Alternative to CoastaleTech's Lockpick for 2016 AV system?

[super_kev]

Hi folks, so I'm looking for a solution that will allow me to airplay (or HDMI/hardwire) movies to the rear screens, and it seems as though there was a company that made a product called Lockpick, but I can't find it and their website (https://coastaletech.com/) is out for the count. What options do I have these days to add airplay functionality so I can send a movie from an iPad or iPhone to the screens while driving? Rig is a 2016 Yukon Denali with two rear screens.
