To Jackel, I do know a few Deharts (dated one actually) but they weren't from Bountiful!
Blue, I agree.  I thought about getting the rear speakers installed because I am a music fanatic, but I just decided to leave the car the way it is.  I love it the way it is set up right now.  The only thing I intend to add is an iPod adapter.  Has anyone had experience with this guy's stuff?

Chef, it came with the car (bought used).  I'm not sure where it came from originally!  I believe it is mounted as all other screens do, the black clips on the top part?  Honestly haven't touched the damn thing so I couldnt tell you.
