The vehicle's location on the map is not correct
The navigation system displays the vehicle's location with an accuracy of approximately 20 meters (65 ft).
Accuracy may be reduced slightly when driving on a road that is parallel with another road, winding roads, multi-level roads and long stretches of road with no distinct curves.
High mountains, buildings, tunnels, viaducts, interchanges, multi-level roads, etc. may also affect the satellite signal reception, which may also reduce the system's ability to accurately calculate the vehicle's location.
The system does not always calculate the fastest/shortest route
Route calculation takes into account factors such as distance, road width, type of road, traffic intensity and speed limits to find the theoretically best possible route. Familiarity with an area and experience may enable the driver to find a more efficient route.
The system uses e.g. toll roads or highways even though I have chosen to avoid them
When calculating longer routes over greater distances, the system may choose major roads for technical reasons.
If you have chosen to avoid toll roads and highways, these will be avoided whenever possible and only used when no other viable option is available.
After being transported, the vehicle's location on the map is not correct
If the vehicle is transported on e.g. a ferry or train, or if satellite signals have been blocked for some other reason, it may take up to 5 minutes before the vehicle's location can be accurately calculated.
The vehicle symbol moves erratically on the screen after changing tires
In addition to satellite signals, the vehicle's speedometer and a gyroscopic sensor are also used to calculate location, speed and direction of travel. If any of the tires are changed, e.g. a spare tire or snow tires have been installed, the system needs to "learn" the new tire dimensions.
To help ensure the system functions optimally, Volvo recommends driving for a short period on roads with good satellite reception (clear view).
The map does not represent actual road conditions
Because road changes/additions/rerouting, new traffic regulations, etc. are always being implemented, the map database may not be up to date.
The database is continuously being updated and improved. Check regularly for updates.
The vehicle symbol jumps around or spins
The system may need a few seconds to determine the vehicle's location before you start driving.
Switch off both the navigation system and the ignition. Restart but remain at a standstill for a moment before driving.
The map information is not up to date
See the next heading.
Is the most recent map version installed?
Map information is continuously being updated and improved. When updating maps via a computer and USB, the vehicle's current map version can be displayed. Check the map version in the vehicle and compare it with available map versions in the support information at www.volvocars.com.
