Symptom 

Reason 

Possible solution 

Camera input picture 
black. 

Camera power taken directly 
from reverse gear lamp. 

Use relay or electronics to "clean" reverse gear lamp 
power. Alternatively, if CAN-bus box is compatible 
with the vehicle, camera power can be taken from 
green wire of 6pin to 8pin cable. 

Camera input picture 
has distortion. 

Camera input picture 
settings cannot be 
adjusted. 

Camera input picture settings 
can only be adjusted in AV2 
mode. 

Set dip 3 of video-interface to ON (if not input AV2 is 
not already activated) and connect the camera to AV2. 
Switch to AV2 and adjust settings. Reconnect camera 
to camera input and deactivate AV2 if not used for 
other source. 

Graphics of a car in 
camera input picture. 

Function PDC is ON in the 
interface OSD. 

In compatible vehicles, the graphics will display the 
factory PDC distance. If not working or not wanted, set 
interface OSD menu item UI-CNTRL to ALLOFF. 

Chinese signs in 
camera input picture 

Function RET or ALL is ON 
(function for Asian market) in 
the interface OSD. 

Set interface OSD menu item UI-CNTRL to ALLOFF or 
PDCON. 

Not possible to switch 
video sources by OEM 
button. 

CAN-bus interface does not 
support this function for 
vehicle. 

Use external keypad or cut white wire of 6pin to 8pin 
cable and apply +12V impulses for AV-switching. 

Pressed too short. 

For video source switching a longer press of about 2.5 
seconds is required.  

Not possible to switch 
video sources by 
external keypad. 

SW-version of interface does 
not support external keypad.  

Use OEM-button or cut white wire of 6pin to 8pin 
cable and apply +12V impulses for AV-switching. 

Interface does not 
switch to camera input 
when reverse gear is 
engaged. 

CAN-bus interface does not 
support this function for the 
vehicles. 

Cut the green wire of the 6pin to 8pin cable and apply 
+12V constant from reverse gear-lamp signal. Use 
relay to "clean" gear lamp power. 

Interface switches 
video-sources by itself. 

CAN-bus interface 
compatibility to vehicle is 
limited.  

Cut the grey wire of 6pin to 8pin and isolate both 
ends. If problem still occurs, additionally cut the white 
wire of 6pin to 8pin cable and isolate both ends.
