Aside from usual car features such as speed, security and design, car manufacturers have already included portable auto GPS as a feature of their cars. With the unending benefits a GPS can do, it is understandable why anyone would want to have it. GPS is short for global positioning system. The system consists of three segments, the space segment, control segment and the user segment. All three segments are constantly communicating with over 2 dozen space satellites orbiting the earth daily.

When initiated, the satellite sends radio waves to the GPS unit and the satellite calculates how far the vehicle is by calculating how much time it takes for the system to receive the signal from the satellite. This technology can point the exact location of the car. It also guides drivers by informing him of the nearest gasoline station, repair station, hotels or restaurants. And if the car is stolen, the owner can locate the position of the car, wherever it may be.

Auto GPS can also keep a record of the car mileage, speed and distance traveled on a trip. It can also keep records of the addresses of the car’s destination, names of the streets travelled, and how long the vehicle remained at a certain location. GPS can also benefit the car owner by updating him of basic things like when the battery is low or when the car needs to have an oil change or when it needs refueling.

Best auto GPS nowadays can even alert 911 whenever the airbag is deployed. The emergency service can automatically get the exact location of the vehicle and provide assistance to the injured driver or passenger.

Not only that, the GPS also has provided a good solution for frozen keys or lost keys. The owner can communicate directly to the GPS inside the car via phone or the internet. The driver can phone the GPS and prompt it to start the engine even if he is located at a good distance. These are only a few of the benefits a GPS has. Yet there are still other advantages which are yet to be discovered. In the next few years, it is certain that more high tech features will be programmed along with the GPS.
