If you're in the market to purchase a car you might also be considering getting a GPS tracking system. The GPS tracking for cars is a technology system created by the U.S. military for navigational purposes. It has become extremely popular for use with the everyday lives of ordinary people. It can be placed on a vehicle, a phone or even a computer. The device sends signals to satellites that orbit the Earth. The satellites in turn send signals back to the GPS device, which is known as the receiver, and tells it where it is located.

As with all products available for sale there are varying degrees of features and designs in the construction of the GPS units. The Garmin nuvi 880 is rated the number one GPS device because it implements what is known as WAAS (wide area augmentation system) technology. This means there is less chance for error in the sending and receiving of signals. It also uses voice recognition technology which is superior to other models. The design of the unit is also small and compact enough that it can be used as a tracking unit without needing to be inside of a car.

Another very popular GPS device is the TomTom. There are models available that can also transmit FM stations or have media players built in. The unit has an easy to use interface which makes it a popular choice even though its overall performance is rated as average. The Harman Kardon Guide + Play 810 is liked for its sleek design. It is different than some other models of GPS units because it has a remote control that can be used to turn the rotary knob. This is desirable when driving because it's less demanding on your attention. The unit also has Bluetooth capabilities for playing music and video.

The Magellan GPS tracking for cars is a unit that has been around for awhile. It continuously is improved and upgraded into newer models with better performance. The Megellan is well liked for its design. It integrates very well into the construction of most vehicles so it doesn't appear awkward or out of place in the car. The prices of these GPS receivers vary anywhere from $400 to $800 depending on the type and features they offer. Many rental cars also come equipped with GPS tracking devices. The Hertz Company has their system called NeverLost which is equipped on over 40,000 of their vehicles in over 400 rental locations throughout the U.S. and Canada.

When considering a GPS tracking system for your vehicle it is best to discuss what is available with an authorized dealer or your automotive technician. Choosing to have a GPS system installed through the dealership of your vehicle could also be less expensive than purchasing a unit by itself. Having a GPS tracking system may also help reduce your car insurance payments.
