Remember how Columbus set out to find India but ended up in North America? Good job, big guy! You were a little off base on that one. Let us all learn from his navigational miscalculation and vow never to leave home without a GPS device again. Global positioning systems, or GPS, are becoming more affordable, more available and easier to use each day.
GPS Units for Automobiles
Step 1 - Affix the GPS to the dashboard or window so it is secure and not obstructing your view. If you plan to use the power adapter instead of the batteries, plug it in the car's AC outlet.
Step 2 - Turn on the GPS unit. It will automatically search for satellites to pinpoint your location. Make sure you aren't in a garage or other obstructed area or else the GPS won't be able to make a connection.
Step 3 - Enter the address of your destination. If you don't know the address, many GPS units will allow you to search nearby landmarks such as malls, museums, gas stations, etc.
Step 4 - Follow the voice prompts or observe the maps displayed on the unit until you reach your destination.
Hand-held GPS Units
Step 1 - Adjust the settings on your GPS to correspond with your maps, compass and other gear. For example, most GPS units used for hiking have an option to select either magnetic north or true north, yards or meters, etc.
Step 2 - Set waypoints to indicate landmarks on your GPS. Waypoints can be set by entering geographic coordinates, adding a waypoint from your current position, or uploading them from your PC.
Step 3 - Set alarms if you want an audio notification when you've arrived at a certain waypoint or destination.
Step 4 - Use your hand-held GPS device for activities other than bushwhacking. Use it to locate your car in a crowded parking lot, track your lost dog, or keep tabs on rascally teenagers.
