Audiovox D1210 DVD Player with 12.1-Inch LCD Screen
Fantastic!
This was a great purchase!  I have already been on 2-10 hour roadtrips, one by myself with my 20 month old, and one with my husband and my 20 month old.  We even got the sound to run through the speakers of the car, with an fm transmitter that I use with my ipod.--if you do this, everyone gets to listen to the movies.  But, a 20 month old will not put on headphones--so this is a great alternative.  This unit also hangs on the wall, so when we are home it goes in our son's room.  EASY installation.  It comes with 2 cordless headphones, and 2 jacks for headphones.
