1.3. Connection Video-Interface
The video-interface converts the connected after-market sources video signals into an LVDS
signal which is inserted in the factory monitor using separate trigger options and it reads
vehicle’s digital signals out of the vehicle’s CAN-bus and converts them for the video
interface.
1.4. Settings of the 8 Dip switches (black)
Some settings have to be selected by the 8 dip-switches of the
video-interface. Dip position down is ON and position up is OFF.

2. Installation
Switch off the ignition and disconnect the vehicle’s battery! The interface needs a
permanent 12V source. If -according to factory rules- a disconnection of the battery has to
be avoided, it should be sufficient to use the vehicle’s sleep-mode. In case, the sleep-mode
doesn’t succeed, the battery has to be disconnected with a resistor lead.
The Interface needs a permanent power supply! If power isn’t directly taken from the
battery, the connection’s power has to be checked for being start-up proven and
permanent.
2.1. Place of installation –video-interface
The video-interface is installed on the backside of the head-unit.
2.1.1. Place of installation - daugter PCB-box
The daughter PCB is performed to be installed on the rearside of the head unit. The
connection has to be done between the monitor panel and the head unit’s motherboard.

2.3. Connections to the head-unit –LVDS
Remove the head-unit and further
remove the original housing plastic frame
which is fixed to the head-unit housing by
4 Torx screws (T10).
Turn out the 8 Torx screws (T10) of the
head-unit housing. After disconnecting
the head unit’s mainboard, take both
parts together away from the head unit’s
mainboard housing and put them aside.
Turn out the Torx screw (T10) at the
middle of the head unit’s mainboard
housing and carefully put the housing
aside to set free the monitor panel with
its kopper coulored picture ribbon cable
Carefully clip out the kopper coulored 60pin ribbon cable at the monitor panel’s ribbon cable
base and lead it out.
Note: The connected ribbon cables have to be handled with care to avoid each damage of
the sensitive electrical inducters.

Version 04.07.2023 HW: 32 VL2-UCON8-AO
Page10
Turn around the monitor panel and connect the previously become free copper coulored
60pin ribbon cable to the pre-assembled 60pin ribbon cable merger „TO PNL OUT“ of the
daughter PCB box and clip it in (heed the following warning notes!).
Note: Due to the very short length of the ribbon cable, there’s only limited space for
mounting available.
Turn around the monitor again and connect the pre assembled 60pin ribbon cable
„TO PCB IN“ of the daughter PCB box to the monitor panel’s previously become free
ribbon cable base (heed the following warning notes!).
After a check of the perfect ribbon cable connection, in reverse order fold back and clip in
the monitor panel to the head unit housing, connect the head unit mainboard and fix it to
the head unit’s rearside, before screwing on the head units frame again.

Screw in the daughter PCB box at the rearside of the head-unit by using the enclosed screws
Note: If the ribbon cables might come in contact with the housing components, they have to
be isolated to avoid short circuits and cable injury.
2.3.1. Warning notes, concerning the installation of ribbon cables
1) The contacting ends of ribbon cables always have to be installed in a straight and precise
180° position to the connector. Each deviation from a perfect contact position will curse
faulty contact and even danger of short circuit
2) The ribbon cable’s contacting side always has to correspond to the contacting side of the
connector, concerning the mounting position.
3) Avoid cable contusion or cable injury caused by sharp-edged metal.

2.4. Connections to the head-unit - Quadlock
Remove the female Quadlock connector of the vehicle harness from the rear of
the head unit and connect it to the male Quadlock connector of the Quadlock
harness.
Connect the opposite female Quadlock connector of the Quadlock harness to
the male Quadlock connector of the head-unit.
Connect the femal 6pin connector of the Power /CAN cable
to the 6pin connector of the video interface.

