If you already have a headliner installed DVD player and you want to install headrest DVDs as well, I would think you couldn't do that centrally and would have to simply plug them in, and use wired headphones. If you don't have the factory unit, then I would think it's still more trouble than it's worth to run wires for the headrests, rather than just plug things in. I see nothing in the display that indicates there are any other input options, except the USB in the console. JMHO.
