Volvo SENSUS NAVIGATION Manual page 55

The system may for example use toll
roads or ferries while the driver has
chosen to avoid them
For technical reasons, the system can only use
larger roads when calculating a route extending
over a long distance.
If you selected to avoid toll roads and motorways,
then they are avoided to the greatest possible
extent and are only used if there is no other rea-
sonable alternative available.
The position of the car on the map is
incorrect after transportation
If the car is transported, for example by ferry or
train, or in such a way as to impede the reception
of satellite signals, it can take up to 5 minutes
before the position of the car is correctly calcula-
ted.
The car symbol on the screen behaves
illogically after the tyres have been
changed
In addition to the satellite receiver, the car's
speed sensor and a gyroscope assist in calculat-
ing the current position and direction of travel of
the car. After fitting the spare wheel or changing
between summer and winter tyres the system
needs to "learn" the size of the new wheels.
In order that the system shall function optimally it
is therefore recommended that the car is driven
for a while on roads with good satellite reception
(good visibility).
The map image does not correspond
with the real situation
Factors such as the constant expansion and
rebuilding of the road network, new traffic regula-
tions constantly being introduced etc. mean that
the map database is not always, in every situation,
complete.
Because of this the map data is being constantly
developed and updated - check now and again to
see if there are any updates.
The car symbol on screen jumps
forwards or spins
The system may need a few seconds to sense
the position and movement of the car before driv-
ing off.
Switch off both the system and the engine. Start
again, but remain stationary for a while before
starting to drive.
The map information is not up to date
