1.3.2. Rear-view camera settings (dip 5)
Depending on whether no camera, after-market camera or factory camera shall be used, dip
5 must use different settings.
If set to OFF, the interface switches to factory LVDS picture
when the reverse gear is engaged to display factory rear-view
camera or factory PDC picture. The green wire of the video-
interface’s 6pin power connector must be connected to reverse
light (+12V of reverse light signal) by using a relay, ONLY if
camera shall is (to be) installed.
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 has to be installed into the LVDS leads between monitor control-box and
monitor. The monitor control box is located at A6, A8 and Q7 behind the dash board, at A4
and A5 behind the air-conditioning control panel.

2.3. Installation procedure – function check
Follow the below procedure using the “Connections” scheme from chapter 2.2. as reference.
Before the installation of the sources and the interface we recommend a first quick
connection of the interface and test run to ensure that vehicle and product are compatible.
Due to changes in production of the vehicle manufacturer there is always the possibility of
incompatibility.
- Switch off ignition and disconnect vehicle’s battery
- Disconnect the factory harness’ femaleMitsumi LVDS connector from monitor
control- box and connect it to male LVDS Mitsumi connector of video interface
- Connect female Mitsumi interface LVDS connector male Mitsumi LVDS connector of
monitor control-box
- Connect 6pin power cable to video interface and to power as described in chapter
2.2.
- Connect white wire of 6pin power cable (iDrv) to pin 16 of the 20pin connector from
the monitor control box (alternatively by external switch +12V, see chapter 3.)
- If 2 audio sources shall be used, connect it according to chapter 2.6.
- Connect Mitsumi interface LVDS cable to LVDS IN of video interface
- Reconnect battery and turn on ignition
- Check LEDs on CAN box and video interface, one on each must be on
- Try to activate video sources by infotainment buttons and by external switch (see
chapter 3.), using a test picture source
- If camera is (to be) connected connect green wire of 6pin power cable to +12V to see
whether the automatic switching to camera input works. Later connect green wire to
reverse gear light, using a relay
- If 2 audio sources shall be used, connect the audio wires and check the audio
function
- ONLY after positive function check proceed with installation of the video sources!
- After installation and connection of the real video source(s), adjust picture settings
(see chapter 2.4.)
Note: If the interface is used in combination with the AUX-in interfaces AUX-1xx, the white
iDrv wire can alternatively be connected to the orange activation wire of the AUX-in
interface. Then the AV-inputs will be controlled by the AUX-in interface (see manual of the
AUX-1xx).
Important! Do not connect the white wire additionally to pin 16 of the monitor control box
when connected to the AUX-in interface.

2.4. Picture settings
After installing the sources the picture settings can be changed using a pen on the buttons of
the video interface. Press the MENU button to open settings menu on the OSD and to switch
to the next setting. UP and DOWN change the corresponding values. The buttons are
embedded in the housing to avoid accidental changes during or after installation.
2.5. Audio insertion
This interface can only insert video into the factory infotainment. The video can be activated
to any audio mode of the factory infotainment. If an AV-source is to be connected, the
source’s video out is connected to the video IN1 of the video interface and the source’s
audio out to the audio insertion. Audio insertion is possible by AUX in interfaces AUX-1xx or
Dension Gateway 500 or FM-modulator.
2.6. Connecting 2 AV-sources
If two AV-sources shall be connected, connect the included audio cable to audio-switch-port
of the video interface. When switching the video interface from video-IN1 to video-IN2, the
audio will also automatically be switched.
