INTRODUCTION TO YOUR NAVMATE SOFTWARE
The NavMate software provides turn-by-turn visual and voice assistance to direct you to
your selected destination. The software quickly calculates step-by-step directions to any
destination available on the included navigation map.
The NavMate software uses Global Positioning System (GPS)
satellites, and a digital 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 of 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-resolution 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.
