Introduction
The digital data for the map software will
become obsolete, just like conventional
road maps. Optimum route guidance by
the navigation system is only achieved
with up-to-date map software. Information
on new map software versions is available
from an authorized Mercedes-Benz Center.
You can have the map software updated
there by means of a DVD or perform the
update process yourself.
Notes on DVD discs

Only touch the discs at the edges.

Handle the discs with care in order to
prevent reading errors.

Avoid scratching, leaving fingerprints
and dust on the discs.

Use a commercially available cleaning
cloth to clean discs. Always wipe in a
straight line from the inside outwards,
never in a circular motion.

After use, put the discs back into the
box.

Protect the discs from heat and direct
sunlight.
Introduction
Safety instructions
G Warning
For safety reasons, only enter a destination
when the vehicle is stationary. When the ve-
hicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing:

Traffic lights

Stop and right-of-way signs

Lane merging

Parking or stopping prohibited areas

Other road and traffic rules and regula-
tions

Narrow bridges
G Warning
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual road/
traffic situation. Digital maps do not cover
all areas nor all routes within an area. For ex-
ample, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.
G Warning
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.
Updating the map software

113 Navigation
Introduction
Update sequence
The sequence includes the following stag-
es:

Loading DVD into the DVD changer

Update process
i The update process may take between 60
and 150 minutes, depending on the size of the
map software.
If possible, perform the update when the vehicle
is stationary. The DVD read speed is faster when
the vehicle is stationary than when the vehicle is
moving and the update therefore takes less time.
If you perform the update with the engine off and
the vehicle battery is no longer powerful enough,
COMAND may shut off automatically during the
process to protect the battery. In this case, re-
start the update with the engine running.
You can interrupt the update process and contin-
ue it at a later time. If you cancel the update pro-
cess, the navigation system is not ready for
operation.
Loading DVD into DVD changer
The DVD changer is a magazine with six
built-in compartments.
1Disc slot

i If the magazine is full, you will first need to
eject a disc (
page 57).
G Warning
Never leave the engine running in an en-
closed space. The exhaust gases contain
carbon monoxide. Inhaling exhaust gases
constitutes a health hazard and could lead
to loss of consciousness or even death.

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.
