Reason
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.
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.
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.
Set interface OSD menu item UI-CNTRL to ALLOFF or
PDCON.
Use external keypad or cut white wire of 6pin to 8pin
cable and apply +12V impulses for AV-switching.
For video source switching a longer press of about 2.5
seconds is required.
Use OEM-button or cut white wire of 6pin to 8pin
cable and apply +12V impulses for AV-switching.
Cut the green wire of the 6pin to 8pin cable and apply
+12V constant from reverse gear-lamp signal. Use
relay to "clean" R-gear lamp power.
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.
