Introduction The digital maps generated by the map soft-
ware become outdated in the same way as
conventional road maps. Optimal route guid-
ance 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 dig-
ital map updated there with a DVD, or you can
update it yourself.
Carrying out a manual update i
The update process can take a long time
(over an hour), depending on the size of the
digital map. 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 start the update with the engine
switched off and the starter battery has
insufficient power, COMAND may automat-
ically switch off. This protects the battery.
If this occurs, restart the update with the
engine running.
