Movies on Front Center Screen

[JParsonss]

I've seen a couple videos on YouTube where the front center screen, if in park, will play videos from the rear like the passenger screen does. I can't seem to figure that out and not very clear in the owners manual. Anyone have a tip on how to get this to work?

I've been trying to figure out out myself and still no luck. Hoping someone has some tips.
