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. Dif ferent 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. V
arious
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.
T
rack-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.
