Troubleshooting and error codes

Issue

Solution

The camera takes a long time to connect or does not connect

Move the navigation device to a different location on your dash or windshield.
Remove the camera from the mount, flip it upside down, and place it back into the mount.
Mount the camera at a different location on your license plate.
Try one or more of these options to reduce sources of Wi-Fi interference: Set the wireless router in your home to use a channel other than channel 11. Turn off the Wi-Fi radio on other devices in your car, such as your smartphone or mobile Wi-Fi hotspot.

The camera does not work well in cold weather

Verify you are using lithium AA batteries in the device. Alkaline and NiMH batteries lose power quickly at low temperatures, and even brand-new Alkaline or NiMH batteries may not function at all in extremely cold environments. Lithium AA batteries provide longer battery life and more consistent power, especially in cold environments.
