GPS, or global positioning satellite, technology was originally developed for military applications. In the 1980s, it was released for civilian use. In those days, however, GPS systems were extremely expensive and used mostly for sensitive scientific experiments and back-country expeditions.Today, however, GPS receivers are relatively inexpensive. It is common to find them preinstalled in new vehicles and even preloaded on cell phones. Here is what you should know to choose the GPS that is right for you.
Driving Directions
One of the most important features of a car-mounted GPS receiver is its ability to provide driving directions. Like any driving directions program, there can be inaccuracies. However, keeping the system regularly updated should minimize problems.
Look for a system that offers a voice mode. This is a highly important safety feature that prevents the need to take your eyes off the road. Better systems also let you decide between the shortest route and the fastest route, as well as scanning for road information and suggesting the best route. Some systems will automatically recalculate the route if you miss a turn or embark on a shortcut.
Maps
Like driving directions, maps can be inaccurate at times. Remember to update your system regularly to ensure that the best information is always available. The maps are highly detailed, offering the numbers as well as names of roads, and providing information on speed limits, tolls and other relevant data.
Points of Interest
One of the highlights of a good GPS system is the extensive list of points of interest. Some newer systems offer as many as six million points of interest across the country. These are typically searchable by name or distance and divided into relevant categories such as Hotels, Hospitals and Restaurants. The address and phone number of each points of interest are available, along with driving directions.
Expansion
Look for a system that accepts memory cards. Updates and additional maps can take up a great deal of memory, and memory cards are an inexpensive way to address this problem. If you are traveling, new maps can be purchased on CD-ROM and uploaded to the GPS system from your home computer.
Portability
Some systems can be disconnected from the vehicle and used as pedestrian locators. This is very helpful if you intend to explore unfamiliar cities on foot or head out on a hiking trip. Look for a system that can give walking directions as well as driving directions.
Even though your new or pre-owned vehicle may not come with a GPS Unit installed, the part department at Franklin Sussex Auto Mall can help you with a system that will not only fit your vehicle … but will also fit your needs.
