You can use the mobile network to find your current
location, even indoors. This is faster but less accurate
than with GPS, and you cannot use the location as a
starting point for navigation.
To use the mobile network for positioning, select the
network-based positioning method from the device
settings. When you start the Maps application and your
GPS connection is ready, GPS replaces mobile network
as the positioning method.
