dual-view monitors!
Limitations
Video only The interface inserts ONLY video signals into the infotainment.
For audio insertion a factory audio-AUX input or FM-modulator
is required. For AUX option coding we offer OBD-N45-X-01.
Factory media interface If available, its AUX cable with 3.5mm jack (available at MB), can
be used for audio insertion. While used for audio insertion, the
Apple adapter or USB adapter cannot be used simultaneously.
Factory rear-view camera Automatic switch-back from inserted video to factory rear-view
camera only while reverse gear is engaged. To delay the switch-
back time, additional electronics is required.
PDC and guidelines If the video interface does not receive the required information
from the vehicle CAN-bus, neither guide-lines nor optical PDC
display will be supported.
1.2. Checking the compatibility of vehicle and accessories
Version 11.05.2021 HW CAM(V31),(V22) CI-RL2-MBN45

1.3. Boxes and connectors
1.3.1. CAN-bus box
The CAN-bus box reads digital signals from the vehicle’s CAN-bus and converts them for the
video-interface.
1.3.2. Video-interface
The video-interface converts the video signals of connected after-market sources in a factory
monitor compatible picture signal which is inserted in the factory monitor, by using separate
trigger options. Further it reads the vehicle’s digital signals out of the vehicle’s CAN-bus and
converts them for the video interface.

1.4. Dip-switch settings
Some settings must be selected by the dip-switches on the
video interface. Dip position down is ON and position up is OFF.
See following chapters for detailed information.
1.4.1.1. Enabling the interface’s video inputs (dip 2-3)
Only the enabled video inputs can be accessed when switching through the interface’s video
sources. It is recommended to enable only the required inputs for the disabled will be
skipped when switching through the video interfaces inputs.
1.4.1.2. Rear-view camera setting (dip 5)
If set to OFF, the interface switches to factory LVDS 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 witches to its rear-view camera input CAM while the reverse gear
is engaged.
1.4.1.3. Monitor selection (dip 7-8)
Dips 7 and 8 customize the monitor-specific video settings which sometimes even vary
within head units of the same version, caused by different monitor specifications. It is
necessary to try all possible combinations while a working video source is connected to the
chosen input of the interface (both OFF, both ON, 7 OFF and 8 ON, 7 ON and 8 OFF). One of
the 4 combinations will show the best picture size and quality (some may give
no picture/black 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 of the video intzerface between every change of the dip setting.
After each Dip-switch-change a power-reset of the Video Interface has to be performed!

2. Installation
To install the interface, first switch off the ignition and disconnect the vehicle’s battery.
Please read the owner`s manual of the car, regarding the battery`s disconnection! If
required, enable the car`s Sleep-mode (hibernation mode)
In case the sleep-mode does not succeed, the disconnection of the battery can be done
with a resistor lead.
If the necessary stabilized power supply for the interface is not taken directly from the
battery, the chosen connection has to be checked for being constantly stabile.
The interface needs a permanent 12V source!
2.1. Place of installation
The interface shell be installed on the backside of the factory monitor and head-unit.

2.3. Connection - video-interface and CAN-box
The CAN-bus box reads digital signals from the CAN-bus and converts them for the video-
interface. ACC +12V max. 0.5A (red of 6pin) and reverse gear +12V max. 0.5A (green of 6pin)
constant signal. Video-source switching (white of 6pin) as +12V impulse.
Connect theblack female 10pin connector of the Quadlock harness to the male 10pin
connector of the CAN-box.
Connect the white female 6pin connector of the 6pin to 8pin cable to the male 6pin
connector of the video-interface.
Connect the black female 8pin connector of the 6pin to 8pin cable to the male 8pin
connector of the CAN-box.
Note: Check the LEDs on CAN-box after reconnecting the battery, two must be on.
Not all vehicles are kompatible. If the CAN-box does not deliver ACC to pin2 of the video-
interface or blocks the thevehicle’s CAN, it is possible to install the video interface without
the CAN-box. In this case see also note in chapter after-market rear-view camera if one is
supposed to be connected.

2.4. Connection - factory monitor
Remove factory monitor.
Remove the blue female 4pin HSD connector from the rearside of the factory
monitor and connect it to the aubergine colored male 4pin HSD connector of the
picture signal cable.
Connect the waterblue colored female 4pin HSD connector of the picture signal cable
to the white male 4pin HSD connector of the factory monitor.
Connect the waterblue colored female HSD+2 connector of the picture signal cable
to the male HSD+2 connector of the video-interface.
Note: No liability for vehicle wire colours and pin definition!
Changes by the vehicle manufacturer are possible. The given information has to be verified
