Rearviewcamera activation
When put gear in Reverse the interface switches automatically
to Reverse camera input, usually detected by CANbus system of the car.
Unfortunately sometimes reverse it's not reacting by CANbus because the car
can have different CAN protocol/codes.
Also the guide lines can not be guaranteed.
In this case the reverse trigger wire of the interface should be connected with
the analog reverse licht signal like shown below.
When Reverse is NOT reacting by CANbus:
If the reverse light is LED, use a relay like this:
Pin 30 → +12V ignition
Pin 85 → GROUND
Pin 86 → LED reverse light
Pin 87 → Green wire of
the interface
with label
“Reverse IN”

Troubleshooting
When you DON’T have OEM image
(only black screen with sound of the radio)
#1 Please check the LVDS cable
#2 Please check the power 7supply of the interface
Installation with CANBUS:
Yellow wire has +12 Volt ?
Installation WITHOUT CANBUS:
Yellow and purple wire has +12 Volt ?

Troubleshooting
When you have OEM image.
After putting in reverse, nothing is happening
(no rearviewcamera image, it stays in OEM image)
#1 Please check the green wire (“Reverse IN”)

14
#3 Please check your dipswitch 5 (dip 8 settings)
Must be down (ON)

15
Troubleshooting
When you have OEM image, but no rearviewcamera image.
After putting in reverse, it switch to black image.
#1 Check the power supply of the rearviewcamera

16
#2 Check camera input of the interface
#3 Power supply of the rearviewcamera
Do NOT connect the powercable of the rearviewcamera to the reverselight.
This 12V is NOT stable, most of the cars have “duty circle” in the 12V reverselight.
We suggest to find a stable 12V in the fusebox.
To extend the service life of the rearviewcamera, we recommend a ignition 12 Volt.

Troubleshooting
Rearview image adjustment
When you have black/grey border in the rearview image

left ←or right →
Adjust “position V”
