For audio inserting, use the possibly existing factory audio-AUX-input
or a FM-modulator. If 2 AV-sources shall be connected to the
infotainment, for audio switching an additional electronic part is
required.
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.

1.3. Connection - Video-Interface
The video-interface converts the connected after-market sources video signals into an RGB
digital 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 at the
video-interface. Dip position down is ON and position up is OFF.
See the following chapters for detailed information.
After each Dip-switch-change a power-reset of the Can-box has to be performed!

1.4.1. 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”.
1.4.2. 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.
1.4.3. 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.
1.4.4. Monitor selection (dip 7 and 8)
Dips 7-8 customize the 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: Dips 4 und 6 are out of function and have to be set to 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.
Before a final installation, we recommend a test-run to ensure the compatibility of the
vehicle and the interface. Due to changes in the production of the vehicle manufacturer
there’s always a possibility of incompatibility.
2.1. Place of installation
2.1.1. Place of installation –video-interface
The video-interface has to be installed on the backside of the head-unit.
2.1.2. Place of installation - daugter PCB
The daughter PCB has to be installed inside 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.
3) Avoid cable contusion or cable injury caused by sharp-edged metal.

2.7. Connecting the Video sources
It is possible to connect two after-market Video-sources and one 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.
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“.

2.7.1. 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 2 AV sources shall be connected to the infotainment,
additional electronic is necessary to switch the audio signals.
2.7.2. 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 23.11.2020 HW: CAM(V98/(V12) CI-RL4-UCON8-LV
Page17
2.7.3. 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 12pin
cable should carry +12V while the reverse gear is engaged. See the following illustration for
the according connection.
Note: Do not forget to set dip5 of the video-interface to ON before testing.
2.7.3.1. 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 “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 stay
connected.

Version 23.11.2020 HW: CAM(V98/(V12) CI-RL4-UCON8-LV
Page18
2.7.3.2. 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.
Disconnect the green cable’s pre-connected male- and female connectors of the
12pin 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).

Page19
2.8. Connection - external keypad
Connect the keypad’s female 4pin connector to the 12pin interface cable’s male 4pin
connector.
Note: Even if the switching through several video sources by the keypad mightn’t be
required, the keypad’s invisible connection and availability is strongly recommended.

3. Interface operation
The interface’s external keypad can be used to switch the enabled inputs.
Long press of keypad (2-3 seconds)
By long pressing the external keypad (2-3 seconds), the video interfaces witches the input
from the factory video to the inserted video sources.
Each press (approx. 2 sec) will switch to the next enabled input. If all inputs are enabled the
order is:
Factory video  video IN1  video IN2  factory video  …
By dip switch deactivated inputs will be skipped. If an audio switch has been connected in
the system, also the audio signal will be switched when switching from video IN1 to video
IN2
Note: The interface switches after releasing the switch (after long pressure).
Short press of keypad (only if DIP 1 is set to ON)
By short pressing the external keypad, the video interfaces switches from the factory video
to the front camera input and back to factory video.
