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
2Load button
Press the Load button2.
A menu indicates which magazine com-
partments are currently loaded.
To select an empty magazine com-
partment: Rotate ymz or slide omp.

The message “Please Insert Disc ”
will then be displayed.
Insert the DVD into the slot1 with the
printed side upwards.
The DVD changer pulls in the DVD. The
message “Loading Disc ...” will be
displayed.
i If the magazine is full, you will first need to
eject a disc (

148 Navigation
Route guidance
COMAND guides you to the destination by
means of driving recommendations in the
form of navigation announcements or
route guidance displays.
i The route guidance displays only appear if
the display has been switched to navigation
mode.
If for some reason you do not follow the
driving recommendations or leave the cal-
culated route, COMAND automatically cal-
culates a new route to the destination.
If the map data contains corresponding in-
formation during route guidance
COMAND tries to avoid roads with limited
passability, e. g. roads that are blocked for
through-traffic and are for residents only.
Time restrictions of roads (e.g. blocked on
Sundays and public holidays) are only tak-
en into account for route guidance if the
digital map contains corresponding infor-
mation during the blocked time periods.Driving maneuvers are given in three phas-
es:

Preparation phase

Announcement phase

Maneuver phase
Route guidance
General information
G Warning
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
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 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.

Overview
Operating Safety
G Warning
Please devote your attention first and fore-
most to the traffic situation you are in. While
the system permits hands-free phone oper-
ation, attention to traffic may be diverted
not only by physical operation of a phone,
but also by the distraction of a phone con-
versation while driving. As such, for safety
reasons, we encourage the driver to stop the
vehicle in a safe place before answering or
placing a phone call.
For safety reasons, you should only select a
destination when the vehicle is stationary.
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their ob-
servance always remains in the driver’s per-
sonal responsibility. DVD maps do not cover
all areas nor all routes within an area.
Traffic regulations always have priority over
any route recommendations given.
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 13.5 m) every second.
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.
G Warning
Please do not use the Voice Control System
in an emergency, as the tone of your voice
may change in a stressful situation. This
could cause a delay in completing your
phone call in a timely manner. This could
distract you in an emergency situation and
cause you to be involved in an accident.
