Limitations
Video only The interface inserts ONLY video into the infotainment.
For sound use the possibly existing factory-audio-AUX-input, a
FM-modulator or the AUX-in interface AUX-110.
Factory OPS Display of an optical park display (OPS) isn’t possible if an
after-market rear-view camera is connected and reverse gear is
engaged. Acoustic signals are still existing.
Factory rear-view camera Automatic switch-back from inserted video to factory rear-view
camera only while reverse gear is engaged. To delay the switch-
back time, additional electronics is required.
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.

1.4. Dip-switch settings - video interface
Some settings must be selected by the dip-switches on the
video interface. Dip position down is ON and position up is OFF.
See following chapters for detailed information.
1.4.1. Enabling the interface’s video inputs (dip 2-3)
Only the enabled video inputs can be accessed when switching through the interface’s video
sources. It is recommended to enable only the required inputs for the disabled will be
skipped when switching through the video interfaces inputs.
1.4.2. Rear-view camera setting (dip 5)
If set to OFF, the interface switches to factory LVDS 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 witches to its rear-view camera input CAM while the reverse gear
is engaged.
1.4.3. Monitor selection (dip 7-8)
Dips 7 and 8 customize the monitor-specific video settings which sometimes even vary
within head units of the same version, caused by different monitor specifications. It is
necessary to try all possible combinations of the 3 dips while a working video source is
connected to the chosen input of the interface. One of the 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 visible change of picture after trying all options, retry and
disconnect the 6pin plug of the video interface between every change of the dip setting.
Dip 1, 4 and 6 are out of function and have to be set to OFF.
After each Dip-switch-change a power-reset of the Video Interface 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!
2.1. Place of installation
The interface shell be installed on the backside of the head-unit
(navigation computer/radio).

2.5.1. After-market rear-view camera
Note: Do not forget to set dip5 of video-interface to ON before testing.
To switch to the rear-view camera when reverse gear is engaged, an external switching
signal from the reverse gear light is required. As the reverse gear light signal contains
electronic interference, a traditional open relay (e.g AC-RW-1230 with wiring AC-RS5) or
filter (e.g. AC-PNF-RVC) is required. Below schema shows the use of a relay (normally open).
Connect the green switching input cable to the output connector (87) of the relay.
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 switching input cable before.
Connect stabile and permanent +12V to the relay’s input connector (30).

2.6. Audio insertion
This interface can only insert video signals into the factory infotainment. Audio
insertion must be done by factory audio AUX input, the optionally available AUX-in
interface AUX-110 (only for MMI3G, not for MMI3G+) or 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.
2.7. Connecting - external keypad
Connect the female 4pin connector of the keypad to the male 4pin connector of the
video-interface.

2.8. 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 or to switch to the next menu item. Press UP and
DOWN will change the selected value. The buttons are embedded in the housing to avoid
accidental changes during or after installation. Picture settings must be done separately for
AV1 and AV2 while the corresponding input is selected and visible on the monitor. The rear-
view camera settings conceivably have to be done in AV 2.
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
Brightness
Saturation
Position H (horizontal picture position)
Position V (vertical picture position)
Note: To adjust the reverse picture, engage the reverse gear.

3. Switching video sources
Press theinterface’s external keypad to switch the video source. Each repetition 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.
Alternatively the white wire of the 6pin cable can be used with a +5-12V pulse to switch the
video-sources.
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.
