Just curious about what others think of the accuracy of the nav system. I've never had one before and while I like playing with it, it tends to take me on surface roads when I think the hightway would be faster. I have set the system for fastest route and "yes" for highways. As an example I set a destination the other day that was 7 miles from my house. It took me on a two lane road with a traffic light every 2 blocks rather than the highway which ran parallel to the street. It always gets me there, just takes a different path.
