Route & Sound – Navigating and listening to a CD
With this new generation navigation radio unit, you may insert a map
CD, plan your route, then insert an audio or MP3 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 (corri-
dor) 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.
■
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 are only partially avail-
able when the map CD (Route & Sound mode) is not inserted (e.g. dynamic route plan-
ning, alternative route, route selection, traffic info outside of 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 desti-
nation 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 (Points of Interest) 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 in-
serted.
✎
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 naviga-
tion system will attempt to guide you back into the corridor. The directional arrow
and the distance to the planned route will be displayed.
If you continue travelling away from the corridor, 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.
