be of a certain age and extremely technology impaired , I be very concern over my ability to learn how to use the Garmin 320 . much to my surprise , I be able to use it right out of the box . it be very intuitive . my only problem be when I just want to enter a city and state . I learn you have to input a street address first . so now I just enter the first address that appear and update it when I arrive near my destination . love it !
