Cam across a junk yard localy with a 02 factory nav unit in it. I have a 02 with the Bose, no nav. How much trouble would it be to hook this up, and do I need just the nav unit from teh dash, or is there some kind of disc player in the trunk like some cars?

 

not worth the trouble..just go aftermarket. PLUS it's CD Based so you have t switch discs all the time.
