first off Dibo...that is a badass path you got there amigo!
second Palmer...my head unit has everything set up like yours where everything is read in the one screen. from what i hear we are pretty much screwed unless you plan on re-doing climate control and all the other things that the screen shows. from what i hear it is possible...but not easy. only differences are that mine is bose and does not have navigation. do you have dual climate control?
