Tap "Settings" and go to "General." Make sure that "Location Services" is turned on.
Step 2

Go back to the "Home" screen and tap "Maps." Tap the scope icon on the bottom left corner of the screen. Click "OK" when the iPhone asks if Maps can use your current location. The iPhone GPS will now locate where you are.

Tap the "Directions" tab on the bottom of the screen. Enter the address of where you want to go in the "End" field. Tap "Route."

At the top of the screen, select your mode of transportation: Car, Bus, or Walking. You should see a green pushpin marking your current location on the map. The red pushpin is your destination.

Tap the "Start" button on the upper left corner of the screen. Maps will give you step-by-step instructions on where to head next. The iPhone GPS will continue to track your location as you move.
