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.

2.6.1. Audio-switch and audio insertion
This interface can only insert video signals into the factory infotainment and switch audio
signals. If an AV-source is connected to AV1 or AV2, audio insertion must be done by factory
audio AUX input or FM-modulator to which the interface’s sound-switch output is
connected. When the interface is switched from AV1 to AV2, the audio signal is switched
parallel to the corresponding video signal by the interface’s built-in audio-switch.
The inserted video-signal can be activated simoultaneously to each audio-mode of the
factory infotainment.

2.6.2. After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the included CAN-
box is not compatible with. Therefore there is two different ways of installation. If the CAN-
box can detect the reverse gear in the vehicle, the green wire of the 6pin to 8pin cable
should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before testing.
2.6.2.1. Case 1: CAN-box detects reverse gear
If the CAN-bus interface delivers +12V on the green wire of the 6pin to 8pin cable when
reverse gear is engaged, the video interface will automatically be switched to the rear-view
camera input CAM while reverse gear is engaged.
Additionally, the +12V (max. 500mA) power supply for the rear-view camera can be
taken from the green wire of the 6pin to 8pin cable.

Version 23.11.2015 CI-VL2-MIB-3
Page15
2.6.2.2. Case 2: CAN-box does not detect reverse gear
If the CAN-bus interface does not deliver +12V on the green wire of the 6pin to 8pin cable
when reverse gear is engaged (not all vehicles are compatible) an external switching signal
from the reverse gear light is required. As the reverse gear light signal contains electronic
interference, a normally open relay (e.g AC-RW-1230 with wiring AC-RS5) or filter (e.g. AC-
PNF-RVC) is required. Below schema shows the use of a relay (normally open).
Cut the green cable of the 6pin to 8pin cable close to the at the black 8pin connector.
Isolate the short end of the green wire (CAN-box side).
Connect reverse gear light signal/power to coil (85) and ground to coil (86) of relais.
Connect rear-view camera power and green wire (video interface side) of 6pin to
8pin cable to output (87) of relay.
Connect permanent battery power to input (30) of relay.

2.6.2.3. Video signal connection
Connect the video-RCA of the after-market rear-view camera to the female RCA port
of the video-interface which is labeled as CAM.
Note: Picture settings for CAM input must be done in AV2.
2.7. Connecting video-interface and keypad
Connect the female 4pin connector of the keypad to the male 4pin connector of the
video-interface.
