It was hard to figure out how to pipe the DVD just to the back and not to the front, and listening to the audio of “Air Buddies” made my forehead sweat. Then we realized that headphones – which are supposed to be part of the DVD package – weren’t included in our test car. That’s good news, because hearing, but not seeing, a movie – especially the kiddie fare that’s likely to be shown over and over on the system – will drive you insane. However, the bad news is that the headphones aren’t wireless. They plug in up on the ceiling unit, creating yet another thing that gets in the way of the driver’s rear view.
