In my grand wagoneer you have the option of connecting the rear screens to the vehicle wifi (if you purchase it, $200/yr) or a local hotspot. I purchased the yearly package for the first year. AS far as airplay is concerned you could hook up an apple tv (hdmi) to each screen and then prob use airplay that way. That's how i did it on mu boat. Downloading the apps to the back screens I burned through the trial data ( 1 gig ) in about 1 hour, lol. Things are glitchy but nothing major. I wish I could see the rear screens from the front passenger screen but it just says that feature not available yet. I've had it 3 days and love it. I'm not expecting perfection from something this new regardless of the price. It takes time to iron out the kinks. Just my 3 cents.
