They are 5-inch monitors. i wanted to put 7-inch but they wouldn't fit. I do have a 3-year old son that sits in the back. i put two tv's because i move his car-seat around whenever i have to fold down one of the rear seats. The main reason i had them installed is beacuse i travel to Idaho a few times a year and i live in Las Vegas. It's hard to keep a three-year old entertained in a car for eight hours. Toys can only do so much. Also, if i was into "off-roading" i would have bought a 4x4... but i'm not. If you don't like it then keep your comments to yourself.
