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 refl ecting objects near the GPS
device have a different and varying impact on how accurately the GPS device can calculate
your position.
