Bought a Panasonic 6" portable DVD (and MP3 Player) a few months back for $549. Has a 4 hours battery with available cigarette power adapter and noise cancelling headphones. You can buy one for all your passengers (well 3 of them at least?) for the price of the factory version. Also, the 6" model is a lot closer to the viewer than a 7" shared by all. A great alternative for those of us with cloth interiors. Too bad we are making my kid look out the window instead of watching TV. Of course, I we had the factory DVD, I would be riding in back and make the kid drive. :5:
