Limitations
Video only The interface inserts ONLY video into the infotainment.
For sound use the possibly existing factory-audio-AUX-input, a
FM-modulator or the AUX-in interface AUX-110.
Factory OPS Display of an optical park display (OPS) isn’t possible if an
after-market rear-view camera is connected and reverse gear is
engaged. Acoustic signals are still existing.
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.
1.2. Checking the compatibility of vehicle and accessories
1.3. Boxes and connectors
1.3.1. CAN-box
The CAN-box reads digital signals from the CAN-bus and converts them for the video-
interface.

Version 21.02.2017 CI-VL2-MMI3G-xxx

1.3.2. Video-interface
The video-interface converts the connected after-market sources video signals to an LVDS
signal which is the inserted into the factory monitor on certain trigger options.
1.3.2.1. 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.
1.3.2.2. Enabling the interface’s video inputs (dip 1-3)
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.

1.3.2.3. RGB-video input signal selection for after-market navigation (Dip 4)
If an after-market RGB navigation or other RGB video source is connected, the source’s RGB
output signal must match the interface’s RGB video input setting.
1.3.2.4. 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.
1.3.2.5. Monitor selection (dip 7-8)
Dip 7 and 8 are for monitor-specific video settings which cannot be predicted as even within
the same head-unit version, the monitor specifications may vary. It is necessary to try all
possible combinations (both OFF, both ON, 7 OFF and 8 ON, 7 ON and 8 OFF) - while a
working video source is connected to the chosen input of the interface - to see which
combination gives the best picture quality and size (some may give no picture). It is possible
to first hot plug through the dip combinations, but if you do not experience any change of
picture after trying all 4 options, retry and disconnected the 6pin power plug of the video-
box between every change of the dip setting.

2. Installation
Switch off ignition and disconnect the vehicle’s battery! The interface needs a permanent
12V source. If according to factory rules disconnecting the battery is to be avoided, it is
usually sufficient to put the vehicle is sleep-mode. In case the sleep-mode does not show
success, disconnect the battery with a resistor lead.
If power source is not taken directly from the battery, the connection has to be checked
for being start-up proven and permanent.
2.1. Place of installation
The interface is installed on the backside of the head-unit (navigation computer/radio).
Depending on the version of the interface the connection to CAN-Bus and power is different:

2.3. Connecting Video-interface and CAN-box
Note: It is possible to use the interface without MMI-box. In this case sort the female 8pin
connector out from the 6pin to 8pin cable.
Connect white female 4pin Micro-Fit connector of the PNP power/CAN cable to the
male 4pin Micro-Fit connector of the CAN-box.
Connect white female 6pin connector of the 6pin to 8pin cable to the male 6pin
connector of the video-interface.
Connect black female 8pin Micro-Fit connector of the 6pin to 8pin cable to male 8pin
Micro-Fit connector of the MMI-box.
Note: Check LEDs on video-interface after reconnecting the battery, one must be on.
Connect the separate white cable to MMI signal –only for alternative switching of
sources by NAV button in the centre console, if existing. (only for MMI 3G, not for
MMI 3G+ or RNS850).
Connect the female 8pin connector of the6pin to 8pin cable`s drilled communication
cable to the male 8pin connector of the MMI box
