The Toyota Venza comes with a sun roof above the front seats and a panoramic roof above the rear seats. This is a very nice design but makes it very complex for installing an overhead LCD screen. We are one of the few (if any) that is able to install an overhead monitor safe and secure.
The front Kenwood eXcelon in dash touch screen with navigation controls the rear screen for the kids. Very handy especially if your siblings are not old enough to insert a disc and press play.
