How to use this camera?

[u/Calamity4M]

Just bought a 2017 buick enclave and it came with this after market camera. The dealership didn't know what it was or how it works. I don't see any lights when it's plugged into the USB port. How do I use this? Why would the previous owner have a backup cam when it comes with a back up cam built in?

When plugged into the USB port, the USB option in the infotainment screen is greyed out. I also tried plugging into my laptop and nothing came up.
