5  Glossary

Active route 

The currently navigated route. Whenever a destination is set, the route is active until 

you delete it or reach your destination. See also: Route.

City Center

The city center is not the geometric center of the city but an arbitrary point the 

map creators have chosen. In cities and villages, it is usually the most important 

intersection; in larger cities, it is one of the important intersections. 

Color theme 

The navigation system has different color themes for daytime and nighttime which 

can be selected as desired.

One daytime scheme and one nighttime scheme is always selected for the map and 

for the menus.

The navigation system uses them when it switches from day to night and back.

GPS accuracy 

Several factors have impact on the deviation between your real position and the one 

given by the GPS device. For example, signal delay in the ionosphere or reflecting 

objects near the GPS device have a different and varying impact on how accurately 

the GPS device can calculate your position. 

Map 

The navigation system works with digital maps which are not simply the 

computerized versions of traditional paper maps. Similarly to paper road maps, the 

2D mode of digital maps show you streets, roads, and elevation by colors.

In 3D mode, you can see the altitude differences, for example valleys and 

mountains, elevated roads, and in selected cities 3D landmarks and 3D buildings are 

also displayed. 

You can use digital maps interactively: you can zoom in and out (increase or 

decrease the scale), you can tilt them up and down, and rotate them left and right. In 

GPS-supported navigation, digital maps facilitate route planning. 

North-up map orientation

In North-up mode the map is rotated so its top always faces North. This is the 

orientation for example in Find on Map. 

Road Safety Camera 

This function is not available in some countries and regions.

Special alert points for speed, red light or bus lane cameras. Different data sources 

are available. You can configure the navigation system to warn you when you 

approach one of these cameras. 

Detecting the location of Road Safety Cameras is prohibited in certain countries. 

It is the sole responsibility of the driver to check whether this feature can be used 

during the trip. 

The software is capable of showing and warning for more than just cameras. Various 

other types of proximity alert points like school zones and railway crossings are also 

available. 

Route 

A sequence of maneuvers (for example, turns and roundabouts) to reach the 

destination. The route contains one start point and one or more destinations.

Track-up map orientation 

In Track-up mode the map is rotated so its top always points in the current driving 

direction. This is the default orientation in 3D map view mode. 

Vehicle marker

The current position is indicated by a blue arrow on the map. The direction the blue 

arrow is pointed indicates the current heading.
