Auto navigation systems and GPS devices are everywhere you turn in this day and age. You can find them in your car, boat, plane, even in your purse (if you have a PDA or cell phone with GPS capabilities combined with the right software and/or subscriptions). If that isn’t enough for you, you also have the option and capability of turning your laptop computer into a GPS device if that is your desire. The thing that most people forget to check out or ask about when looking at all the nifty features of unit A over unit B is how easy is the unit you are considering to use?
