nav or no nav? i have seen, about around friday, a direct fit headunit, as replacement for OEM TCH head unit, with nav/dvd. direct factory fit, sorta funny looking. why would they even be making them if it's impossible to fit?
why don't you simply go to CarToys and ask them? it's free of charge. i am not working for them, but i let THEM install my HD/USB player. so that i did not have to hassle with all that electronic madness. didn't really even cost that much, $120, but i got warranty. betcha they will find something for you.
