Problem Possible cause/consequence Suggested solution
You want to
enter a city,
street or city
center but
you have to
spell the
entry. Entering part of an address has failed
after several attempts, e.g. due to
background noise, or you have tried
to enter an address in Puerto Rico
(Y page 220). X
Spell the entry. You have
entered a
phone
number as a
string
but
the
Voice
Control
System does
not
understand
you. X
Speak the phone number in groups
of digits, e.g. three to five digits
each. Voice Control System
individualization
i The individualization can only be
performed when the vehicle is stationary.
If you

drive off, the individualization will be
canceled.
After starting the session, the system will
guide you through the individualization by
means of acoustic instructions.
The individualization is used to adapt the
Voice Control System to your own voice and
to therefore improve speech recognition. This
does not affect the speech recognition of
other users.
Individualization consists of two stages:
R Digits
R Commands
You can activate individualization in the
COMAND system settings (Y page 80). A
dialog and screen displays will guide you
through the individualization process. The system can be reset to the factory
settings at any time.
i
You may wish to complete only a portion
of the individualization process.
Completing the digits portion alone may
result in an improved recognition rate.
Individualization can
be exited at any time.
The data trained, however, will only be
retained if a given individualization portion
is completed and the data is stored when
prompted to do so by the system. 250
