Infotainment system
Navigation* Intr oduction Fig. 156
Schematic representation: Navigation
vie w A global satellite system determines the cur-
r
ent position of the v
ehicle and the sensors
mounted on the vehicle analyse the routes
taken. All measured values and possible traf-
fic events are compared with the available
maps to allow optimal navigation to the des-
tination.
Navigation announcements and graphic rep-
resentations will guide you to your destina-
tion.
Navigation management is carried out on the
screen.
Depending on the country, some functions of
the infotainment system will not be available on the screen when travelling above a certain
speed. It is not a malfunction, but is due to
compliance with l
egislation.
Navigation announcements
Navigation announcements are acoustic indi-
cations for driving referred to the current
route.
The type and frequency of navigation an-
nouncements depend on the driving situation,
for example, starting the guide to the destina-
tion, driving on the motorway or on a round-
about and the settings. If the exact destination cannot be reached
because, f
or example, it is in a non-digitised
area, indications relating to the address and
the distance to the destination are displayed
on the screen.
During dynamic route guidance, you will re-
ceive information about reported traffic con-
gestion on the route. An additional navigation
announcement is provided if the route is re-
calculated due to traffic congestion.
While a navigation announcement is playing,
its volume can be adjusted. The following
navigation announcements provided will be
played with the newly adjusted volume.
