Trust me Rossen is the way to go.

Each kid has own headrest screen with its own DVD player, so when the older one outgrows pepperpig he can watch their own thing. Also has 15 video games. Each set has own headphones or if you want to subject yourself to mental torture you can play it over loudspeakers in car with FM link.

You can also easily link into control box any other video source you wish

Also feel it is more secure than those you just flop over headrest on strap
