Frequently asked questions

The position of the car on the map is
wrong
The GPS system shows the position of the car
with an accuracy of about 20 metres.
There is a greater chance of error when driving
on roads lying parallel to another road, on
winding roads, on roads on several levels and
after driving a long distance without making
any distinctive turns.
High mountains, buildings, tunnels, viaducts,
over/underpasses etc. also have a negative
affect on the reception of GPS signals, which
means that accuracy in calculating the position
of the car may decrease.
The system does not always calculate
the fastest/shortest route
When calculating a route, distance, width of
road, type of road, number of right or left turns,
06
roundabouts etc. are all taken into account in
order to produce the best theoretical route. A
more efficient selection of route may be possi-
ble based on experience and knowledge of the
area.
The system uses toll roads, motorways
and ferries even though I chose to avoid
them
For technical reasons, the system can only use
larger roads when calculating a route extend-
ing over a long distance.
76
If No is selected for toll roads and motorways,
then they are avoided to the greatest possible
extent and are only used if there is no other
reasonable 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 recep-
tion of GPS signals, it can take up to 5 minutes
before the position of the car is correctly cal-
culated.
The position of the car on the map is
incorrect after the car battery has been
disconnected
If power has been cut from the GPS antenna,
it can take more than 5 minutes for the GPS
signals to be received correctly and the posi-
tion of the car to be calculated.
The car symbol on screen behaves erratically
after a tyre change
In addition to the GPS receiver, the car's speed
sensor and a gyro assist in calculating the cur-
rent position and direction of travel of the car.
After fitting the spare wheel or changing from
summer to winter tyres the system needs to
"learn" the size of the new wheels.
To achieve the optimum functionality of the
system it may therefore be necessary to drive
a number of kilometres including several sig-
nificant turns.
The map image does not correspond
with the real situation
Factors such as the constant expansion and
rebuilding of the road network, new traffic reg-
ulations constantly being introduced etc. mean
that the digital map database is not always
complete. The information stored in the maps
is constantly being developed and updated.
Your Volvo Dealer can provide further informa-
tion.
See also www.volvocars.com/navi for further
information on maps etc.
The scale of the map sometimes
changes
There is no detailed map information in certain
areas. The system then automatically changes
the degree of magnification.
The expected menu option is missing
Check the settings that have been made.
Select Return to basic settings
tion in order to restore the original settings.
