Frequently Asked Questions
Are backup cameras required on new vehicles?
Yes. As of May 2018, all new vehicles sold in the United States are required to have a backup camera as standard equipment per federal regulation.
Why does my camera image appear foggy?
The camera lens can become cloudy from UV exposure, road grime, or moisture inside the housing. Cleaning the lens may help, but if the inside is foggy, the camera unit needs replacement.
Can wiring at the liftgate cause intermittent camera failure?
Yes. The camera wiring runs through the liftgate hinge area and flexes with every open and close cycle. This is one of the most common causes of intermittent backup camera failures.
