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.

2.7.1. Audio-insertion
This interface is only able to insert video signals into the factory infotainment. If an AVsource 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 audiomode 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 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
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.

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 “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 28.02.2023 HW:CAM (V100)/(V23) RL4-SC15
Page 16
Pag
e16
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 voltagestabile 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.

3.2. By keypad
Alternatively or additionally to the factory infotainment buttons, the interface’s external
keypad can be used to switch the enabled inputs. Even if not needed, the keypad should
always remain connected to the video interface for support purposes.
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 long press will switch to the next
enabled input. Inputs which are not enabled will be skipped.
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 witches from the factory video to
the front camera input and back to factory video.
