- A global positioning system (GPS) is a device that utilizes satellite technology to provide data for maps and positioning around the clock. Many new automobiles come with GPS systems installed. Other GPS systems can be purchased and installed or used as a portable device. Technological advancements allow new generations of GPS systems to be developed regularly. The devices are getting smaller and smaller as they also become more powerful and more accurate. As with any emerging technology, the GPS unit you purchase today will most likely be outdated by the end of the year. Consider looking for a GPS unit that can receive updates such as the Gamin 18 that plugs into a laptop with a USB port and turns the computer into a satellite receiver for GPS service.
- Decide what features are most important for your needs. Consider screen size, ease of navigation, speaking options and graphics. Typically, the larger the screen the clearer the graphics and directions. Most GPS screens range from 4 to 7 inches. Text to speech technology is particularly useful for drivers who can remain focused on the road while receiving verbal directions. Many portable units are compatible with Bluetooth technology, which allows users to pair it up with a cell phone to use the GPS in a hands-free operation mode. Find out how ready-to-go the unit is before purchasing it. Some units require a subscription for up-to-date traffic information.
- Consider your budget when you start looking for a GPS unit. The variations in price usually coincide with the number of features the unit provides, but there are less expensive models that have enough features for most users. Prices for GPS units range from under $100 for the Garmin Nuvi 200 through Home Depot to nearly $400 for the Magellan Maestro 5310 through Tiger Direct. Go to PC Magazine online for extensive price list comparisons and reviews.
- Go to GPS Magazine for extensive reviews of each model on the market. The magazine also reviews new products as they arrive on the scene by trying them out. The comments are unbiased and based on the editors' experience. While reviewers at GPS Magazine have not rated any GPS unit good enough to qualify for five stars yet, they do give four and half stars to three Gamin nuvi models that provide excellent ease of use, mounting hardware and routing capabilities. The four-star Tom Tom GO 930 has one of the best physical designs according to reviewers.
