Route guidance within a partially

Route guidance is provided by means of a
direction arrow showing the compass
heading to the destination. COMAND will
not generate automatic navigation
announcements.
If you try to repeat the current voice
instruction manually, ( page 151) you will
hear the announcement "You are currently
in an area where turn by turn guidance
cannot be provided.".
During route guidance, the display is
divided. On the right-hand side you will see
the direction arrow showing the compass
heading to the destination.
On the left-hand side of the display you will
see the map with the suggested route. The
suggested route is highlighted blue.
However, it may not be possible to follow
the suggested route because, for example,
the road is closed or not open for car
traffic.

If, during route guidance, COMAND leads
you back into a fully digitalized area, route
guidance will simply continue in the usual
manner.
