A wireless terminal displays its location and navigation information (map
segment) on its display. The wireless terminal accesses a Global
Positioning System (GPS) receiver of the wireless terminal to determine
its location coordinates. The wireless terminal determines a maximum data
size for navigation information to be downloaded. The wireless terminal
sends a navigation information download request to a map server via a
supporting wireless network infrastructure that includes the location
coordinates and the maximum data size. The wireless terminal receives
navigation information that has a data size no greater than the maximum
data size and displays the navigation information on the display. The
wireless terminal may display a map segment and an icon representing the
wireless terminal at a location corresponding to the location coordinates
of the wireless terminal with respect to the map segment. The wireless
terminal may download a premises map from a premises map server.
