offers the best reception as the vehicle travels from one area to the
next. As a result, regional programmes may be interrupted.

the selected frequency until reception is lost. RDS REG

offers the best reception as the vehicle travels from one area to the
next. As a result, regional programmes may be interrupted.
FIX: The unit only changes to regional alternative frequencies for
the current station broadcasting the same regional service. The radio
will accept the frequencies of other stations, only when the reception
quality is very poor.

text information. The individual radio station is responsible for the texts
displayed.

the reception is strong enough, radio text is displayed in the centre

Adjusting the output volume ( AUX/MDI VOLUME LEVEL)
If you need to increase the output volume for the external audio source, first
lower the base volume on the radio system ⇒ page 11.
If the sound from the external audio source is too low, if possible, increase
the output volume on the external audio source. If this is not sufficient, set
the input volume (AUX VOL LEVEL) in the system settings to level 2 or level 3.
If the sound from the connected external audio source is too loud or distor-
ted, if possible, lower the output volume on the external audio source. If
this is not sufficient, set AUX VOL LEVEL to level 2 or level 1.
Speed-dependent volume adjustment
The GALA function automatically adjusts the volume in line with the speed
of the vehicle.
You can set the degree to which the volume increases with speed on a scale
between 1 and 7.
