Caller ID
The audio system can display the telephone
number and the name of the caller, e. g. for
an incoming call and also in other menus or
displays.
For the telephone number to be displayed,
the caller must transmit their telephone num-
ber. Otherwise Unknown will be shown on the
audio display.
This is also the case for name displays. For
this, the telephone number and the name of
the caller must also be saved in the telephone
book.
