I have a large family, with many young children. One of the things they have clamored for is a DVD player in the car (I guess they’re not satisfied with their Game Boys, Playstation Portables, iPods, etc., etc.)

While I don’t buy the types of vehicles that come with built-in DVD players, it is possible to add a DVD player to your car — to your sun visor, of all places.

This sun visor DVD player has a 7-inch widescreen display, a built-in speaker, CD/MP3 player and remote, among other goodies.

Note that this is a right-side sun visor replacement; they do make these gadgets for left-side sun visors, but I wouldn’t recommend those under any circumstances. Installation looks simple; just remove your sun visor on that side and plug in the new one.

It looks great for a passenger (but not the driver), though I wonder how well back-seat passengers will be able to see the display. In any event, it’s an alternative to portable devices.

Or, you could try an ancient method of communication in the car — talking!
