Gun camera binding

[Nascar]

I have the gun camera switch bound, but it doesn't toggle.

I created bindings for the 3 positions that work. They can be bound to 3 pushbuttons, or to a 3-position switch.
But frankly, they do nothing other than changing the position of the 3-way switch in the cockpit. I don't think you'll ever be able to view gun camera footage.
So it's probably a very low, if any, priority.
