatible navigation device used with the backup camera may need to be updated from time to time.

Fuse: The BC 20 transmitter cable has a fuse assembly and requires a 500mA/250V fast-blow fuse.

Ensure that the fuse is not damaged or broken using the information here.

Installation: The BC 20 requires proper installation and the correct accessories in order to function

Confirm that the mount on the back of the automotive device is the one that came packaged with the BC 20 Wireless Backup Camera.
- The mount packaged with your compatible automotive device will not work with the wireless backup camera unless the device came packaged with the BC 20. The bracket mount that is packaged with the BC 20 includes an internal wireless receiver.
Verify that the camera is installed correctly
- Garmin recommends having the BC 20 professionally installed. Otherwise, please follow the installation instructions included with the camera.

Ensure that the transmitter is not connected directly to metal
Ensure that nothing metal is obstructing the path from the transmitter to the receiver (vehicle cable)
Use an extension cable in cases where the transmitter would be mounted further than 40-45 feet from the receiver

Pairing the Camera: The camera transmitter must be paired with the receiver connected to the device in order to display an image

Detailed instructions can be found in the FAQ: Pair the BC 20 Wireless Backup Camera transmitter and the device mount
If the device disconnects or shows a blank image after completing pairing, this can generally be resolved by rebooting the automotive device.

If the BC 20 is installed to display on the navigation device when the vehicle is put into reverse and is not displaying when the engine is running, turn off the engine but leave the ignition on and put the vehicle in reverse. If the BC 20 works, then the vehicle may require a relay.

Garmin recommends having the relay professionally installed
If the vehicle is a truck and has a seven-pin trailer wiring harness, the BC 20 may be wired through the harness
The BC 20 may also be wired to a constant 12V power supply
