NAV (navigation system) function selection button IntroductionGeneral points
Using sensors, the data received from the satellites and traffic
information, the best route is planned and the driver is
guided to the destination.How the system works
The current vehicle position is determined by means of the GPS satellite
system (Global Positioning System). Sensors in the vehicle measure
distances that have been driven. The values are compared to the detailed
map information contained in your navigation data and are corrected as
necessary with the support of TMC traffic reports ( TMC = Traffic Message
C hannel) page 80. With all of this data, an optimal route to the destination
is determined.
The audible navigation indications, the maps that appear on the navigation
equipment's screen and the arrows on the instrument panel screen will help
you arrive at your destination in the easiest, safest way- as if you were accom-
panied by an invisible guide.
This enables you to drive to an address in an unfamiliar town, find the nearest
petrol station or be guided to a hotel, for example.
Operation
All of the unit's audio sources are fully available while you are navigating to a
destination
14). Navigation announcements are made at the preset volume
and interrupt the active audio mode. The volume of the current audio source will then be lowered so that you do not "miss" the navigation announcement

page 12, “Changing volume settings”.
Pressing the function selection button always switches straight to the
Navigation main menu. To display the vehicle position in the map view, press
the function button.
When entering an address (town, street), only those letters or symbols which
make up a logical entry will be presented. A list of possible names will be
shown. Do not forget to enter the blank space in names made up of more than
one word, such as “St. Helens”.
The route will be recalculated if you leave or disregard the route that was orig-
inally calculated. This process takes only a few seconds.
The last announcement made can be repeated during route guidance by
pressing the setting knob page 3, fig. 1 . To also display the destina-
tion press the button. During a navigation indication, you can change the
volume by turning the volume knob .
Safety information on use of the navigation systemThe navigation system determines the position of the vehicle and its
heading, plus the distance and route to a selected destination. It takes into
account the traffic rules and regulations stored on the navigation data
medium . The system guides you using audible indications. Direction
arrows are also shown on the screen.
The destination is entered when the vehicle is stationary. The route guidance
function is designed for cars and is thus unsuitable for larger commercial
vehicles.
14)Exception: when the internal CD drive is being used to navigate directly from a navi-
gation CD.

48The route is re-planned each time an indication is ignored or the vehicle
leaves the route. This process takes only a few seconds. Only after this oper-
ation will you be able to receive driving instructions again.
Depending on the country, some functions of the radio and navigation
system may not be available on the screen above a certain speed. This is not
an error, but rather compliance with the legal requirements of the country.
Errors in navigation
The navigation system cannot receive data from the GPS satellites if you are
driving for extended periods of time below leafy trees or if you enter into a
garage, underpass or tunnel. In these cases, the vehicle's sensors will be
used for orientation.
In areas that are not or only partially digitised on the data medium, the navi-
gation system will also attempt to carry out route guidance.
Note, however, that the route guidance may be partially incorrect if the
vehicle position cannot be accurately determined or ne-way streets and street
categories (motorway, country road, etc.) are not or only partially included in
the navigation data used.
WARNING
It is fundamental that you are sufficiently alert while driving. Any distrac-
tion may lead to an accident, with the risk of injury.•Never lose visual contact with the road in order to adjust or use the
radio and navigation system.•Use the radio and navigation system only when the state of the road,
the weather and traffic conditions permit.•When adjusting the volume, keep in mind that signals from outside the
vehicle, such as a police or fire brigade horn, must be audible at all times.
WARNING
Please observe the laws of road traffic legislation when following the
recommendations made by your radio and navigation system.•The navigation system indications may be different from the actual
situation, due to, for example, construction or outdated navigation data. If
this is the case, ignore these indications and follow the traffic signs.•Traffic signs and legislation always have priority over the recommenda-
tions made by the system.•Even though information regarding one-way streets, pedestrian zones,
etc. is stored on the data medium, road traffic routing is subject to constant
changes. Information on traffic lights, stop and right of way signs, parking
and stopping restrictions or speed limits is not included in the radio and
navigation system.•Always try to adapt the speed of the vehicle to weather, road and traffic
conditions. Relying excessively on the radio and navigation system could
lead you, for example, to drive too fast in fog, which could result in an
accident.
