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.

2.5.3. Audio-switch and audio insertion
This interface can only insert video signals into the factory infotainment and switch audio
signals. If an AV-source is connected to AV1 or AV2, audio inseron must be done by factory
audio AUX input or FM-modulator to which the interface’s sound-switch output is
connected. When the interface is switched from AV1 to AV2, the audio signal is switched
parallel to the corresponding video signal by the interface’s built-in audio-switch.
The inserted video-signal can be acvated simoultaneously to each audio-mode of the
factory infotainment.

2.5.4. After-market rear -view camera
Some vehicles have a different reverse gear code on the GM-LAN which the included GM-
LAN box is not compable with. Therefore there is two different ways of installaon. If the
GM-LAN box can detect the reverse gear in the vehicle, the green wire of the 6pin to 8pin
cable should carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before tesng.
2.5.4.1. Case 1: GM -LAN box detects reverse gear
If the CAN-bus interface delivers +12V on the green wire of the 6pin to 8pin cable when
reverse gear is engaged, the video interface will automacally be switched to the rear-view
camera input CAM while reverse gear is engaged.
Addionally, the +12V (max. 500mA) power supply for the rear-view camera can be
taken from the green wire of the 6pin to 8pin cable.

Version 02.10.2015 NA-VL2DVD900
Page14
2.5.4.2. Case 2: GM -LAN box does not detect reverse gear
If the GM-LAN box does not deliver +12V on the green wire of the 6pin to 8pin cable when
reverse gear is engaged (not all vehicles are compable) an external switching signal from
the reverse gear light is required. As the reverse gear light signal contains electronic
interference, a normally 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).
Cut the green cable of the 6pin to 8pin cable close to the at the black 8pin connector.
Isolate the short end of the green wire (GM-LAN box side).
Connect reverse gear light signal/power to coil (85) and ground to coil (86) of relais.
Connect rear-view camera power and green wire (video interface side) of 6pin to
8pin cable to output (87) of relay.
Connect permanent baery power to input (30) of relay.

2.5.4.3. Video signal connection
Connect the video-RCA of the aer-market rear-view camera to the female RCA port
of the video-interface which is labeled as CAM.
Note: Picture sengs for CAM input must be done in AV2.
2.6. Connecting video-interface and keypad
Connect the female 4pin connector of the keypad to the male 4pin connector of the
video-interface.

2.7. Picture settings
The picture sengs are adjusted by the 3 buons on the video -interface. Press the MENU
buon to open the OSD sengs menu or to switch to the next menu item. Press UP and
DOWN change the selected value. The buons are embedded in the housing to avoid
accidental changes during or aer installaon. Picture sengs must be done separately for
RGB, AV1 and AV2 while the corresponding input is selected and visible on the monitor. AV2
and CAM share the same sengs which must be adjusted in AV2.
Note: The OSD menu is only shown when a working video source is connected to the
selected video-input of the interface.
The following sengs are available:
