Just wanted to share with you my new Nav works great uses built in 20gb drive, very easy to ground so you can use the nav feature while driving. I've installed it with the bluetooth module and ran the mic into the overhead console very clean cant see it. Install was pretty easy you do loose the steering wheel control not a big deal for me others prefer the Eclipse for that feature, I have an eclipse on my 350z and I think this one works much quicker. I took some install pictures if anyone needs help. I did use the metra dash kit per other's recommendations and very happy w/ the color and fitment.
