Introduction
An unsuccessful update may be caused by
one of the following:

DVD dirty or scratched.
Clean the DVD.
Please refer to the “Notes on DVD
discs” section (
page 112).
Restart the update.

Overheating as a result of excessively
high temperatures in the passenger
compartment.
Wait until the passenger compart-
ment has cooled down.
Restart the update.

The memory medium (hard drive) inte-
grated into COMAND has a physical de-
fect.
Contact an authorized
Mercedes-Benz Center.Operational readiness of the navigation
system after the system software up-
date
Sometimes the installed map software is
no longer compatible following a system
software update by an authorized
Mercedes-Benz Center. In this case, the
navigation system is not operational.
To update map software: Proceed as
described in the “Update process” sec-
tion (
page 114). Use map software
compatible with the system software.
i Please note that in this case the update
must run through right to the end. If you cancel
beforehand, the navigation system will still not
be ready for operation.
After start-up or initial start-up, the naviga-
tion system must perform a position find-
ing operation. As a result, you may have to
drive for some time until precise route
guidance takes place.
GPS reception
The correct functioning of the navigation
system is also dependent on the GPS re-
ception. In certain situations, the GPS re-
ception may be impaired, distorted or even
impossible, e. g. in tunnels, multi-storey
car parks or due to snow on the GPS anten-
na. If there is snow on the GPS antenna,
you should remove it. The GPS antenna is
at the rear on the vehicle’s roof.
Route guidance after vehicle transport
After vehicle transport (e. g. by ferry, car
train or by towing) COMAND must deter-
mine the vehicle location again.
Position finding takes place automatically
when the vehicle is driven off again, even if
COMAND is switched off. The actual length
of time may vary from case to case.
While the vehicle is determining its posi-
tion, route guidance is subject to the fol-
lowing restrictions:

Navigation announcements, route
guidance displays and displayed street
names do not match the actual loca-
tion.
General information

116 Navigation
Introduction

COMAND does not issue any naviga-
tion announcements.

The message “Off Mapped Road” and a
direction arrow are displayed instead
of the route guidance displays. The ar-
row indicates the direction of the desti-
nation.
i Direction arrow accuracy is also dependant
on correct vehicle position and/or direction.
Once the position finding operation has
been completed, route guidance takes
place again via navigation announcements
and route guidance displays.
Interrupting journey during route guid-
ance
i An interruption in the journey means parking
the vehicle and switching off COMAND.
The continuation of the journey means switching
COMAND on again and continuing to drive.
If you interrupt the journey during route
guidance and continue it later, the follow-
ing applies:

If you continue the journey within
2 hours, COMAND automatically con-
tinues route guidance.

If you continue the journey after
2 hours, route guidance is cancelled.
You will have to continue the cancelled
route guidance again manually
(
page 154).
Hard disk drive
COMAND has an integrated hard drive on
which the map software is stored.
If an area of the hard drive has a fault,
COMAND can no longer access the map
data in that area for the route calculation,
for example.
The message “Navigation Unavailable” will
then be displayed.
To delete message: Switch COMAND
off and back on again.
i After switching on/off, the navigation sys-
tem will remain functional until it has to access
the faulty area of the hard drive again. The mes-
sage will be displayed again.
Contact a Mercedes-Benz service center.
Measurement units
The measurement units displayed in navi-
gation mode are identical to those set in
the instrument cluster.There is an input restriction for vehicles for
certain countries.
The restriction is active for vehicle speeds
above apprx. 3 mph. The restriction is de-
activated as soon as the speed falls below
apprx. 2 mph.
Certain entries cannot be made when the
restriction is active, e. g. a city or road en-
try.
This is indicated by the fact that certain
menu items cannot be selected.
