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.

 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). 

 

Connect female 7pin connector of the audio cable to male 7pin connector of the 

video-interface. 

 

Connect the audio-RCA of the possibly exis

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.
