GPS Info
About GPS
GPS (Global Positioning System) is a sys-
tem developed and operated by the United
States which determines the current loca-
tion of the user (latitude, longitude, etc) by
generally using 3 or more satellites.
This system is used with related GPS
information, various sensors, road map
data, and other related information for the
purposes of navigation.
i Information
!ŸFor continued map updates, information
collection and surveys are continuously
being conducted to check for changes
to roads and new road construction.
Nonetheless, roads, facilities, and fares
are under constant change. Consequently,
it is impossible to completely delete any
errors, including road updates, names,
facilities, and fares. Keep such matters in
mind when using GPS.
!ŸRoads with widths less than 3m are not
included within the map data. Roads
including sections with widths less than
3m may be deleted upon updating the
map data.
When GPS information cannot be
used
GPS information may not operate under
the following conditions.

!ŸWhen buildings, tunnels, or other
obstructions block satellite signals
!ŸWhen materials are placed above the
GPS antenna and block satellite signals
!ŸWhen the satellite is not transmitting
!ŸWhen a digital cellular phone (1.5GHz)
is placed near the GPS antenna
