■ 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
instructions.
To use navigation with voice guidance, you must allow the Maps application to
use a network connection.
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.
