Frequently asked questions

The vehicle's position on the map is
incorrect.
The Global Positioning System (GPS) indicates
the car's position with an accuracy of about
65 feet (20 meters).
Accuracy may be even less when driving on
roads lying parallel to another road, winding
roads, roads on several levels, and also after
driving a long distance without making any dis-
tinct turns.
Tall buildings and mountains, tunnels, via-
ducts, over/underpasses etc., also have a neg-
ative affect on the reception of GPS signals,
which means that the estimation of the car's
position may not be precise.
VNS does not always calculate the
fastest/shortest route.
Parameters such as distance, width of road,
06
type of road, number of right or left turns, traffic
circles etc., are all taken into account when
calculating the best theoretical route. Experi-
ence and local knowledge may, however, lead
to a better choice of route.
The VNS system chooses toll roads,
freeways, and ferries even though I have
opted to avoid them.
When calculating routes over longer distances,
for technical reasons the system can only use
major roads. If you select
76
freeways, they will be avoided as much as pos-
sible, but will be used if no other reasonable
alternative is available.
After being transported, the car's
position on the map is incorrect.
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
to calculate the car's new position correctly.
The vehicle's position on the map is
incorrect after its 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 car's
position to be calculated.
The car symbol on the map moves
erratically after a tire change
In addition to the GPS receiver, the vehicle's
speedometer and an onboard gyro are also
used to calculate the vehicle's current location
and direction of travel. If the spare tire is put on
the vehicle, or is a change is made from sum-
mer to winter tires (or vice versa), the naviga-
tion system must "learn" the new dimensions
of the tire(s). Therefore, it may be necessary to
drive for several miles, including a number of
turns, for the system to make this adjustment.
NO for toll roads and
The map image does not correspond to
actual conditions.
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 maps and data on the DVDs are static.
They will not automatically update to reflect
real-life changes to road and traffic patterns.
Updated DVDs are produced periodically.
Please contact your Volvo retailer for more
information about availability.
The map scale sometimes changes.
There is no detailed map information for certain
areas. If this is the case, the system automati-
cally changes the map scale.
Certain menu options are not available.
Check the settings that you have made. Select
Reset to default
for the particular option to
return to the default settings.
The car symbol on screen jumps forward
or spins.
The system may need a few seconds to sense
the position and movement of the car before
you drive off.
1. Switch off the VNS system and the ignition.
