GPS tracking for cars can pinpoint the location as well as the velocity of a car. GPS, which is an abbreviation for "global positioning system," is a technology now available at a reasonable price to anyone who wishes to have navigational assistance while driving a car. Originally developed by the military, GPS may be used almost anywhere in the world to determine the latitude and longitude of a location or the GPS transmitter.

There are a few popular manufacturers of GPS systems for cars in the United States, including Garmin, TomTom and Magellan. Many luxury automobiles are sold with GPS built into the car itself. For those driving older cars or more affordable vehicles, handheld units can be purchased and temporarily mounted by suction cup on the windshield of the car. The units can be powered through a cord that connects to the car's electrical system, often in the place of the car lighter, or, in some cars, in a port specifically designed to accommodate electronic devices. GPS units average approximately two hundred dollars in price.

Most units share common features, such as memory capable of storing frequently visited locations, a "home" location, and recently used addresses. The units are also equipped to search for local destinations and points of interest, such as shops, monuments, arenas and other locations. The screen displays a map and the location of the car; drivers have the option to zoom in or out to view the route.

GPS devices can also calculate the shortest route to a destination, and often display the estimated arrival time at the destination based upon the velocity of the car, average miles per hour, type of road and distance to be traveled. GPS systems also feature an audio feature that allows users to select the gender and accent of the computer's "voice," which provides turn by turn instructions so that the driver can focus on the road instead of the device. This audio feature can be turned off, but most drivers leave it on so that they have advance warning of an upcoming exit, turn or other condition of which they need to be aware. Another useful feature of GPS tracking for cars is the system's ability to alter the route midstream.

In other words, if a driver misses a turn or an exit, or encounters a detour, obstruction, traffic jam or unexpectedly closed road, the GPS can recalculate the route based on the car's new location. GPS units can be connected to a home computer to allow owners to download current information from the manufacturer, so that the GPS computer can take into account new roads, detours, road closings, changes in names of routes or destinations, and other information that could otherwise throw the computer or the driver for a loop if not updated. GPS for cars is easy to use and convenient.

However, drivers should take care not to become too reliant on GPS, and should remain alert at all times. Maps or directions printed from an internet navigation site are advisable for long trips or destinations with which the driver is completely unfamiliar, just in case the GPS malfunctions or does not have information about a detour or road closing. Gps Tracking For Cars is a great way to get to your destination, on time.
