The vehicle's location on the map is not correct
The navigation system's accuracy is approx. 65 ft (20 meters).
Accuracy may be reduced slightly when driving on a road that is parallel with another road, winding roads, multi-level roads and long straightaways with no distinct curves.
High mountains, buildings, tunnels, viaducts, multi-level roads, etc., may also affect GPS signal reception, which may also reduce the system's capacity to calculate the vehicle's location accurately.
The system does not always calculate the fastest/shortest route
Route calculation takes factors such as distance, road width, type of road, number of right/left turns, traffic circles, etc., into account to find the theoretically best route. Familiarity with an area may enable you to find a more efficient route to your destination.
The system uses toll roads, highways or ferries even though I have chosen to avoid them
When calculating longer routes, the system may have to choose major roads for technical reasons.
The types of roads that you have chosen to avoid will not be used if there are viable alternatives.
After being transported, the vehicle's location on the map is not correct
If the vehicle has been transported (e.g., on a ferry or train) where GPS signals have been blocked, it may take up to 5 minutes before its location will be shown correctly.
The car symbol moves erratically after new tires have been installed
In addition to GPS signals, the navigation system also uses the speedometer and a gyroscopic sensor to calculate the vehicle's current location and speed. If e.g., a spare tire or snow tires have been installed, the system has to "learn" the new tire dimensions. To do so, drive for a short period on a road with unobstructed GPS reception.
The map does not correspond to actual road conditions
Due to road changes/additions/rerouting/new traffic regulations, the map database may not be up-to-date. The database is continuously being updated. Consult your Volvo retailer.
The car symbol jumps forward or spins
Before you begin to drive, the system may need several seconds to determine the vehicle's location.
Switch off the navigation system and the ignition. Restart but remain at a standstill for a minute or so before driving.

Is the most recent map version installed?
Map information is continuously being updated. To check if the currently installed version is up-to-date or if updates are available:
- Check while the vehicle is connected to the Internet. See that article "Map updates with an Internet connection".
- Check the map version in the vehicle and compare it to the map version available on Volvo Cars' support site. See the article "Map updates from a computer with a USB flash drive".
This contains information about the current map version. See also "Updating map data with MapCare" for additional information or contact your Volvo retailer.