2.5. Connecting the Video sources
It is possible to connect one After-Market RGB navigation (or another RGB source), two
After-Market AV sources and an After-Market rear view camera to the video-interface
Before the final installation, we recommend a test-run of the interface. Due to changes in
the production of the vehicle manufacturer, there’s always the possibility of
incompatibility.
2.5.1. Video-sources to Video AV1 and Video AV2
Connect the female 6pin connector of the 6pin Power / CAN cable to the video
interface’s 6pin connector.
Connect the video RCA of the AV-source 1 to the female RCA connector “AV1”of the
video interface.
Connect the video RCA of the AV-source 2 to the female RCA connector “AV2” of the
video interface.

Version 04.07.2023 HW: 32 VL2-UCON8-AO

2.5.2. 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, the audio insertion has to be done by
the factory audio AUX input or a FM-modulator to which the interface’s sound-switch output
is connected. The inserted video-signal can be activated simultaneously to each audio-mode
of the factory infotainment.
The audio switching of the connected AV sources is performed by the video interface’s audio
switch.
2.5.2.1. Audio connection of the AV sources AV1 and AV2

Version 04.07.2023 HW: 32 VL2-UCON8-AO

2.5.3. 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. Therefore, there are two different ways of installation. If the video
interface receives a signal of the reverse gear, the green wire “Reverse-OUT” of the 20pin
cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of the video-interface to ON before testing.
2.5.3.1. Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface delivers +12V on the green wire of the 20pin cable when reverse
gear is engaged, it will automatically be switched to the rear-view camera input “CAM” while
reverse gear is engaged.
The 12 V power supply for the rear-view camera (max 3A) has to be taken from the
green wire of the 20pin cable to avoid an unnecessary permanent power supply to
the camera electronic.

Version 04.07.2023 HW: 32 VL2-UCON8-AO
Page16
2.5.3.2. Case 2: Interface does not receive any reverse gear signal
If the video interface does not deliver +12V on the green wire of the 20pin 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’s power supply isn’t voltage-
stable all the time, an ordinary open relay (e.g. AC-RW-1230 with wiring AC-RS5) or filter
(e.g. AC-PNF-RVC) is required. The diagram below shows the connection type of the relay.
Cut through the 6pin Power / CAN cable’s green cable and connect the one side
which is near to the 6pin Power /CAN connector to the output connector (87) of the
relay.
Note: Not least to avoid short circuits, the best solution should be, to crimp a male
4mm connector to the relay’s output cable and connect it to a green cable’s crimped
female 4mm connector. The remaining opposite part of the green cable remains
disconnected and should be isolated.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
Additionally connect the output connector (87) of the relay to the rear-view camera’s
power-cable, like you did it to the green “Reverse-IN” cable before.
Connect permanent power / 12V to the relay’s input connector (30).

2.5.3.3. Video signal connection for the rear-view camera
Connect the video-RCA of the after-market rear-view camera to the female RCA port
“CAM”of the video-interface.
2.6. Connecting video-interface and external keypad
Connect the external 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.

2.7. Picture settings and guide lines
The picture settings are adjusted by the 3 buttons on the video-interface. Press the MENU
button to open the OSD settings menu. To switch to the next menu item, pressing UP and
DOWN will change the selected value. The buttons are embedded in the housing to avoid
accidental changes during or after installation. The picture settings have to be done
separately for RGB, AV1 and AV2 while the corresponding input is selected and visible on the
monitor.
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
Note: The brightness setting must be
done in the Video-IN 2 input!
Saturation
Position H (horizontal)
Position V (vertical)
IR-AV1 out of function

3. Interface operation
3.1. By volume key button
A press of the volume button on the right rear side of the steering wheel switches the input
from factory mode to the inserted video sources. If -by dip switch setting- all inputs are
enabled, the order will be the following:
Factory video  RGB-in  video IN1  video IN2  factory video  …
By dip switch deactivated inputs will be skipped. The audio signal will be also be switched
automatically by the interface’s integrated audio switch when switching from AV1 to AV2
Switchover by vehicle buttons isn’t possible in all vehicles. In some vehicles the external
keypad has to be used.
3.2. By external keypad
Alternatively or additionally to the steering wheel’s volume button, the interface’s enabled
inputs are also switchable by the external keypad.
