One mroe thing I'll add in here. How about an IR repeater so the glove box won't have to be open to control? Anyone looked into this and got it working some how?

I'm sure that would work just fine, but you wouldn't be able to see what you're doing in the player's menus. Visual feedback is rather important to many of the player's operations. You could do some pretty basic things without opening the glove box, though, and open the glove box only when needed. More trouble than I'd want to go to, but to each his own.

What about a wired steering wheel remote connection? Does your car have steering wheel buttons?

As far as theft protection is concerned and making the car look "stock", did you see my stealth install?
