Updating the digital map
Introduction
The digital maps generated by the map
software become outdated in the same way
as conventional road maps. Optimal route
guidance can only be provided by
the navigation system in conjunction with the
most up-to-date map software.
Information about new versions of the digital
map can be obtained from an authorized
Mercedes-Benz Center. You can have the
digital map updated there with a DVD, or you
can update it yourself.
i The update process can take a long time
(over an hour), depending on the size of the
map software. During this time, you will
only be able to switch on radio mode and
to accept incoming calls. The update will be
completed more quickly if the vehicle is
stationary.
If you carry out the update with the engine
switched off and the starter battery has
insufficient power, COMAND may
automatically switch off during the process
in order to protect the battery. If this
occurs, restart the update with the engine
running.
G WARNING
Never run the engine in an enclosed space.
The exhaust fumes contain poisonous carbon
monoxide. Inhaling exhaust fumes is
hazardous to your health and can lead to loss
of consciousness and death.
Updating process
X
Insert the DVD (

page 127).
The update begins. COMAND checks
whether the digital map on the DVD is
compatible with the navigation system and
system software.
If this is the case and the DVD's map data
has not already been installed, COMAND
starts updating the digital map.
If the map data has already been installed,
the display shows version data and a
message to this effect.
X To confirm the message: press the 9
button.
X Eject the DVD.
While the update is running, you will see a
message to this effect and a progress bar. The
