Garmin recommends having the BC 50 professionally installed.
The transmitter can be placed on metal, but it does reduce range a bit. If there’s a low signal strength, try placing it on non-metal.
It may be difficult for the transmitter to see through metal. Placing it near a vehicle's edge will help.
Placing the transmitter nearer to the navigator, the better.
Some vehicles do not provide constant minimum voltage to the reverse lamps. You should use an automotive relay when connecting the transmitter and camera to a power source that does not provide constant voltage.¹
If the BC™ 50 wireless backup camera is installed to display on the navigation device when the vehicle is put into reverse, but the image display is delayed:
Mount the transmitter closer to the navigation device.
Ensure the navigation device is attached to the compatible mount and mounting bracket.
Ensure the navigation device is attached with the correct compatible vehicle power cable.
¹ If the BC™ 50 wireless backup camera 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, leave the key turned to accessory, and put the vehicle in reverse. If the BC 50 works, 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 50 may be wired through the harness.
The BC™ 50 wireless backup camera may also be wired to a constant 12V power supply.
Move Vehicle to Another Location:
Try moving your vehicle to another location if you've only tried using the BC 50 in one location (such as your home or in a store parking lot). There may be environmental factors that can cause interference, such as signal jamming or other wireless devices.
