the navigation system
The navigation system calculates your
position and guides you using data:
– vehicle speed and information from
the gyro (measuring the vehicle di-
rection);
– from the GPS receiver;
– from the digital map .
note:
when using the vehicle for the
first time, the speed information and
the gyro will be undergoing final cali-
bration . It is therefore normal that the
system does not provide a very precise
location until the vehicles has travelled
around fifty kilometres and undertaken
about forty pronounced corners .

navigation assistance
function
The system suggests a route to your
chosen destination using:
– its road map (on the SD card),
– the positioning sensors which esti-
mate your location even if the GPS
signals are lost,
– information from the traffic informa-
tion service (depending on country) .
Finally, it indicates the route to take,
step by step, using the display screen
and voice messages .
the gPs receiver
The navigation system uses GPS satel-
lites (Global Positioning System) orbit-
ing around Earth .
The GPS receiver receives signals
transmitted from several satellites . The
system can then locate the position of
the vehicle .
note:
after moving a long distance
without driving (ferry, rail freight), the
system may take several minutes to
adjust before retuning to normal opera-
tion .
the digital map
The digital map contains the road maps
and town maps that the system re-
quires . This is found on the SD card .
