Most of us have heard of GPS systems, but don't know much about different brands, such as Garmin, Navman, or TomTom GPS software. The latter offers GPS solutions for a wide number of applications from your phone or PDA or office, including navigation in your car, on motorcycles.
For the app you want to use GPS, you just need to buy a GPS receiving device and install the appropriate software. For example, if you want to use your Treo or other smartphone as a GPS system, you will buy a mobile 5 unit. This unit connects to your phone through Blue Tooth, and gives you access to maps, door-to-door navigation instructions that remain on the screen when you call, and an easy, intuitive interface.
