Limitations
Video only The interface inserts ONLY video signals into the infotainment.
For sound use the possibly exisng factory-audio-AUX-input or a
FM-modulator.
Factory rear-view camera Automac switch-back from inserted video to factory rear-view
camera only while reverse gear is engaged. To delay the switch-
back me, addional electronics is required.
1.2. Checking the compatibility of vehicle and accessories
1.3. Boxes and connectors
1.3.1. Video-interface
The video-interface converts the connected aer-market sources video signals to an GVIF
signal which is the inserted into the factory monitor on certain trigger opons.

1.3.2. GM-LAN box
The GM-LAN box reads digital signals from the GM-LAN-bus and converts them for the
video-interface.
1.4. Dip-switch settings
Some sengs must be selected by the dip-switches on the
video interface. Dip posion down is ON and posion up is OFF.
See following chapters for detailed informaon.
1.4.1. Enabling the interface’s video inputs (dip 1-3)
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. RGB-video input signal selection for after-market navigation (Dip 4)
If an aer-market RGB navigaon or other RGB video source is connected, the source’s RGB
output signal must match the interface’s RGB video input seng.

1.4.3. Rear-view camera setting (dip 5)
If set to OFF, the interface switches to factory GVIF picture while the reverse gear is engaged
to display factory rear-view camera or factory opcal park system picture.
If set to ON, the interface witches to its rear-view camera input CAM while the reverse gear
is engaged.
1.4.4. Monitor selection (dip 7-8)
Dip 7 and 8 are for monitor-specific video sengs which cannot be predicted as even within
the same head-unit version, the monitor specificaons may vary. It is necessary to try all
possible combinaons (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
combinaon gives the best picture quality and size (some may give no picture). It is possible
to first hot plug through the dip combinaons, but if you do not experience any change of
picture aer trying all 4 opons, retry and disconnected the 6pin power plug of the video-
box between every change of the dip seng.
2. Installation
Switch o 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 sucient 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 factory monitor.

2.5. Connecting peripheral devices
It is possible to connect 2 aer-market AV-sources, an aer-market rear-view camera and an
aer-market navigaon to the video-interface.
Before nal installation of the per ipheral devices, we recommend a test-run to detect
incompatibility of vehicle and interface. Due to changes in the production of the vehicle
manufacturer is always the possibility of incompatibility.
