Setting the speed-dependent vol-
ume control (SVC)
This function automatically adjusts the volume
of the car sound system to the speed driven
and the associated driving noises. For
example, as the driving speed increases, the
volume is automatically increased to compen-
sate for the louder driving noise (e.g. due to
the airflow).
For this purpose, the vehicle must provide the
speedometer signal, and the car sound system
must be connected accordingly.
The automatic increase in volume can be
adjusted in 6 increments (OFF, 1-5).
