Maps help you get from one place to the other but they can be bulky to use. You can purchase a GPS unit to give you directions instead. Most cell phones come with this directional system installed automatically. Here is how to work a GPS system.
Find Your Coordinates
When you are ready to plot your trip, like from galveston to houston texas, you will need to turn on your system so that a satellite can find it. If you are using your phone, tap the map application you wish to use. Once it is ready to go, choose which method of travel you are planning to use. The machine will need it to determine the best route to put you on. If you get more than one option, choose the one that you are more comfortable taking. If you plan to come back this way, follow the directions that come with your unit or phone to save the address.
Enter the Information
Find the address you wish to go to. Enter that information into the GPS as accurately as you can. On many systems, streets and cities will auto-populate when the unit gets enough information from you. Be sure that you consider which option it gives you before you select it. If the GPS has issues finding the spot, double check the house number and spelling of the street to verify its accuracy. Once the address is set, hit the button for it to go. Double check that the volume is up on the speaker or it is connected to your Bluetooth so you can listen to the directions. Listen carefully to what you are told to do so that you get to your destination safely and quickly. If you do stray off the course, the GPS will redirect itself and give you a new set of coordinates to follow until you get there.
