Vizualogic headrest TABLETS.

If you zoom in to the top right picture, you should see a thumb drive (bottom left). That's a 64 gb thumb drive with movies. I hooked my 2TB hard drive to it and it was able to play my videos.

It is an android and can do majority of android stufffffssss. Kids love it. I only need two, but you can get all seats tablet-ized; however, it is pricey. They will just need to install a quick release at the bottom of the seats which you can tuck under the covers (if you ever remove your seats).
