Questions and answers
Position of the car on the map is
incorrect or jumps
The GPS system indicates 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,
winding roads, roads on several levels and
after driving a long distance without making
any distinctive turns. High mountains,
buildings, tunnels, viaducts, over/under-
passes 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 RTI system does not always
calculate the fastest/shortest road
When calculating a route, distance, width of
road, type of road, number of right or left
turns, roundabouts etc. are all taken into
account in order to produce the best
theoretical route. Experience and local
knowledge may however lead to a more
effective choice of route.
The RTI system uses toll roads,
motorways and ferries even though I
chose to avoid them
For technical reasons the system only uses
big roads at route calculation for longer
distances. When NO is selected for toll roads
and motorways they will be avoided as far as
possible and only used if no other reasonable
alternative is 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 GPS signals, it can take up to 5
minutes before the position of the car is
correctly calculated.
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 15 minutes for the GPS
signals to be received correctly and the
position of the car to be calculated.
The map image does not correspond
with the real situation
Factors such as the constant expansion and
rebuilding of the road network, new traffic
regulations constantly being introduced etc.
means 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 information.
See also www.volvocars.com/navi for further
information on maps etc.
The scale of the map sometimes
changes
The scale is affected by the speed of the car.
At speeds in excess of 140 km/h, the largest
degree of magnification is 250 metres. When
speed is reduced to 120 km/h, the system
can once again show all degrees of magnifi-
cation.
If no detailed map information is available,
the largest degree of magnification is 500
metres, regardless of speed.
The expected menu option is missing
Check the settings applied. Select Reset to
factory settings to return to the settings origi-
nally applied.
The system indicates the route I am
already travelling when I request
Calculate new route or Diversion
The system cannot find a good alternative to
the current route.
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 driving off. Switch off both the system
and the engine. Start again, but remain
stationary for a while before starting to drive.
I'm going to make a long journey but
do not want to specify a special
destination to the cities I am thinking of
travelling through. How do I most easily
create an itinerary?
Specify the destination directly on the map
using the hairline cross. The system automat-
ically guides you to the final destination even
though you are driving beside the interme-
diate destination.
