Ok, so moving forward past which model I want to pick (although I still want input on that). The xterra dashboard is much more different than most dashes.
***Editing this whole section***
So after actually taking out the stereo last night I've come to learn that the whole dashboard in the middle is one huge piece. The air vents, AC knobs, stereo hole, emergency lights, air bag light, it's all one large piece. Photos to come later tonight. This might really complicate the project as I don't want to have to hack up my main dashboard piece to much.
Think I'll go out and buy a dremel though soon to help. Will take a lot of adjustments to get something to fit.
I'm worried that this might pose some problems when it comes to having to get my dash board to fit ANY model of the GT's. And I really want to put in the 10.1 inch.
Tonight I'm going to measure the space between the two air vents on the backside to see about the width. Once I start hacking up the dash there's no turning back.
At least removing the stock radio was a piece of cake.
