1.4.1.

 

Activating the front camera (dip 1) 

 

If set to ON, the interface switches for 5, 10 or 15 seconds from the rear-view camera to the 
front camera input after having disengaged the reverse gear, depending on the menu 
adjustments. In addition, a manual switch-over to the front camera input is possible via 
keypad (short press) from any image mode. 
 

Description of the power supply output: see chapter “Power supply output

 for front cam

”.

 

 

1.4.2.

 

Enabling the interface’s video inputs (dip 2

-3) 

 

Only the enabled video inputs can be accessed by switching through the interface’s video 

sources. It is recommended to enable only the required inputs. So the disabled inputs will be 
skipped while switching through the video interfaces inputs. 
 

 
1.4.3.

 

Rear-view camera setting (dip 5) 

 

If set to OFF, the interface switches to factory picture while the reverse gear is engaged to 
display factory rear-view camera or factory optical park system picture. 
If set to ON, the interface switches to its rear-view camera input while the reverse gear is 
engaged. 

 
 
1.4.4.

 

Activation of the factory PDC display (Dip 6) 

 

Dip 6 is used to switch between image formats of front and rear camera and to display the 

factory PDC (if available) as „picture in picture“ in combination wit

h the camera image. 

For a detailed description, see chapter "Switching the Camera Image Formats and Factory 
PDC Display ". 

 
 
1.4.5.

 

Monitor selection (Dip 7-8) 

 

Dips 7-8 customize the monitor-specific video settings which sometimes even vary within 
head units of the same version, caused by different monitor specifications. If the mentioned 

dip positions don’t give a satisfying picture, try all possible combinations of dip7 and 8 while 

a working video source is connected to the chosen input of the interface. One of the 4 
combinations will show the best picture size and quality (some may give no picture). It is 
possible to first hot plug through the dip combinations. If there is no change of picture 
visible after trying all 4 options, retry and disconnect the 6pin plug at the interface box 
between every change of the dip setting. 

 
Note:

 Dip 4 is out of function and has to be set to 

OFF
