How to Compare Portable GPS Navigation

GPS units help give directions.

GPS stands for global positioning system. GPS units use satellites to track your location. This technology has been adapted for use in navigation devices. Some cars come with GPS navigation installed, but there are also portable GPS navigation devices available for purchase as well. Portable GPS navigation devices are useful because you can move them from car to car or take them when traveling without your vehicle. When comparing the devices, you should consider the size, maps and features each offers.

Instructions

1. Purchase a portable GPS unit with a smaller screen size if you intent to use the GPS outside of your car. The average GPS screen is about four inches, which may be cumbersome if you want to carry it on a biking trip or hike. In addition, a smaller screen size will usually cost less. However, if you have a hard time seeing the screen, you may need to invest in a larger unit.

2. Pay a premium for GPS units that speak not only the directions but the street name as well. For example, a lower-quality GPS unit may say "turn left ahead" while better GPS unit would say "turn left onto Central Avenue ahead." While the first may be sufficient for country roads, if you are driving in a congested city with closely spaced roads or roundabouts, hearing the name of the street you are looking for can be a big help.

3. Select a portable GPS unit from a company with extensive maps if you plan to take the unit on international trips. Almost all GPS units come with the United States programmed on it, but some companies offer the ability to purchase maps of Canada, Mexico, Europe and other destinations for an additional fee in the future.

4. Avoid any GPS united that do not mount on your windshield. According to Consumer Search, every state requires that the GPS unit mount on your windshield rather than sit on your dashboard.

5. Pay extra if you want your GPS to be able to connect to the internet or have bluetooth capabilities. Some GPS units offer monthly subscriptions that allow you to pay to have real-time traffic updates, movie times, gas prices and other information automatically updated on your GPS unit.
