Setting the speed-dependent vol-
ume adjustment (GALA)
This function automatically adjusts the volume
of the car sound system to the speed driven
and the associated driving noises. For
example, at an increased speed, the volume is
automatically increased to compensate for the
increased driving noise (e.g. due to the
airstream).
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).
