Sorry man but that is crap and nothing but your isolated opinion. Just replace the "you" with "I" then you will look less foolish. If any of the below apply to you you can get quite some use and less stress from Nav.
1. You like to try new places (entertainment, restos, etc.)
2. You live in a big city
3. You use your car for business travel
4. You would rather plan your trip in your car rather than on your PC
5. You or your gf/wife are not so hot with directions
6. etc., etc., etc.
