Updating the map software
You can update the map software yourself
using a DVD.
Notes about handling DVDs

Only hold discs by the edge.


Handle discs carefully to prevent read
problems.


Avoid getting scratches, fingerprints
and dust on discs.


Use a commercially-available cleaning
cloth to clean discs. Do not wipe them
with a circular motion, but only in
straight lines from the center out-
wards.


Place discs back in their boxes after
use.


Protect discs from heat and direct sun-
light.
Updating process
The updating process has the following
phases:

Loading a DVD into the DVD changer
(page 142)


Updating process (
page 142)
i
The updating process can take between 10
and 60 minutes, depending on the size of the
map software. If the radio was switched on be-
fore you started the updating process, you can
still adjust the volume. You can also use
COMAND to operate the automatic air condition-
ing and to cancel the process. Other functions
are not operational.
If possible, carry out the update when the vehicle
is stationary.
i
If you carry out the update with the engine
switched off and the vehicle battery has insuffi-
cient power, COMAND may automatically switch
off during the process in order to protect the bat-
tery. If this occurs, restart the update with the
engine running period. Similarly, if the SmartKey
position is unintentionally switched to 0, restart
the update.Warning!
G
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.

185 Control systems
COMAND navigation system (route guidance)
COMAND navigation system (route guidance)
Route guidance
COMAND guides you to the destination us-
ing navigation commands in the form of
audible navigation announcements and
route guidance displays.
If, for any reason, you do not follow the
navigation commands or if you leave the
calculated route, COMAND automatically
calculates a new route to the destination.
If the map data contains the relevant infor-
mation, COMAND tries to avoid roads that
only have limited access, e.g. roads closed
to through-traffic and non-residents.Roads that have time restrictions (e.g.
closed on Sundays and public holidays) are
not considered for route guidance, if the
digital map contains the relevant informa-
tion.
Examples of displays and announce-
ments for a driving maneuver
Driving maneuvers have three phases:

Preparation phase


Announcement phase


Maneuver phase
Warning!
G
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing, for example:

Traffic lights


Stop and right-of-way signs


Parking or stopping prohibited areas


Lane merges


Other road and traffic rules and regula-
tions


Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual
road/traffic situation. For example, if the
traffic routing has been changed or the di-
rection of a one-way road has been re-
versed.
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.i
The route guidance displays can only be
seen if the display is switched to navigation
mode.

188 Control systemsCOMAND navigation system (route guidance)Partially digitized areas If the destination is within a partially
digitized area
COMAND guides you through fully digitized
areas for as long as possible. Route guid-
ance is conducted in the usual manner, i.e.
with navigation announcements and route
guidance displays.
Before the vehicle reaches a partially digi-
tized area, COMAND notifies you of this
with the following announcements:


“Be prepared to enter an area where
turn by turn guidance cannot be provid-
ed.”


“In 700 feet you will enter an area
where turn by turn guidance cannot be
provided.”


“You are about to enter an area where
turn by turn guidance cannot be provid-
ed.”Route guidance within a partially digi-
tized area
If you start route guidance in this type of
area, you will hear the following announce-
ment: “You are currently in an area where
turn by turn guidance cannot be provided.”
Route guidance is provided by means of a
direction arrow showing the compass
heading to the destination. COMAND will
not generate automatic navigation an-
nouncements.
If you try to call up an announcement man-
ually, (
page 191) you will hear the an-
nouncement “You are currently in an area
where turn by turn guidance cannot be pro-
vided.”.
i
The digital map may contain areas that are
only partially digitized although they are within a
digitized region.Warning!
G
Due to incomplete digitization, the route
shown on the map may differ from the actual
road/traffic situation.
If you follow the route shown on the map, for
example, it is possible that you could drive
the wrong way down a one-way street or
that a street cannot be driven on.
When using route guidance in a partially dig-
itized area, you must therefore be sure to
observe all relevant traffic regulations and
the course of the road.
All relevant traffic regulations and the
course of the road always take priority over
the route shown on the map.
i
The indicated distance can be seen here by
way of example. In reality, it may be different.
i
When you call up the route info to this type
of destination, (
page 193) the following data
shown there may differ from the actual situation:


Distance to the destination


Estimated driving time to the destination


Estimated arrival time

189 Control systems
COMAND navigation system (route guidance)
During route guidance, the display is divid-
ed. 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. How-
ever, 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.
Off-road and off-map
Route guidance to an off-road destina-
tion
COMAND can guide you to destinations
within the area covered by the digital map,
even if a destination is not located at a
road known to the system.These destinations are shown as off-road
destinations, which you can enter using
the map, for example.
In these cases, COMAND guides you for as
long as possible with navigation announce-
ments and displays on roads known to the
system.
Shortly before you reach the last known
the point to leave the digitized road net-
work, you will hear the announcement “The
destination is nearby. Follow the arrow on
the display”.
You will then see an arrow that indicates
the direction to the off-road destination.
When the off-road destination is close to
the road, “Area of dest. reached” appears
in addition below the arrow.
The section of the route from the last
known point on the map to the off-road
destination is indicated with a dashed line
after a certain length. It simply shows the
direction to the off-road destination with-
out taking account of any type of obstacles
in the way.Warning!
G
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of traversing through without
damaging your tires, wheels or vehicle. It is
the driver’s sole responsibility to determine
the suitability of the route. Off-road routes
may be of varying conditions and their ap-
propriateness for use may be affected by
various factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into consider-
ation by the COMAND system.

Warning!
G
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.i
If Russian or Chinese is set as the system
language, the navigation announcements are in
English. You will find how to set the system lan-
guage on (
page 216).
Navigation announcements are muted during
telephone calls. You can, however, call up a cur-
rent announcement at any time. You can also
call up a current announcement at any time if
you have missed an announcement.
