COMAND navigation (introduction)
General notes
Operational readiness of the navigation
system following a system software
update by an authorized
Mercedes-Benz Center
After a system software update by an au-
thorized Mercedes-Benz Center, the in-
stalled map software may no longer be
compatible. If this is the case, the naviga-
tion system will not be operational.
You will know if this is the case, when the
following message will appear when you
switch to navigation mode: “The system
software has been updated. The map soft-
ware must be updated now. Please insert
the DVD with the map software.”
Updating map software: Proceed as
described in the “Updating the map
software” section (
page 159). Use
map software which is compatible with
the system software.Initial use or use following a system
software update
In both these cases, the navigation system
must determine the position of the vehicle.
You may have to drive for a while before
precise route guidance is possible.
GPS reception
Correct functioning of the navigation sys-
tem depends on GPS reception, among
other things. In certain situations, GPS re-
ception may be impaired, there may be in-
terference or there may be no reception at
all, e.g. in tunnels, in multistory parking ga-
rage or due to snow on the GPS antenna. If
there is snow on the GPS antenna, you
should remove it. The GPS antenna is at
the back of the vehicle roof.The roof cargo container* may also impair
mobile phone reception and GPS cover-
age.
Route guidance after vehicle transpor-
tation
COMAND has to redetermine the position
of the vehicle if the vehicle has been trans-
ported (e.g. by ferry, by train or after tow-
ing).
Positioning takes place automatically even
when COMAND is switched off. The dura-
tion varies from one case to another.
Route guidance may be restricted as fol-
lows during vehicle positioning:

Navigation announcements, route
guidance displays and displayed street
names are not consistent with the ac-
tual location of the vehicle.

COMAND does not generate navigation
announcements.
iPlease note that the update must be allowed
to run to the end in this case. If you interrupt it,
the navigation system will continue to be non-op-
erational.

Warning!G
Some jurisdictions prohibit the driver from
using a cellular telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approxima-
tely 14 m) every second.
Warning!G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.
