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 interface has to be connected at the factory head-unit and the factory monitor.
The factory head unit in the Insignia-B is possibly located in the passenger footwell on the
right side under the glove compartment.

2.4.1. Connection of the yellow wire in case of faulty touch function or non-off-switching
of the video interface
If, after having completely connected the video interface, the touch functions fail after
disengaging reverse gear the first time, or if the interface does not switch off after reaching
vehicle's sleep mode, the yellow wire of the PNP harness has to be disconnected on the
interface side and connected as follows:
Cut the yellow wire of the PNP harness near the 10pin connector and connect it to the
vehicle’s +12V S-Contact (terminal 86s). Insulate the other side of the yellow cable, as it is
powered!
Attention: The fuse, installed in the yellow cable, has to be connected in every case!

2.5. Analog power supply for the video interface
Exceptionally, the CAN communication may not succeed in all vehicles! If, after connecting the
PNP harness, no interface LED lightens up while the ignition is turned on, the analog power
supply needs to be done.
Connect the 12pin interface cable’s white coloured female 12pin connector to the
12pin connector of the video interface.
Connect the purple coloured wire Manual ACC of the 12pin interface cable to
+12V ACC power supply

2.7. Connection - 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 a final installation of the video sources, we recommend a test-run to ensure the
compatibility 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“.

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 (of the 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, too (if Dip 1 is
set to ON and the front camera input is selected).

Version 12.04.2023 HW: CAM(V100)/(V21+V13.3) RL4-MM-R
Page16
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 20pin
cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set video interface’s dip5 to ON before testing.
2.7.3.1. Case 1: Interface receives the reverse gear signal
If the interface delivers +12V on the green output wire of the 12pin interface cable while
reverse gear is engaged, the video interface will automatically switch to the rear-view
camera input “V4 Reverse”while the reverse gear is engaged.
Additionally, the +12V (max. 3A) power supply for the rear-view camera can be taken
from the green wire of the 12pin interface cable.

Version 12.04.2023 HW: CAM(V100)/(V21+V13.3) RL4-MM-R
Page17
2.7.3.2. Case 2: Interface does not receive the reverse gear signal
If the video interface does not deliver +12V on the green wire of the 12pin 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-
stabile 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 preconnected male- and female connectors of the 12pin
interface cable and connect the green input cable “Reverse-IN” to the output
connector (87) of the relay.
Note: Last but not lot 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 stabile and permanent +12V to the relay’s input connector (30).

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

3. Interface operation
3.1. By factory infotainment button
To switch the interface’s activated video sources, the factory infotainment buttons can be
used.
Press the according infotainment button to switch the input from the factory video to the
inserted video sources. If all inputs are activated by dip switch settings, the order is the
following:
Factory video  Video IN 1  Video IN 2  factory video
Each press will switch to the next enabled input. Inputs which are not enabled will be
skipped.
Switchover by vehicle buttons isn’t possible in all vehicles. In some vehicles the external
keypad has to be used.
