Limitations:

Video only The interface inserts ONLY video signals into the infotainment. For inserting

Audio signals either the possibly existing factory audio-AUX-input or a FM­modulator can be used. If 2 audio sources shall be connected to the
infotainment, an additional electronic is necessary to switch them.

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.

Guide lines Available only for vehicles with 7inch monitor, not for 10inch monitor. If the

interface does not receive the required information from the vehicle CAN-bus,
guide lines won’t be supported.

Factory OBD socket The permanent connection of an OBD dongle product, e.g. for a tank app or an

electronic driver's logbook, may result in partial failure of switching to the rear
view camera. if the switching signal is obtained from the CAN bus. In this case
an external switching signal from the reverse gear light and an ordinary open
relay or filter are required for the installation of a rear-view camera (see
chapter: "Case 2: Interface does not receive a reverse gear signal").

reverse gear and additionally 10 more seconds delay for the time of the front camera’s back-

switching after the reverse gear has been disengaged. Furthermore, the red wire’s power
supply for the front cam becomes active with manually front camera switching (short press
of the external keypad).
If set to OFF, the video interfaces’ red wire will supply permanent +12V ACC (max 3A).

Description of the power supply output: see chapter “Power supply output”.

1.4.2. Enabling the interface’s video inputs (dip 2-3)

Only the enabled video inputs can be accessed by switching through the interface’s video

sources. It is recommended to enable only the required inputs. Then the disabled inputs will
be skipped while switching through the video interfaces inputs.

Note: Dip 4 is out of function and has to be set to OFF!

1.4.3. Rear-view camera settings (dip 5)

If set to OFF, the interface switches to factory picture while the reverse gear is engaged to
display factory rear-view camera or factory optical park system picture.
If set to ON, the interface switches to its rear-view camera input while the reverse gear is
engaged.

1.4.4. Activating – front camera back-switching (dip 6)

If set to ON, the interface switches for 10 seconds from the rear-view camera to the front
camera input after having disengaged the reverse gear. In addition, a manual switch-over to
the front camera input is possible via keypad (short press) from any image mode.
(Attend to correct adjustment of the power supply output (dip1)!

1.4.5. Activating the guidelines (dip 7)

If set to ON, the guidelines will be shown on the display. If set to OFF, the guide lines won’t
be visible on the display.

Note: If there is no communication between interface and the vehicle`s CAN-bus (several
vehicles aren’t compatible), the reverse gear guide-lines can`t be shown during the vehicle’s
operation, even if they once appear after having switched the system to powerless

1.4.6. Monitor selection (Dip 8)

Dip 8 customizes the monitor-specific video settings.
If the monitor doesn’t give a satisfying picture, change the dip position while a working video
source is connected to the chosen input of the interface.
Disconnect the 10pin plug at the interface box between every change of the dip setting.

After each Dip-switch-change a power-reset of the interface box has to be performed!

2.4.6. 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.

2.4.7. 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.

2.4.8. 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
supplies +12V (max 3A) when the reverse gear is engaged and additionally
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 supplies +12V then, too (if Dip
1 is set to ON and the front camera input is selected).

Pag

e19

2.4.9. 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.

2.4.9.1. 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.

Additionally, the +12V (max. 3A) power supply for the rear-view camera can be taken
from the green wire of the 12pin interface cable.

Note: The permanent connection of an OBD dongle product, e.g. for a tank app or an
electronic driver's logbook, may result in partial failure of switching to the rear-view camera.
if the switching signal is obtained from the CAN bus. In this case, connect the rear-view
camera as described in the following chapter "Case 2".

Version 09.10.2020 HW:CAM(V98/99/100)/(V45/46) RL4-MBN6

Pag

e20

2.4.9.2. 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).

2.5. 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.

menu item. Press UP and DOWN to change the selected value. The buttons are placed inside
in the housing to avoid accidental changes during or after the installation. Picture settings
must be done separately for all video inputs 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:

Contrast

Size H/V (picture size horizontal/vertical)

Note: If there is no communication between interface and the vehicle`s CAN-bus (several
vehicles aren’t compatible), the reverse gear guide-lines can`t be shown during the vehicle’s
operation even if they once appear after having switched the system to powerless!
Generally, guide lines are only available for vehicles equipped with 7inch monitors.

3. Interface operation

 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. If all inputs are activated by dip switch
settings, the order is the following:

Factory video  Left (V1)  Right (V2)  factory video

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 with press-repeat back to factory video.
