Im looking into buying a Pioneer AVH-P4900 DVD Indash. My issue it, I want to install vision TV's but would like to have it so I can play a cd through my Indash, but use a seperate DVD player to play a video at the at the same time. I know its possible with the visior TV's, but could I also use the video in on the indash to play a video through the screen and still play a cd? Doesn't matter if the Video audio plays or not. For using an external DVD player, where could I find a kit for a single din indash with an 1/2 din opening on the bottom? Also, I have an 2005 Chevy Impala, I was looking into buy a double din indash, but have had mixed reviews about the fitting issues, some say it fits right in, some say it takes some fabircation, can anyone clear this up?
