NavMate software provides turn-by-turn visual and voice assistance to direct you
to your selected destination . The software quickly calculates step-by-step direc-
tions to any destination available on the included navigation map .
The NavMate software uses Global Positioning System (GPS) satellites, and a digi-
tal roadway map database to calculate and display travel directions . The system’s
GPS antenna receives signals from a constellation of 24 satellites orbiting the earth
and uses the strongest signals to determine your position to within meters .
Vehicle Position
The NavMate software’s computer considers vehicle speed and heading changes,
together with longitude and latitude information, to accurately determine vehicle
heading and position on a digital map .
Signals from GPS satellites are used to determine the vehicle location . Three
(good) or four (best) satellites must be received to accurately determine location .
The GPS reception status is indicated by the GPS symbol on the map .
Map and Information Database
The map database used by your NavMate software was created using high-resolu-
tion aerial and land based data collection .
Car navigation maps are frequently updated . While the database was judged to
be as accurate as possible at the time of its release, a map database can never be
100% accurate . Road information that is maintained in the map databases, such as
turn restrictions or road names may change over time .
