The route to cover can also be blocked manually to force a new route to becalculated ⇒ page 39.
TMC traffic reports on the map
Icon: meaning: queues: traffic jam: accident: slippery ground: danger of skidding: danger: roadworks: strong wind: road closed
During guided navigation, traffic incidents that affect the calculated routeare represented in red, while those that do not are represented in grey.
The length of a traffic incident along the route calculated is represented bya red line.
The TMC symbol is located at the start of the traffic delay, provided it hasbeen defined clearly in the TMC traffic report.
Depending on the scale of the map, other congestion icons may be hiddenbehind one TMC icon. In this case, press the TMC icon and a list will openwith further traffic incidents present.

Guide to the destination in demonstration mode (Demo)
If, in the menu Navigation setup, Demo mode is active ⇒ page 44, an addi-tional pop-up window will appear when guided navigation starts.
●
Pressing the function button Demo mode starts a “virtual” guided naviga-tion to the final destination indicated.
●
If you press the function button Normal mode, the “real” guided naviga-tion will begin.
The sequence of events and the operations in virtual route guidance aresimilar to those in real route guidance.
Virtual route guidance is repeated when you reach the fictitious destinationand always starts again from the starting point if it is interrupted.
If in the menu Navigation setup the starting point of the Demo mode was de-termined manually, the virtual guided navigation will begin from this posi-tion.
If the vehicle is moved and the unit can determine its current location byGPS, any manually entered starting point will be overwritten with the currentvehicle location.
When real route guidance is started following virtual route guidance indemo mode, the unit first has to reorient itself. This orientation can lastsome time depending on the number of satellites that are received at thattime. Moving the vehicle may speed up the reorientation process.
Note
Deactivate the Demo mode after use, because otherwise before starting gui-ded navigation you will always have to select whether you want virtual orreal navigation.
