Automobile GPS navigation systems provide drivers with dynamic street and highway maps, driving directions, and directories of restaurants, hospitals, car services, and other points of interest (POI). Voice prompts and alerts let the driver keep his attention on the road.
The newest and best GPS systems have full-color 3-D street maps, traffic alerts and rerouting, integrated hands-free cell-phone use, and easy touch-screen controls. Some of the best GPS models, such as the Garmin Nuvi 1690 and 1490, have wide-screens, FM transmitters so that you can hear your voice prompts and alerts through your car stereo system, Bluetooth wireless connection to your cell phone, theft prevention features, long-life battery operation, and more.
People who use such systems for the first time are usually amazed at the devices’ incredible accuracy and almost-magic capabilities. They often wonder why they didn’t get one sooner and how they could possibly do without one in the future.
There are three ways to acquire a car GPS system.
One is to buy a new vehicle with the navigation system already installed. The second method is to buy an aftermarket in-dash unit (e.g., Pioneer) that replaces your standard radio or stereo system. And the third method is to buy a separate portable unit, such as those by Garmin and TomTom, that can be easily mounted to your vehicle’s dash or windshield.
