NavigationOverviewSafety information regarding the use of the navigation systemThe route is recalculated each time if 
you ignore driving recommendations or  
change the route. This process takes only a few seconds. Driving recommendations can only then be re-transmitted. Incomplete navigation data The navigation system cannot receive any data from GPS satellites if you drive for  longer periods under thick forest canopy or 
 when your vehicle is in a garage, under- 
pass or tunnel. In this case, the navigation system orientates itself solely with the  help of the vehicle sensors. In regions not at all or only partially digitalised and stored as such on the navigation  CD, the navigation system will try to prov 
ide guidance to the destination. Please  
note that under these circumstances the  
guidance to the destination may not be  
completely correct if, for example, one-wa 
y streets and road categories (motorway,  
country road etc.) are not at all or only  
partially included in 
the navigation data  
used.
WARNING
Please observe the legal requirements  
for road traffic when following the  
driving recommendations provided by your radio navigation system.•
The driving recommendations provided may vary from current situa-
tions, e.g. due to road works or out of 
 date navigation data. In such a case,  
always observe the traffic regulations and ignore the driving recommenda- tions.•
Traffic signs and traffice regulations al 
ways have priority over the driving  
recommendations provided by the navigation system.•
Route guidance is subject to consta 
nt changes despite the information  
about one-way streets, pedestrian zone 
s etc. stored on the navigation CD.  
Information on traffic lights, stop and right of way signs, parking and stop- 
ping restrictions as well as lane constrictions and speed restrictions is not  included in the radio navigation system.Navigation CDInserting the navigation CD – Insert the CD into the CD case  . The program stored on the naviga- 
tion CD is loaded. Do not remove the navigation CD before the loading process is finished.
After route guidance has started, the na 
vigation CD may not 
be taken out under  
certain circumstances, e.°g in order to play an Audio CD. Up to date navigation data and new navigation CD Road guidance is subject to 
 constant changes (e.g. new streets, changes of street  
names and house numbers). A navigation CD 
 is a huge data store, which unfortu- 
nately will not be up to date after a certai 
n time. This can lead to complaints during  
route guidance. It is for this reason that you must regula 
rly update the navigation data on your unit  
with a current navigation CD.GeneralYou can continue to listen to the radio  
or play CDs during the route guidance  
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  High Wycombe.

The current TMC traffic reports can be di
splayed by pressing the selector key

Traffic problems during a dynamic route guidance  The navigation system will calculate the quickest possible route during when a  dynamic route guidance option is active. If 
 it takes longer to avoid blocked roads,  
you are guided for example around the blocked roads.Block a stretch of the route and interrogate route informationManually excluding stretches of the journey – Press the button   during the current route guidance and then  
the function key  . 
– In the menu  
block route momentarily
, you can enter and confirm  
the distance taken up by the obstruction using the button  . The route is newly calculated. 
– You must press the function key   alternatively in the main  
menu of the navigation and then select  
block route momentarily
. 
Cancel entered obstruction – Press the button   and then the function key  
. 
– You must press the function key   alternatively in the main  
menu of the navigation and deactivate the function  
block route  
momentarily 
 using the button  . 
Look up the route list – Press the function key   during the current route guidance. – Select the entry  
route list
 in order to be shown the stretches of the  
route still to be driven.
Only  
one
 obstruction can be entered for the current route guidance. 
You will be guided through a blocked area if there is no logical alternative to travel- ling through it.  Route list The route list is updated during the journe 
y. It shows the roads that you have not  
yet reached. Route sections that you have  
already travelled will be deleted from the  
route list. While pressing the button   you receive further information regarding the indi- vidual route sections. Blocked stretches of the road are displayed through a “ 
!” in a  
black box.
Note
•
It takes some seconds after route guidance has started for the route list to be 
compiled so that it can be displayed. •
The type and number of alternative rout 
es offered during an obstruction is  
determined by the detailed conten 
t of the inserted navigation CD.
Route guidance without navigation CDThe navigation function is limited and also
 possible when a navigation CD had been  
removed. You can then use the internal  
drive to play audio or MP3 CDs without  
using the navigation function. For this purpos 
e data of the navigation CD is stored  
in an internal unit “corridor memory” along the route. The possibilites of the desti- nation entry and the dynamic route guidance via TMC are only restrictively possible with this stored “route corridor”. The “w 
idth” of the route corridor depends upon  
the length of the total route to be stored. The shorter the route, the wider the stored  route corridor is and the more functions  
can be called up without inserting the  
navigation CD again. You are asked to insert 
 the navigation CD in order to continue  
the route guidance during long routes or 
 unplanned deviations from the route (e.°g  
tailback leading to detours  
based on TMC annoucements).  
A CD symbol behind the entry  
NAVIGATION
 is displayed in the navigation menu.  
This means that the unit has just stored da 
ta of the navigation CD in the corridor  
memory. The navigation CD must only be 
 removed when the CD symbol is no  
longer displayed. If the navi 
gation CD has to be removed, a current calculation or  
route guidance within the navigation 
 cannot be properly continued.
