Contact your cellular service provider or your cell phone manufacturer to see if your particular phone can download the GPS application or is already GPS enabled. If it isn’t, consider ordering a new phone. Many providers will let you download the service to your phone. Downloading must be enabled on your cell phone for you to use this option.
Once downloaded on your phone, you should find the GPS in one of your menus. This is often labeled “Navigation.” Under this screen, there will be choices, such as “Find an Address,” “Favorites,” “Find a Business,” “Get Going” and “Local Search.”
If you are looking for a place of business or an exact address, start with the street address or street name. It is best if you know the address, city and state. You do not always need the zip code. It will take some practice entering text into the various screens if you have not done so already. Take note of the “ABC” keys, caps and 123 for a numeric address.
Once you have entered all the information in the various screens, this service will give you speaking driving directions and a small on-screen map. You generally are only charged air time for accessing the service but not while it is running. Check with your service provider for exact terms and conditions.
Listen carefully. The system will give you speaking directions from your GPS location. If you make a wrong turn, it will revise the directions. Ensure your phone has enough memory to store your favorite addresses, including home and office addresses. You can change the options, such as whether you want the shortest route to a destination. You can also change the voice and display.
f you want to look up a restaurant or business, choose “local search” and it will bring up all the places within a 10-mile radius of your current GPS location. Get useful tips and resources on shopping, buying watches, perfumes, sun glasses and clocks
