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 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 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.

2.5. 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.
2.5.1. After-Market RGB navigation
Connect the female 8pin connector of the RGB cable to the male 8pin connector of
the video-interface. The loose grey wires don’t have any function and have to be
isolated.
Connect the male 6pin connector of the RGB cable to the after-Market navigation.
If the aftermarket navigation NAV-FN900E will be connected, the factory touch-screen
can be used. Please add the following step:
Connect the female 8pin connector of 6pin to 12pin cable to male 8pin connector

2.5.3. 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.

2.5.4. 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 should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before testing.
2.5.4.1. 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 6pin to 12pin cable.

Version 14.06.2017 VL2-N902
Page15
2.5.4.2. 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 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.
Isolate the short end of the green wire (CAN-box side).
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 wire (video interface side)
of 6pin to 12pin cable both to output (87) of the relay.
Connect permanent battery power to input (30) of relay.

2.5.4.3. 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: The picture settings for CAM input have to be adjusted in AV2.
2.6. Connecting video-interface and keypad
Connect the female 4pin connector of the keypad to the male 4pin connector of the
video-interface.

2.7. 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 RGB, 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
