1.3. Boxes and connectors
1.3.1. 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.
1.3.2. CAN-bus box
The CAN box 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 –interface
Some settings have to be selected by the dip-switches on
the video interface.
Dip position down is ON and position up is OFF.
After each Dip-switch-change a power-reset of the Can-box has to be performed!
See the following chapters for detailed information.
1.4.1. Enabling the interface’s video inputs (dip 2-3)
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, because the disabled inputs
will be skipped while switching through the video interfaces inputs.
1.4.2. 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 switches to its rear-view camera input while the reverse gear is
engaged.
1.4.3. Monitor selection (dips 6-8)
Dips 6-8 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 - 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 options, retry and disconnected the 6pin
power plug of the video-box between every change of the dip setting.
Note: Dip 1 and 4 are out of function and have to be set to OFF.

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 –video interface and CAN box
The interface is built to be connected at the factory navigation blackbox.
The Built-in Locations of the factory navigation blackbox may vary, even in one and the same
vehicle’s series! Please ask for the manufacturer’s information to avoid removing the wrong
parts.
The Opel Mokka X blackbox is usually to be found behind the infotainment and
navigation monitor.
The Opel Insignia A blackbox is usually to be found behind the climate control under
the monitor.
The Opel Astra K blackbox should be found directly behind the instruments, like
shown below.
The Corvette HMI module is located in the driver’s footwell in front of the A-pillar.
Other Built-in locations of the blackbox like in in the passenger’s foot well in front of the A-
pillar or even behind or near the glove box are possible.
Example: location of the Opel Astra K factory blackbox

2.6. Connection - Video-sources
It is possible to connect two after-market video 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.
Connect the video cable’s female 6pin connector to the video interface’s male 6pin
connector.
Connect the RCA of the video source 1 and video source 2 to the female RCA „Video
IN1“and „Video IN2“of the video cable.

2.7. Audio-switch and audio-insertion
This interface is only able to 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 simultaneously to each audio-mode of the factory
infotainment.

Note: If only one AV-source shall be connected, it is possible to connect the audio output of
the AV-source directly to the point of audio-insertion (e.g. audio AUX input).
Connect the audio cable’s female 7pin connector to the male 7pin connector of the
video-interface.
Connect the audio-RCA of the possibly existing factory AUX-input or the FM-
modulator to the audio cable’s female RCA port “Audio OUT”.
Connect the audio-RCA of AV-source 1 and AV source 2 to the female RCA port of the
audio cable’s „Audio 1 IN“ und „Audio 2 IN“.

Version 23.02.2021 HW: 25(V92)/(V51) CI-VL2-N902

2.8. 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. In this case there are two different ways of installation. If the
CAN-box is able to detect an enabled vehicle’s reverse gear, the green wire of the 6pin to
12pin cable carries +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before testing.
2.8.1. 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
„CAMERA IN“ 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 6pin to 12pin cable.

Version 23.02.2021 HW: 25(V92)/(V51) CI-VL2-N902
Page15
2.8.2. . Case 2: CAN-box does not receive the reverse gear signal
If the CAN-bus interface does not receive +12V on the green wire of the 6pin to 12pin 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 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).
Cut the green cable of the 6pin to 12pin cable close to the black 12pin connector and
isolate the shorter end of the green cable near to the 12pin connector (CAN-box
side).
Connect the reverse gear light signal/power to coil terminal (85) and vehicle’s ground
to coil terminal (86) of relay.
Connect the rear-view camera power wire and the green wire (video interface side)
of the 6pin to 12pin cable both to output terminal (87) of the relay.
Connect permanent battery power to input terminal (30) of relay.
Note: If, due to a missing CAN communication, the 6pin to 12pin cable has been connected
the analogue way instead of the Can box, the green wire’s connection has also to be done as
shown in the picture above.

2.9. Connection - video-interface and external keypad
Connect the keypad’s female 4pin connector to the video-interface’s male 4pin
connector.
Note: Even if the switching through several video sources by the keypad mightn’t be
required, the invisible connection and availability is strongly recommended.

Version 23.02.2021 HW: 25(V92)/(V51) CI-VL2-N902

2.10. Picture settings and guide lines
The picture settings are adjustable by the 3 push-buttons on the video-interface. Press the
MENU button to open the OSD settings menu or to switch to the next menu item. Press UP
and DOWN to change the selected value. The buttons are placed inside in the housing to
avoid accidental changes during or after the installation. Picture settings must be done
separately for AV1 and AV2 while the corresponding input is selected and visible on the
monitor. AV2 and CAM share the same settings which must be adjusted in AV2.
Note: The OSD menu is only shown when a working video source is connected to the
selected video-input of the interface.
The following settings are available:
Contrast
Brightness
Saturation
Position H (horizontal)
Position V (vertical)
IR-AV1/2 (no function)
Guide L/R Offset adjustments
UI-CNTRL (guide lines ON/OFF)
Size H/V (picture size horizontal/vertical)
Note: If there is no communication between the CAN box and the vehicle`s CAN-bus
(several vehicles aren’t compatible), the reverse gear guide-lines can`t be shown during the
vehicle’s operation, even if they once appear after having switched the system to powerless!

3. Interface operation
3.1. By infotainment buttons
To switch the video sources the vehicle’s HOME button at the steering wheel button can be
used.
A double press of the steering wheels “Home” key switches to the next activated video
input.
If all inputs are enabled the order is:
Factory video  video IN1  video IN2  factory video  …
Disabled inputs will be skipped. While switching from Video IN1 to Video IN2 the audio-
source will be switched too, assuming the sources have also been connected to the audio
cable.
Switchover by vehicle buttons isn’t possible in all vehicles. In some vehicles the external
keypad has to be used (see following chapter).
3.2. By external keypad
Alternatively or additionally to the factory infotainment buttons, the interface’s external
keypad can be used to switch the enabled inputs.
