Audio-switch and audio-insertion
This interface is only able to 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.
