I never seen this done, but i do give ya props for it, I however would have chose an LCD screen not a ntsc tv....quality reasons and an LCD screen is much more compact. Also alot of dvd decks come with fold out lcd screens so you dont have to modify so much stuff.
It looks like you put alot of work into it, looks GREAT so far, but i would find a better place for the DC other than that glove box

why dont you make a custome case or somethin for it...or a mount under the dash or somethin of the sort, that would be sweet.....
another thing...did you ever finish your third brakelight "accord"? I saw the "development" pics but not a final snapshot, thanx!
