I am currently looking at upgrading my head unit to a double din dvd model. I want the best bang for my buck. Navigation is not needed. Basically, I want to listen to the radio, my mp3 player, and have a dvd play on occasion during my longer trips. I have been doing a little research and know that Kenwood and Clarion make a unit which will also allow me to port video from an IPOD...way cool! I'm also looking for a unit which will easily allow me to hack in order to play DVD's while on the move --- I know, I know so let's leave the preaching out of this please. In any case any and all information will be appreciated.
