'16 Denali HD Front Camera Wiring?

[EJCarter]

Has anyone seen this before? Recently, after starting the truck, I had a message pop up on the center screen to "Service Front Camera". It also had the dismiss button at the bottom. I didn't touch anything and it slowly faded away, but it got me thinking...hmm...maybe it's pre-wired for a front camera. I've had the truck since it was new and this message has never popped up before. We can't be this lucky???

I believe there is a camera on the windshield behind the rear view mirror that is used for lane departure.  May be that camera.
