1.4.1.1. Enabling the interface’s video inputs (dip 1-3)
Only the enabled video inputs can be accessed by switching through the interface’s video
sources. It is recommended to enable only the required inputs. So the disabled inputs will be
skipped while switching through the video interfaces inputs.
1.4.1.2. Vehicle specific settings (Dip 4)
Set Dip switch 4 to ON for Audi TT vehicles. For all other vehicles it has to be set to OFF.
1.4.1.3. 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 switches to its rear-view camera input while the reverse gear is
engaged.
1.4.1.4. Monitor selection (Dip 6-8)
Dips 6-8 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. One of the six combinations will show the best picture size and quality
(some may give no picture). It is possible to first hot plug through the dip combinations. If
there is no change of picture visible after trying all 6 options, retry and disconnect the 10pin
plug of the Quadlock connector between every change of the dip setting.

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 is built to be connected behind the vehicle`s head-unit.

2.4. Connecting peripheral devices
It is possible to connect one after-market RGB navigation (or another RGB video source), two
after-market AV-sources and one after-market rear-view camera to the video-interface.
Before final installation of the peripheral devices, we recommend a test-run to detect a
incompatibility of vehicle and interface. Due to changes in the production of the vehicle
manufacturer there’s always a possibility of incompatibility.
2.4.1. Video-sources to Video IN1 and Video IN2
Connect the female 20pin connector of the connection cable to the male 20pin
connector of the video-interface.
Connect the video RCA of the AV-source 1 to the female RCA connector Video IN1 of
the 20pin connection cable.
Connect the video RCA of the AV-source 2 to the female RCA connector Video 2 of
the 20pin connection cable.

Version 21.06.2017 CI-VL3-MIB-4
Page11
2.4.2. Audio-insertion
This interface is only able to insert video signals into the factory infotainment. If an AV-
source is connected, audio insertion must be done by factory audio AUX input or FM-
modulator. The inserted video-signal can be activated simultaneously to each audio-mode of
the factory infotainment.
2.4.2.1. Connection of 2 Audio sources
If two AV-sources shall be connected, the optionally available audio switch SW-A2X1 is
needed. When switching the video interface from video-IN1 to video-IN2, the audio will also
automatically be switched by the SW-A2X1.
Connect the pink cable (Audio switch - power) of the 20pin connection cable to BATT
of the external Audio switch SW-A2X1.
Connect the black cable (Audio switch - ground) oft he 20pin connection cable tot he
grey cable of the external Audio switch SW-A2X1.

Version 21.06.2017 CI-VL3-MIB-4
Page12
2.4.3. After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the video-interface
is not compatible with. In this case there are two different ways of installation. If the video-
interface is able to detect an enabled vehicle’s reverse gear, the green wire of the 6pin to
12pin cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before testing.
2.4.3.1. Case 1: CAN-box receives the reverse gear signal
If the CAN-bus box delivers +12V on the green wire of the 6pin to 12pin cable while reverse
gear is engaged, the video interface will automatically switch to the rear-view camera input
CAM while the 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 20pin connection cable.

Version 21.06.2017 CI-VL3-MIB-4
Page13
2.4.3.2. Case 2: CAN-box does not receive the reverse gear signal
If the CAN-bus interface does not deliver +12V on the green wire of the 20pin connection
cable when reverse gear is engaged (not all vehicles are compatible) an external switching
signal from the reverse light is required. As the reverse gear light signal contains electronic
interference, a traditional 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).
Disconnect the green rear-view camera input cable of the 20pin connection cable
from the rear-view camera output cable near the transparent plug.
The green rear-view camera output cable of the 20pin connection cable is not used.
Connect the reverse gear light signal/power to coil (85) and ground to coil (86) of
relay.
Connect the rear-view camera power wire and the green rear-view camera input
cable of the 20pin connection cable both to output (87) of the relay.
Connect permanent battery power to input (30) of relay.

Version 21.06.2017 CI-VL3-MIB-4

2.4.3.3. Video signal connection of rear-view camera
Connect the video-RCA of the after-market rear-view camera to the female RCA port
of the 20pin connection cable which is labeled as CAM.
2.5. Connecting video-interface and keypad
Connect the female 4pin connector of the keypad to the male 4pin connector of the
20pin connection cable.
