From the emails and pms im getting there seems to be a bit of confusion.
These are exactly what u see in those pics from the link. Vynil headrests with 8" monitors... these will play TV, DVD or PS2/XBOX via the video in... these do not have a DVD player, TV Receiver etc built in... none do which are built into the headrests. So if yuou have a DVD player or XBOX etc then you can plug them into these monitors if not then theyre pretty much useless.
