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).

2.3. Connection - 6pin interface cable
Connect the white female 6pin connector of the 6pin interface cable to the male 6pin
connector of the video interface.
Connect the green wire of the 6pin interface cable to +12V of the reverse gear signal.
(e.g. reversing light).
If desired, the white wire of the 6pin interface cable can be used alternatively to the
external button to switch the video sources (12V pulse for 2-3 seconds).
Connect the black wire of the 6pin interface cable to vehicle ground.
Connect the red wire of the 6pin interface cable to +12V ACC terminal 15.
Connect the yellow wire of the 6pin interface cable to +12V ACC (300mA).
Note: The connection of the green wire (Reverse signal) will be described in chapter “After-
market rear-view camera”. The white wire, can be used by +12V impulse to switch the
enabled video sources , same as the keypad (see chapter “video interface-operation”).

2.4. Connection –picture signal cable
Remove the grey (Depending on the head-unit, possibly also white or pink coloured!)
female 4pin HSD connector from the rearside of the factory head unit and connect it
to the aubergine colored male 4pin HSD connector of the picture signal cable.
Connect the waterblue colored female 4pin HSD connector of the picture signal cable
to the previously become free grey (Depending on the head-unit, possibly also white
or pink coloured!) male 4pin HSD connector of the factory head-unit.
Connect the waterblue colored female HSD+2 connector of the picture signal cable
to the male HSD+2 connector of the video-interface.
Note: No liability for vehicle wire colours and pin definition!
Changes by the vehicle manufacturer are possible. The given information has to be verified
by the installer.
