Route & Sound - Navigating and listening to an
audio CD
With the new generation of our navigation radio units, you may insert
a map CD, plan your route, then insert an audio CD and the system will
still guide you to your intended destination. The navigation computer
saves the road system in a defined area around the planned route
(corridor) in its main memory. Within this corridor, the map CD does not have to be
inserted in order for the navigation to function. As soon as you leave this corridor, a
message will appear automatically, prompting you to insert the map CD so that the
navigation computer can reload the data required for a new route.

Expanded Route & Sound function
What is meant here is destination input without a map CD. If the new destination is
within the range of the map section (corridor) stored in the main memory, it is
possible to enter a new destination without the map CD.
What is meant by “corridor” ?
The navigation system plans a route and then loads a “belt” around the planned route
(the corridor) as map data from the map CD into the main memory.
Functional restrictions in corridor mode
Please note that some navigation system functions are not or only partially available
when the map CD (corridor mode) is not inserted.
In this event, the menu options appear grey (e.g. Alternative route, Route selection,
Traffic info away from the planned route).
It is only possible to load stored addresses if they are located within the corridor.
Route planning is only possible with roads located within the corridor. Even if a
destination address is located within the corridor and can be entered as a destination,
it may not be possible to plan a route to that destination. In this case, please insert the
map CD.
TMC traffic information is only available for the map region stored in the corridor.
Travel info and POIs can only be called up using the map CD.
Some C-IQ functions (in particular code entry) are only possible when the map CD is
inserted.
✎
As soon as you insert the map CD, these functions are available again.
Leaving the corridor
If you leave the corridor, e.g. if you are not following the planned route, the
navigation system will attempt to guide you back into the corridor. The directional
arrow and the distance to the planned route will be displayed.
When leaving the corridor (more than approx. 3 km), the navigation system will
display only the directional arrow and the distance to the destination.
In this case, please insert the map CD so that the navigation system can plan a new
route to your destination.
