generaL descriPtion

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);
– the digital map;
– the GPS receiver;
– the subscription-only Live Services .
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 .
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 .
)
(1/3
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 .
LiVe services
These include road safety alerts, HD
Traffic™, local search with TomTom
Places™ and the weather . At the end
of a three-month trial period, you can
extend your subscription online via
TomTom HOME™ (please see the
"System update" section) .
note: these services require a sub-
scription, and use an inaccessible SIM
card integrated into the navigation
system .
If these services are available in your
country, the Live Services icon will
appear on the navigation screen .
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);
– road safety information (speeding
warning, speed limit zone);
– HD Traffic™, from subscription to
Live Services .
Finally, it indicates the route to take,
step by step, using the display screen
and voice messages .
