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.

1.4.2. 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. So the disabled inputs will be
skipped while switching through the video interfaces inputs.
Note: Dip 4 is out of function and have to be set to OFF!
1.4.3. Rear-view camera setting (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 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!
1.4.5. Monitor type (dip 7)
Dips 7 is for monitor-specific video settings which cannot be predicted as even within the
same head-unit version, the monitor specifications may vary. It is necessary to try all
possible combinations - while a working video source is connected to the chosen input of the
interface - to see which combination gives the best picture quality and size (some may give
no picture). It is possible to first hot plug through the dip combinations, but if you do not
experience any change of picture after trying all options, retry and disconnected the 10pin
power plug of the video-box between every change of the dip setting.
1.4.6. Activation of the PDC Graphic (dip 8)
If set to ON, the PDC graphic is displayed as „picture in picture“ in combination with the
camera image.
Note: If the video interface does not receive the required information from the vehicle CAN-
bus, the optical PDC display cannot be supported.
After each Dip-switch-change a power-reset of the Interface-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.
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 installation
The interface is supposed to be installed at a suitable location behind the vehicle`s head-
unit.
*Note: In the e-tron, the following hidden screw (Torx) must be loosened at the rear of the
centre console (one screw, the rest is inserted - ventilation doesn‘t have to be removed).
2.2. Note for test run
In vehicles in which the climate control system is operated by the touchscreen monitor, it is
necessary to have the monitor connected for an interface test run.

2.6. 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 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“.
Connect the video RCA of the AV source 1 and 2 to the 12pin interface cable’s female RCA
connector “Left (V1)” and ”Right (V2)”.

Page18
2.6.1. 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.
2.6.2. 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 13.02.2023 HW: CAM(V100)/256(V22) +GW2A(V25)+GW2A(V30) RL4-MIB88
Page19
2.6.3. 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.
2.6.3.1. 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.
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 13.02.2023 HW: CAM(V100)/256(V22) +GW2A(V25)+GW2A(V30) RL4-MIB88
Page20
2.6.3.2. 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).
