External audio source
You can connect an external audio source that is operated on the source itself rather than on the PCM to the AUX interface of the PCM.
Accident hazard. The distraction could result in you losing control of the vehicle.
Calling up the main menu for the external source
In order that a connected external audio source can be selected by the button, the interface in the SET menu must be activated.
The external audio source cannot be operated on the PCM, it can only be operated on the device itself. Please consult the operating instructions for the respective device to find out how to do this.
Volume control should mainly be performed
on the external audio source to avoid large
differences in volume (particularly increases)
when changing the audio source.
