Audio device features
These Operating Instructions describe all
standard and optional equipment available
for your audio device at the time of going to
print. Country-specific deviations are
possible. Please note that your audio
equipment may not offer all the features
described. This includes safety-related
systems and functions. The equipment in
your vehicle may therefore differ from some
of the descriptions or illustrations.
The original purchase agreement lists all
systems installed in your vehicle. Contact an
authorized Mercedes-Benz Center if you have
any questions about equipment or operation.
Function restrictions
For safety reasons, some Audio 20 functions
are restricted or unavailable while the vehicle
is in motion. You will notice this, for example,
because you will either not be able to select
certain menu items or because Audio 20 will
display a message to that effect.
