I have sold and installed several at my shop. Our JL Audio rep has one we put on his Land Rover. They are very expensive, but a cool option to have. If it is for kids I would just put some movies on an iPod and use that foe a video source. It is kind of like Sat radio, once you get bored listening to FM/AM, CD's, iPod's, you have the sat option. Same with track vision.
