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 inser
ti
on 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 ac
ti
vated simoultaneously to each audio-mode of the
factory infotainment.
Depending whether the vehicle is equipped with a factory media interface, the factory AUX
connec
ti
ons for audio inser
ti
on needs to be done in di
ff
erent ways which are described in
the sub chapters.

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-inser
ti
on (e.g. audio AUX input).
