What should you look for when shopping for a GPS
There are hundreds of different GPS devices now available. It is easy to get confused when shopping around for your device. Features that where once ground breaking, such as voice guided directions, are now fairly standard. There are several factors to consider when determining the right device.
- MAPS – A GPS is pretty useless if it does not have a map of where you are traveling. Devices vary in how large an area is covered. Some devices will cover a specific region, while other GPS devices cover a continent or more. Making sure the GPS has maps for where you will travel is important when shopping for a GPS device.
- SCREEN – Avoid GPS devices with inferior or hard to read screens and non-adjustable contrast/brightness. The GPS must be easily read in a variety of lighting situations.
- CHIPSET – Older chipsets have a slower relay to the satellite, and thus poor performance.
- SIZE – If the GPS is only used in the car, a larger screen size, and this a larger unit is easier to use while driving. For portable devices, used by hikers, campers, boaters, etc, weight and size are even more important. Mid size devices are sutitable for both cars and portable use.
- BATTERY LIFE – If you will use the GPS for outdoors activities instead if primarily in the car, battery life is critical. Battery life ranges from approximately 2 hours, to over 10 hours for some devices. If you will be porting your GPS, battery life is a critical consideration in determining which is right for you.
Beyond the basics, there are tons of features now bundled with GPS devices. Some devices play additional media, such as DVD’s, MP3s, or radio. Some devices include traffic tips, and complicated best route algorithims. Review carefully any GPS before making a final decision.
