Audio-insertion 

 

This interface is only able to insert video signals into the factory infotainment. If an AV-
source is connected, the audio insertion has to be done by the factory audio AUX input or an 
FM-modulator. The inserted video-signal can be activated simultaneously to each audio-
mode of the factory infotainment. If 2 AV sources shall be connected to the infotainment, 
additional electronic is necessary to switch the audio signals.

Picture settings and guide lines 

 
 

 

 
 
The picture settings are adjustable by the 3 push-buttons at the rear-side of the video-
interface. Press the MENU button to open the OSD settings menu or to switch to the next 
menu item. Press UP and DOWN to change the selected value. The buttons are placed inside 
in the housing to avoid accidental changes during or after the installation. Picture settings 
must be done separately for all video inputs while the corresponding input is selected and 
visible on the monitor. 
 

Note: 

The OSD menu is only shown when a working video source is connected to the 

selected video-input of the interface.
