NEED HELP WITH FACTORY BACK UP CAMERA PLEASE!

[Jeff Joergensen]

I Got a 2022  Silverado 3500 Upfitted with a service body  For a company vehicle And In the truck  Came the factory backup camera Along with wiring harness I was able to find where plugs in underneath the bed But even after plugging it in nothing comes up on the display when I put it in reverse, Can anyone please tell me why it's not working or if there's a component that I'm missing It's so frustrating   Hooking up to trailers multiple times A-day, not having a backup camera

I think you might need to get a calibration from the dealer to activate it.
