I'm not going to lie, even living in the same place for years I find we use NAV more often than you would think. Usually it isn't "how to get somewhere", but "which is the shortest route" or "arrival time" kind of situations.
I swapped an 8.4 screen into my Challenger and got lucky with the JY one I bought and it had NAV activated on it. Didn't care at first, but before I sold it I was really liking having it.
The last time I was with someone using gps it took us 45 minutes out of our way, I've heard that alot about gps. I don't think that it's all what it's made out to be. I didn't activate the on star in my Colorado z71 either
