Limitations
Video only The interface inserts ONLY video signals into the infotainment.
For inserting Audio signals either the possibly existing factory audio-AUX-input
or a FM-modulator can be used.
In case that 2 AV sources shall be connected, a desired audio switching will
require additional electronic.
Factory rear-view camera Automatically switching-back from inserted video to factory rear-view camera is
only possible while the reverse gear is engaged. To delay the switch-back an
additional electronic part is required.
After market front camera The front camera will automatically be switched for 10 seconds after
disengaging the reverse gear. A manually front camera switching is possible by
external keypad.
Video input signal NTSC video sources compatible only.
1.2. Checking the compatibility of vehicle and accessories
1.3. Connectors
1.3.1. Connectors - 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.

1.4.1.1. Activating the front camera input (dip 1)
If set to ON, the interface switches for 10 seconds from the rear-view camera to the front
camera input after having disengaged the reverse gear. In addition, a manual switch-over to
the front camera input is possible via keypad (short press) from any image mode.
Description of the power supply output: see chapter “Power supply output”.
1.4.1.2. Enabling the interface’s video inputs (dip 2-3)
Only the enabled video inputs can be accessed when switching through the interface’s video
sources. It is recommended to enable only the required inputs, disabled inputs
will be skipped when switching through the video-interfaces inputs.
1.4.1.3. Rear-view camera setting (dip 5)
If set to OFF, the interface switches to factory picture while the reverse gear is engaged to
display factory rear-view camera.
If set to ON, the interface switches to its rear-view camera input „Camera-IN“ while the
reverse gear is engaged.
1.4.1.4. Monitor setting (Dip 6, 7 und 8)
Dip6 and dip8 must be set to OFF.
Dip7 must be set to ON
Note: In case of a non-optimal displayed picture with the mentioned dip settings of dip6, 7
and 8, we recommend to try all other dip switch combinations.
Note: Dip4 is out of function and have to be set to OFF.
After each Dip-switch-change a power-reset of the Video Interface has to be performed!

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.
As with any installation of retrofit equipment, a stand-by test is neccessary after the
installation of the video interface, to ensure that the unit also switches off after reaching
the vehicle‘s sleep mode.
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.
2.1. Place of connection
The daughter PCB has to be installed and connected inside the factory head unit behind the
monitor panel.
The video Interface has to be connected at the daughter PCB inside and at the rear-side of
the head-unit.

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.

2.9. Connecting Video sources
It is possible to connect an after-market rear-view camera, an after-market front camera and
two more video sources to the video-interface.
Before the final installation, 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 12pin interface cable’s female 12pin connector to the male 12pin connector of
the video-interface.
Connect the video RCA of the Rear-view camera to the 12pin interface cable’s female
RCA connector „Reverse V4.
Connect the front camera’s video RCA connector to the 12pin interface cable’s female
RCA connector „Front V3“.
Connect the video RCA of the AV source 1 and 2 to the 12pin interface cable’s female RCA
connector “Left (V1)” and ”Right (V2)”.

2.9.1. Audio-insertion
This interface is only able to insert video signals into the factory infotainment. If an AV-
source is connected, the audio insertion has to be done by the factory audio AUX input or an
FM-modulator. The inserted video-signal can be activated simultaneously to each audio-
mode of the factory infotainment. If two AV sources shall be connected to the infotainment,
additional electronic is necessary to switch the audio signals.
2.9.2. After-market front camera
The red power supply output ACC/front cam out 12V (max 3A) can be used to power
a front camera. If Dip 1 is set to ON (black 8 dips), the power supply output gives
+12V (max 3A) when reverse gear is engaged incl. 10 seconds delay after reverse gear
is disengaged.
Note: In addition, a manual switch-over to the front camera input is possible via keypad
(short press) from any image mode. The power supply output gives +12V then, as well (if Dip
1 is set to ON and the front camera input is selected).
Attention: A long press of the external keypad push button will switch the interface to the
next source.

Version 14.03.2023 HW CAN(V100)/GW2A(V20) RL4-UCON8-20
Page19
2.9.3. 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.
2.9.3.1. Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface receives +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 “Camera IN”
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.
For the operation, both green cables “Reverse IN” and “Reverse OUT” have to remain
onnected.

Version 14.03.2023 HW CAN(V100)/GW2A(V20) RL4-UCON8-20
Page20
2.9.3.2. ACase 2: Video interface does not receive the reverse gear signal
If the video interface does not receive +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.
Disconnect the green cable’s pre-connected male- and female connectors of the
20pin cable and connect the green input cable “Reverse-IN” 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 the green cable’s female
4mm connector. The output-cable “Reverse-OUT” remains disconnected as it’s out of
function.
Connect the Reverse light’s power-cable to coil (85) and the vehicle’s ground to coil
(86) of the relay.
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).
