Your phone has a dedicated Navigator key on the left side of the device for quick access to Maps. Access the Maps application by pressing the Navigator key.
When you use Maps for the first time, you may need to select an Internet access point for downloading maps. If you browse to an area that is not covered by the maps already downloaded to your device, a map for the area is automatically downloaded through the Internet.
To avoid data transfer costs, you can also use Maps without an Internet connection, and browse the maps that are saved in your device or memory card. If you want to stop Maps from establishing an Internet connection to avoid data cost, select Settings > Network settings > Allow network usage > No. This prevents your device from connecting to a network.
