Functional mode description of speed-dependent volume adjustment(GALA)
The GALA function automatically adjusts the volume in line with the speedof the vehicle.
The degree to which the volume increases with speed (GALA) is set on ascale between 1 and 7.
If a low value is set, the volume rises only slightly as the speed of the vehi-cle increases. At a high setting the volume is increased more. At 0, speed-dependent volume adjustment is switched off.
