Cause
Possible solution
No image/ black
screen
(manufacturer
image).
Not all plugs have been connected to the stock head
unit or monitor after installation.
Connect the remaining
plugs.
No power supplied to CAN unit (not all CAN-unit
LEDs light up).
Check CAN unit power
supply. Check CAN bus
and CAN unit
connectivity.
CAN unit is connected to CAN bus in a wrong place.
Consult the manual for
correct CAN bus
connection.
No power supplied to the video interface (not all
video interface LEDs light up).
Check whether CAN

manufacturer image
is displayed
incorrectly.
No image from the video source.
Use a different monitor

additional buttons in the
bottom part of the video
interface.
Inserted image is
distorted, flickering
or displayed in black
and white.
Video source output is in AUTO or MULTI mode,
which causes incorrect detection of the car’s
interfaces.
Set the output video
source to PAL or NTSC.
Best of all is to use one
video standard for all
video sources.
If the error occurs only after the video source is
turned on,
Use one video standard
for all video sources.
Some interfaces can process NTSC input only.
Consult the manual for
any NTSC-related
restrictions. If only
NTSC standard is
supported, set the video
source to NTSC output.
Poor quality of
