Audio-switch and audio insertion
This interface can only insert video signals into the factory infotainment and switch audio
signals. If an AV-source is connected to AV1 or AV2, audio insertion must be done by factory
audio AUX input, the optionally available AUX-in interface AUX-110 (only for MMI3G, not for
MMI3G+)or FM-modulator to which the interface’s sound-switch output is connected. When
the interface is switched from AV1 to AV2, the audio signal is switched parallel to the
corresponding video signal by the interface’s built-in audio-switch. The inserted video-signal
can be activated simoultaneously to each audio-mode of the factory infotainment.
Note:
If no factory AUX-input is available, it is possible to code it with the optionally
available OBD-coder OBD-MMI3G-HM-xx.

Note:
If only one AV-source shall be connected, it is possible to connect the video output of
the AV-source to the video input AV1 of the video-interface and the audio output of the AV-
source directly to the point of audio-insertion (e.g. audio AUX input).
Connect female 7pin connector of the audio cable to male 7pin connector of the
video-interface.
Connect the audio-RCA of the possibly existing factory AUX-input, the AUX-110 or the
FM-modulator to the female RCA port AV-Out of the audio cable.
Connect the audio-RCA of the AV-source 1 to the female RCA port AV1 of the audio
cable.
Connect the audio-RCA of the AV-source 2 to the female RCA port AV2 of the audio
cable.
