I never thought I wanted a NAV system but I did want leather and heated seats so I got a loaded one. I'm still not used to using the Navagation part but found it extreemly handly on vacation. However my greatest interest is the Consumption and Energy screens which have helped me understand better what my TCH is doing and has heled me learn how to increase my FE. Can't say though that it would be worth $3000 since you can't get it without the leather.
