0050Solutions COMAND is unable to
continue route guid-
ance after the journey
has been interrupted. Route guidance is canceled if you interrupt the journey for more
than two hours.
"Interrupting the journey" refers to stopping the vehicle.
"Continuing route guidance" refers to switching COMAND back on

Possible causes/consequences and
0050 0050Solutions COMAND is unable to
determine the vehicle's
position. COMAND has to redetermine the position of the vehicle if the
vehicle has been transported.
Example:
R After transporting the vehicle by ferry
R After transporting the vehicle by motorail
R After the vehicle has been towed
X Start the vehicle and pull away.
COMAND determines the vehicle's position. Depending on the
driving situation, this may take some time.
Route guidance may be restricted during the determination of
the vehicle's position.
When positioning is complete, route guidance is resumed with
navigation announcements and route guidance displays. Navigation
