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.
