The Global Positioning System (GPS) is operated by the government of the United 
States, which is solely responsible for its accuracy and maintenance. The accuracy 
of location data can be affected by adjustments to GPS satellites made by the 
United States government and is subject to change with the United States 
Department of Defense civil GPS policy and the Federal Radio navigation Plan. 
Accuracy can also be affected by poor satellite geometry. Availability and quality 
of GPS signals may be affected by your location, buildings, natural obstacles, and 
weather conditions. The GPS receiver should only be used outdoors to allow 
reception of GPS signals.
Any GPS should not be used for precise location measurement, and you should 
never rely solely on location data from the GPS receiver and cellular radio 
networks for positioning or navigation. 
■ Extra services
Maps also supports navigation with voice guidance, which requires a regional 
licence. To use this service, you need a compatible external GPS device that 
supports Bluetooth wireless technology.
To purchase a navigation service with voice guidance, select Menu Maps 
Extra services Purchase navigation or Check map updates, and follow the

The navigation licence is connected to your SIM card. If you insert another SIM 
card in your phone, you are asked to purchase a licence when starting navigation. 
During the purchase procedure, you are offered to transfer the existing navigation 
licence to the new SIM card without extra charge.
