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 FM-
modulator 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.
Video input signal Only NTSC compatible.
Guide lines If the interface does not receive the required information from the vehicle CAN-
bus, the guide-lines will not be supported.
1.2. Checking the compatibility of vehicle and accessories

Version 11.09.2019 HW:CAM (V98) / (V20) RL3-C3D
Page5
1.3. Boxes and 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.
1.4. Settings of the 8 Dip switches (black)
Some settings have to be selected by the dip-switches of the
video interface.
Dip position down is ON and position up is OFF.
In case of a non-optimal displayed picture with the mentioned dip settings of dip7 and dip8,
we recommend to try each other possible dip switch combination.
See the following chapters for detailed information.
After each Dip-switch-change a power-reset of the Can-box has to be performed!

1.4.1. Enabling the interface’s video inputs (dip 2-3)
Only by dip switches enabled video inputs can be accessed by switching through the
interface’s video sources. It is recommended to enable only the required inputs. Disabled
inputs will be skipped while switching through the video interfaces inputs.
Note: Dip 1 and 4 are out of function and have to be set to OFF!
1.4.2. Rear-view camera setting (dip5)
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.
1.4.3. Activating the guide lines (dip6)
If set to ON, the guide-lines 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!
1.4.4. Monitor selection (dip7 and 8)
Dips 7-8 customize the monitor-specific video settings. For the according monitor, use the
dipswitch combinations shown in the table below. Sometimes the mentioned settings vary
even within head units of the same version, caused by different monitor specifications. In
case of a non-optimal displayed picture with the mentioned dip settings, we recommend to
try each other possible dip switch combination of dip7 and dip8 while a working video
source is connected to the chosen input of the interface. One of the 4 combinations will
show the best picture size and quality (some may give no picture). It is possible to first hot
plug through the dip combinations. If there is no change of picture visible after trying all 4
options, retry and disconnect the 6pin plug at the interface box between every change of the
dip setting.

setting of dip-1 has to be changed to „OFF“.
After each Dip-switch-change a power-reset of the Can-box has to be performed!
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.
If the necessary stabilized power supply for the interface is not taken directly from the
battery, the chosen connection has to be checked for being constantly stabile.
The interface needs a permanent 12V source!
Before a final installation, we recommend a test-run to ensure the compatibility of the
vehicle and the interface. Due to changes in the production of the vehicle manufacturer
there’s always a possibility of incompatibility.
2.1. Place of installation
The interface is supposed to be installed at a suitable location behind the vehicle`s head-
unit.

2.4. Connecting video sources
It is possible to connect an after-market rear-view 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 female 12pin connector of the 12pin interface cable to the male 12pin
connector of the video-interface.
Connect the video RCA of the video source 1 and 2 to the female RCA connector “Video IN1”
and ”Video IN 2” of the 12pin interface cable.
Connect the video RCA of the rear-view camera to the female RCA connector “Camera IN” of
the 12pin interface cable.

Version 11.09.2019 HW:CAM (V98) / (V20) RL3-C3D

2.4.1. 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.
2.4.2. 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.
2.4.2.1. 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.

Version 11.09.2019 HW:CAM (V98) / (V20) RL3-C3D
Page13
2.4.2.2. Case 2: CAN-box 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).

2.5. Connecting 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.

2.6. Picture settings and guide lines
The picture settings are adjustable by the 3 push-buttons at the rear-side of the video-
interface. Press the MENU button to open the OSD settings menu or to switch to the next
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 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:
Contrast

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.
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.
