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
The video interface is designated to be connected behind the vehicle`s head unit.
The daughter PCB shell be installed and connected inside the factory head unit behind the
monitor panel.

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.
2.4. Connection –picture signal cable
Connect the opposite female 20pin connector of the pre-connected 20pin picture signal
cable to the male 20pin connector of the video interface.

2.8. 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)”.

2.8.1. 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.
2.8.2. 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 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP
Page18
2.8.3. After-market rear-view camera:
Some vehicles have a different reverse gear code on the CAN-bus which doesn’t
communicate with the interface’s CAN. In this case there are two different ways of
installation. If the interface’s CAN 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.
2.8.3.1. Case 1: Interface receives the reverse gear signal
If the interface receives +12V on the green wire of the 12pin interface 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.
The 12 V power supply for the rear-view camera (max 3A) has to be taken from the
12pin interface cabl’s green wire “Reverse-OUT” to avoid an unnecessary,
permanent power supply to the camera electronic.
Both green cables “Reverse IN” and “Reverse OUT” have to remain connected.

Version 24.09.2019 HW CANM(V98)/(V34) RL4-UCON8-CP
Page19
2.8.3.2. Case 2: Interface does not receive the reverse gear signal
If the video interface does not receive +12V on the green wire of the 12pin interface 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).

2.9. 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.
