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 shall be installed on the backside of the head-unit.
2.2. Place of installation –daughter PCB
The daughter PCB is performed to be installed on the rear side of the head unit’s monitor
instead of the original base plate

2.4. Connections to the head-unit –ribbon cables
Remove the head-unit and further remove the original housing base plate on the rear side of
the monitor (4screws), to set free the 40pin ribbon cable.
Clip out the monitor’s original copper
coloured 40pin ribbon cable which is
connected at the head-unit
mainboard’s ribbon cable base and
connect it to the PCB’s outer
40pin ribbon cable merger.
Connect the daughter PCB’s pre-assembeled inner
40pin ribbon cable to the previously become free
ribbon cable base of the monitor mainboard.
Note: Heed the following warning notes
concerning installation of ribbon cables!

Version 19.01.2018 HW: CAM(V97)GO CI-RL3-A15
Page10
2.4.1. 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 sides always have to correspond to the contacting sides of
the connectors, concerning the mounting position.
3) Avoid cable contusion or cable injury caused by sharp-edged metal.

2.5. 20pin RGB digital cable –connection and wiring
Connect the male beige-coloured
20pin connector of the 20pin RGB
digital cable to the female 20pin
connector of the daughter PCB.
Pay special attention to the cable’s
direction because its connectors
both seem to be identical. (Strictly
respect the lables „MONITOR SIDE“
and „BOX SIDE“).
Position the daughter PCB at the
monitor’s rear-side and carefully
fold in the installed 40pin ribbon
cables into the monitor’s housing,
after leading out the grey coloured
40pin RGB digital cable at a suitable
place.
Fix the daughter PCB to the
monitor’s housing by using both
original screws.

2.6. Connection to the head-unit and Power connection
Connect the 20pin RGB digital cable’s female 20pin connector to the male 20pin
connector of the video-interface.
Connect the female 12pin connector of the 12pin interface cable to the 12pin
connector of the video interface and the 10pin connector beside to the female 10pin
connector of the 10pin power cable.
Connect the yellow and the red wire of the 10pin power cable both to +12V ACC
(Accessory power) or +12V S-contact terminal 86s (e.g. glove compartment
illumination).
Connect the single black wire of the 10pin power cable to vehicle’s negative ground.

Version 19.01.2018 HW: CAM(V97)GO CI-RL3-A15

2.7. Connecting the video sources
It is possible to connect two after-market AV-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 interface’s male
12pin connector.
Connect the video RCAs of the AV-source 1 and AV source 2 to the female RCA
connectors “Video IN1”and “Video IN2” of the 12pin interface cable.
“
Connect the video RCA of the rearview camera to the female RCA connector “Camera
IN” of the video cable.

2.7.1. After-market rear-view camera
Note: Do not forget to set dip5 of the video-interface to ON before testing.
To automatically switch to the rear-view camera input while the reverse gear is engaged, 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 terminal (85) and the vehicle’s ground
to coil terminal (86) of the relay.
Connect the output terminal (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 terminal (30).

2.8. Connecting video-interface and keypad
Connect the 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.
