Legal Information
By law, watching moving pictures while driving is prohibited, the driver must not be
distracted. We do not accept any liability for material damage or personal injury resulting,
directly or indirectly, from installation or operation of this product. Apart from using this
product in an unmoved vehicle, it should only be used to display fixed menus or rear-view-
camera video when the vehicle is moving (for example the MP3 menu for DVD upgrades).
Changes/updates of the vehicle’s software can cause malfunctions of the interface. Up to
one year after purchase we offer free software-updates for our interfaces. To receive a free
update, the interface has to be sent in at own cost. Wages for de-and reinstallation and
other expenditures involved with the software-updates will not be refunded.
1. Prior to installation
Read the manual prior to installation. Technical knowledge is necessary for installation. The
place of installation must be free of moisture and away from heat sources.
1.1. Delivery contents
Take down the serial number of the interface and store this manual for support
purposes: ____________________

Compatibility
Limitations
Video only The interface inserts ONLY video signals into the infotainment.
For audio inserting, use the possibly existing factory audio-AUX-input
or a FM-modulator.
Connecting 2 AV-sources If 2 AV-sources shall be connected to the infotainment the optional
audio switch SW-A2X1 is available, which is controlled by the video
interface.
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 NTSC video sources compatible only.

1.3. Connection - Video-Interface
The video-interface converts the connected after-market sources video signals into an RGB
digital signal which is inserted in the factory monitor using separate trigger options and it
reads 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 8 dip-switches of the
video-interface. Dip position down is ON and position up is OFF.

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`s 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 RGB digital 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 “V4 Reverse”while the
reverse gear is engaged.
Note: Dip 1, 4, 6, 7 and 8 are out of function and have to be set to OFF.
1.5. Settings of the 4 Dip switches (CAN function - red)
Dip position down is ON and position up is OFF.

2. Installation
Switch off the ignition and disconnect the vehicle’s battery! The interface needs a
permanent 12V source. If -according to factory rules- a disconnection of the battery has to
be avoided, it should be sufficient to use the vehicle’s sleep-mode. In case, the sleep-mode
doesn’t succeed, the battery has to be disconnected with a resistor lead.
The Interface needs a permanent power supply! If power isn’t directly taken from the
battery, the connection’s power has to be checked for being start-up proven and
permanent.
2.1. Place of installation –video-interface
The video-interface shall be installed on the backside of the head-unit.
2.2. Place of installation –daughter PCB
The daughter PCB is performed to be installed on the rear side of the head unit’s monitor
instead of the original base plate

2.4. Connection –ribbon cables
Remove the head-unit and further remove the original housing base plate on the rear side of
the monitor (4screws), to set free the 40pin ribbon cable.
Clip out the monitor’s original copper
coloured 40pin ribbon cable which is
connected at the head-unit
mainboard’s ribbon cable base and
connect it to the PCB’s outer
40pin ribbon cable merger.
Connect the daughter PCB’s pre-assembeled inner
40pin ribbon cable to the previously become free
ribbon cable base of the monitor mainboard.
Note: Heed the following warning notes
concerning installation of ribbon cables!

2.4.1. Warning notes, concerning the installation of ribbon cables:
1) The contacting ends of ribbon cables always have to be installed in a straight and
precise 180° position to the connector. Each deviation from a perfect contact position will
curse faulty contact and even danger of short circuit
2) The ribbon cable’s contacting sides always have to correspond to the contacting sides of
the connectors, concerning the mounting position.
3) Avoid cable contusion or cable injury caused by sharp-edged metal.
