Limitations
Video only The interface inserts ONLY video signals into the infotainment.
For sound use the possibly existing factory-audio-AUX-input or a
FM-modulator. If 2 AV sources shall be connected, the CAB-FV-
AUDIO audio cable is optionally available for audio switching.
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 connected after-market sources
video signals to an LVDS signal which is the inserted into the factory
monitor on certain trigger options.

1.4 Dip-switch settings
Some settings must be selected by the dip-switches on the
video-interface. Dip position down is ON and position up is OFF.
After each Dip-switch-change a power-reset of the Interface-box has to be performed!
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)
Dip 7 and 8 are 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 (both OFF, both ON, 7 OFF and 8 ON, 7 ON and 8 OFF) - 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 4 options, retry and disconnected the 6pin power plug of the video-
box between every change of the dip setting.

2. Installation
Switch off ignition and disconnect the vehicle’s battery! The interface needs a permanent
12V source. If according to factory rules disconnecting the battery is to be avoided, it is
usually sufficient to put the vehicle is sleep-mode. In case the sleep-mode does not show
success, disconnect the battery with a resistor lead.
If power source is not taken directly from the battery, the connection has to be checked
for being start-up proven and permanent.
2.1. Place of installation
The interface is installed on the backside of the vehicle’s monitor.

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 - factory monitor
Connect 10pin Microfit connector of the LVDS Switch to the 10pin Microfit
connector of the video-interface.
Disconnect the vehicle harness’ 10pin LVDS connector at the rear-side of the factory
monitor and connect it to the male 10pin connector of the LVDS switch-box.
Attention: The angle position of the factory female 10pin LVDS connector’s cable
may vary and moreover the connection isn’t non-interchangeable!
Pay attention to a correct connection of the 10 pins inside!
Connect the female 10pin LVDS connector to the previously become free 10pin LVDS
connector of the factory monitor

2.5. Connection - video sources
It is possible to connect two after-market AV sources and one after-market rear-view camera
to the video-interface
Before final installation we recommend a test run to make sure that vehicle and interface
are compatible. Due changes within the production line of the vehicle manufacturer the
risk of incompatibility always exists.
2.5.1. Video-sources to AV1 and AV2
Connect video RCA of the AV-source 1 to the female RCA connector AV 1 of the video
interface.
Connect video RCA of the AV-source 2 to the female RCA connector AV 2 of the video
interface.
