i am new to this nav stuff, so be kind. ok- i was out today practicing with the nav. one thing stumped me. i am driving and the nav wants me to turn right onto smith st., i can clearly see smitth street is closed off. what do i do at this point? do i tell the nav somehow, do i drive right by the street, i am confused!!!!!! please help, thanx.

Drive by the street and the navi will recalculate the route.

Drive by the street and the navi will recalculate the route.

This is true for the most part. It might try to get you to do a uturn though. Depending on where the final destination is, you might have to use some common sense and drive through a couple of the next commands to get it to truly reroute you.
