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 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 simultaneously to each audio-mode of the factory
infotainment.

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 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.
