Uses of GPS Mobile Navigation 

Cell phone manufacturers are installing a GPS receiver in all cell phones. The benefit of this not only means that a cell phone can be quickly located, but that cell phones will have the ability to receive driving directions, and to be used as a hand-held GPS out of the car. 

There are two ways that a GPS cell phone can be used to get driving directions. The first is to subscribe to a GPS navigation service, which is becoming available but is limited at this time. Being able to subscribe to a navigation service has its disadvantages, if you are outside your coverage area your navigation functions won’t work. Plus, not only do you have to purchase a GPS cell phone, you must also pay a set up fee and a monthly fee and be under a 3 month to one year contract.
