I bought my husband one when he started traveling to a lot of different locations.  Didn't realize that it acts as a blue tooth speaker phone for our cell phones.  Loved it so much that I asked for one for my birthday.  Even though I don't go to a lot of different locations, it's so easy to use and so comforting to know that I can get directions easily if I get lost (or can use it for new locations while driving).  Directions are generally quite accurate.
