How to Use GPS Effectively

GPS device

A GPS receiver uses digital radio signals broadcast by satellites to pinpoint its position. This technology was originally only available for use by the government and the military, but is now available to the general public for use as a navigation aid at a range of prices. GPS units are used for both automobile travel and wilderness exploring. Whichever GPS device you own, and whether you use it for driving or hiking, there are some simple things you can do to get the most out of your investment.

Things You'll Need

• GPS unit
• Power source
• Power cord
• Internet connection
• USB cable

Instructions

1. Charge your GPS unit fully. You can typically charge your GPS using a wall outlet, a car cigarette lighter with an adaptor, or a USB cable attached to a computer. A GPS unit is most efficient and reliable when it is fully charged.

2. Take your GPS outdoors to initialize it, i.e., to make the first satellite connection. After the initial connection, you can search for satellites from within your vehicle. Searching for satellites from inside of a building may yield poor results. Trees and high rock walls can also interfere with initializing your GPS unit.

3. Update your GPS unit regularly for the latest maps and for software bug fixes. Most GPS units can be updated online through the manufacturer's website. Refer to your user manual.

4. Protect your GPS unit from extreme heat or cold. If temperatures are extremely high or low, take your GPS indoors --- don't leave it in the car.

5. Clean your GPS regularly to keep it free of oil and dirt. Use a microfiber cloth and water or an LCD cleaner.

Tips & Warnings

• If you no longer have your user manual, it may be available on the manufacturer's website

• Do not use your GPS in overcast weather conditions. Cloudy and rainy conditions inhibit communication between the GPS and the satellites.

• Follow the manufacturer's instructions for care and maintenance of your unit. You can find them in the handbook that came with your GPS unit, or on the manufacturer's website.
