Introduction To Your Savant Navmate Software; Vehicle Position; Map And Information Database - OEM SNAV-1 Operation Manual

OE RADIO 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 OE RADIO 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.
Introduction to Software
Vehicle Position
The OE RADIO 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 OE RADIO 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.
