Audiovox Mobile Video System
great for trips
We bought this model two months ago, and so far it has been on three long trips and has worked perfectly.  Our kids love it, and it has made our road trips much more enjoyable.  The only disappointment was that the screen does NOT detach as stated in the description, but the unit hangs well between the seats with the adjustable straps.  The picture and sound are good even though the screen is on the smaller side.  The screen is viewed best head-on, as it is not very clear viewed from an angle.  Very nice carrying bag included as well.  Definitely recommend!
