GPS navigation systems for cars

Home » GPS navigation systems for cars

The rapid advancement in technology in the last decade has transformed a number of devices and gadgets to a point where they are almost unrecognizable from their original form. Long gone are the days of big and awkward GPS units that had lousy reception and an accuracy that basically equaled zero. The advent of more complex and sophisticated GPS units has now made it possible for almost every new car to incorporate a portable navigation system. These gadgets are useful not only in helping you avoid getting lost, but can also inform you of the proximity and location of commercial establishments whose services you might require while on the road. The possibilities are limitless with this awesome technology!

The ability of GPS units to provide you with such useful information is due to their capability of storing “Points of interest” (POI) in their memories. Also known as “waypoints”, a GPS point of interest is stored using its geographic coordinates, plus additional information such as name and telephone number of the specific location. Precise directions are then displayed in a vector road map, while the navigation unit tells you which turn to take and how far you are from the selected destination.

When talking about the current best GPS navigation units, one must definitely mention the Garmin Nuvit 3790T. This great device comes preloaded with more than 6 million points of interest such as restaurants, hotels, gas stations, and various types of stores. However, this unit is by no means the only exceptional GPS navigation device. Other high-end models include Motorola MotoNav TN765t, the TomTom XL 340 S, and the Magellan RoadMate 1470.
