In case that 2 AV sources shall be connected, a desired audio
switching will require additional electronic.

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.

Guidelines Displayed guidelines are not available in all vehicles.

1.2. Checking the compatibility of vehicle and accessories

1.3. Connectors – video interface

The video-interface converts the video signals of connected after-market sources in a factory
monitor compatible picture signal which is inserted in the factory monitor, by using separate
trigger options. Further it reads the vehicle’s digital signals out of the vehicle’s CAN-bus and
converts them for the video interface.

3. 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.

Version 01.08.2019 HW: CAM(98)/(V11+V41) RL4-SY3

Page16

3.1. 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.

3.2. 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 01.08.2019 HW: CAM(98)/(V11+V41) RL4-SY3

Page17

3.3. 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.

3.3.1. 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 01.08.2019 HW: CAM(98)/(V11+V41) RL4-SY3

Page18

3.3.2. 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 voltage­stable 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 power­cable, like you did it to the green “Reverse-IN” cable before.

Connect permanent power / 12V to the relay’s input connector (30).

Version 01.08.2019 HW: CAM(98)/(V11+V41) RL4-SY3

Page19

3.4. Connecting video-interface and 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.

Version 01.08.2019 HW: CAM(98)/(V11+V41) RL4-SY3

3.5. Picture settings

The picture settings are adjusted by the 3 buttons on the video-interface. Press the MENU
button to open the OSD settings menu. To switch to the next menu item, pressing UP and

DOWN will change the selected value. The buttons are embedded in the housing to avoid

accidental changes during or after installation. The picture settings have to be done
separately for AV1, AV2 and CAM while the corresponding input is selected and visible on
the monitor.

Note: The OSD menu is only shown when a working video source is connected to the
selected video-input of the interface.

The following settings are available

4. Interface operation

4.1. By Call-Off button

Switching the video sources can be done by a long press of the vehicle’s Call-Off button

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 …

Disabled inputs will be skipped.

Switchover by vehicle buttons isn’t possible in all vehicles. In some vehicles the external

keypad has to be used.

4.2. By keypad

Alternatively or additionally to the factory infotainment buttons, 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.

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.
