2.1. Preface and Safety Information
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 digi-
tal map.
Signals from GPS satellites are used to determine
the vehicle location. Three (good) or greater than
four (best) satellites must be received to accurate-
ly 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 soft-
ware 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 data-
base can never be 100% accurate. Road infor-
mation that is maintained in the map databases,
such as turn restrictions or road names may
change over time.
Note: All users should read this manual prior to
operating your Caliber Personal Navigation
device with NavMate software.
