2.5.2. 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, the audio insertion has to be done by
the factory audio AUX input or a 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 simultaneously to each audio-mode of the factory
infotainment.
Note:
If 2 AV sources shall be connected, the optionally available audio switch SW-A2X1 has
to be connected. While the interface is switched from AV 1 to AV 2, the audio signal will
automatically be switched to the right source.
Connect the interface cable’s female 20pin connector to the male 20pin connector of
the video-interface.
Connect the interface cable’s drilled pink- and black-coloured wires to the audo
switches power input. Connect the pink wire to the input “BATT” and the black one
to the grey wire beside.
Connect the audio-RCA of the AV-source 1 and the AV source 2 to the female RCA
port “AUDIO-IN1” and “AUDIO-IN2” of the audio switch.
Connect the audio-RCA of the factory-audio-AUX-input or the FM-modulator to the
female RCA port “AUDIO-OUT” of the audio switch.
