That is a kickass unit. You'd need a shoehorn to get it into your dash. But it IS possible. Some members have hacked up their dash and rebuilt it with a mix of putty filler and bondo, then repainted it with texturized paint, as if it was stock. It just takes alot of effort, some screwing up, and a dremel, to do it. If you have never done any sort of auto body work, it would be a real pain to do it.
Maybe you could put that monitor in your rear view mirror's place? Ive seen that done.
Good luck
