this gp be simply fantastic !!! a employee at a car rental place talk I into try it out during a business trip to Atlanta last year . I be very hesitant to try it . however , I instantly see the light once I start use it . I have not travel without it since . I use to be a die hard map quester for all of my direction , but now all I need be my Garmin StreetPilot c330 . this gp make travel so much more care free , easy , and of all thing spontaneous ... just like travel should be . the interface be easy to use , and it be very helpful to have all of the map already load onto the GPS . it also come with a cigarette lighter adapter for you car and a usb cable to connect to you computer . its a bit spendy , but well worth the investment .
