Step 3
Other portable GPS navigation systems include other features like voice recognition, MP3 player, and trip calculator. Those features are optional in turns of the real functions of a GPS.

Step 4
A major drawback of the portable GPS navigation system is the lack of an internal compass, accelerometer or a device used to measure the car’s speed. Without this feature, it does not navigate as accurately as a build-in GPS system when there is no GPS signal. If you live in an area where there are a lot of tunnels, high rises, or uses the GPS very frequently, it is important to buy a more sophisticated portable GPS system that has a build-in accelerometer.
