Backup Camera Not Detected
Garmin GPS Navigation Device
Severity: ModerateWhat Does This Error Mean?
Your Garmin GPS is not receiving video from the backup camera. Garmin GPS units support wireless backup cameras that pair to the device. This error means the camera signal is not reaching the device — usually a pairing problem, power issue, or range issue.
Affected Models
- Garmin DriveSmart 65
- Garmin DriveSmart 86
- Garmin RV 890
- Garmin BC 35 (wireless camera)
- Garmin BC 40 (wireless camera)
Common Causes
- Wireless camera not paired to the Garmin GPS
- Camera not receiving power from reverse light wire
- Camera out of wireless range or obstructed
- Garmin GPS not set to display camera input
- Camera hardware fault
How to Fix It
-
Confirm the camera is receiving power — check the reverse light wire connection.
Garmin wireless backup cameras are powered from the car's reverse light circuit. If the wiring is loose, the camera has no power.
-
Pair the camera to the Garmin GPS: go to Settings > Wireless Camera > Pair Camera.
If the camera was never paired or the pairing was cleared, you need to re-pair it before it will show video.
-
Ensure the car is in reverse — most Garmin cameras only transmit video when in reverse.
Garmin wireless cameras activate when they receive power from the reverse light wire. Put the car in reverse and check.
-
Check the distance between camera and GPS — the wireless range is approximately 15 metres.
Metal body panels reduce wireless range. If the camera is mounted in the boot lid and signal is weak, repositioning can help.
-
Reset the camera pairing and re-pair from scratch.
A corrupted pairing causes detection failure. Delete the existing pairing on the Garmin and pair the camera again as if new.
When to Call a Professional
If the camera is confirmed powered, paired, and within range but still not showing video, the camera unit itself may be faulty. Contact Garmin support for a replacement under warranty.
Frequently Asked Questions
Does any backup camera work with Garmin GPS?
No — Garmin GPS units only work with Garmin wireless backup cameras (BC 35, BC 40, BC 50, etc.). Third-party wired or wireless cameras are not compatible with the Garmin screen. Check Garmin's website for compatible camera models for your GPS.
Can I see the backup camera while driving, not just in reverse?
On most Garmin models, you can manually activate the camera view while driving by tapping the camera icon. The camera switches on automatically when the car goes into reverse. Check your Garmin model manual for the exact method to access the camera view.
