There are many types of GPS receivers.  Some of the most popular units are used for overland travel (hiking, golf, etc.), water-based travel and road travel to name a few.  This article focuses on road-based GPS navigation systems. 

Most road based GPS systems on the market today combine a number of technologies to create a highly effective navigational system.  Road based GPS navigation systems help direct you to your destination. Some of the key features that a GPS navigation system should have:

1.  Turn-by-turn navigation to your destination.

2.  Pre-loaded maps with a means to update maps over time.

3.  When turns are missed, the system should have the ability to reroute dynamically to get you back on course.

4.  Ability to save destinations for use later. For example, the system should be able to save your hotel address so you can explore big cities without the fear of getting lost on the way back to the hotel.

5.  Ability to integrate real-time FM radio traffic advisories into the route information.  The ability to receive specially formatted FM radio or Satellites service traffic information is one of the most exciting new features available.  Certain GPS receiver units are able to integrate information about traffic congestion or accidents.  Systems capable of accepting this information can then suggest an alternate route around the problem.
