1.3.4. 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.
Note: If the Can-bus does not work while connecting an after-market rear-view camera, cut
the green cable of the 6pin to 8pin cable at the black 8pin connector and connect it to the
reverse gear light (+12V). For this use a relay because the reverse gear light of the vehicle is
clocked (relay AC-RW1230 and AC-RS5 optional available).
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. 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
-Remove vehicle monitor
-Connect 4pin cable of CAN-box to the 8pin power connector of the factory monitor
as shown in chapter 2.2.
-Plug 4pin harness into CAN box
-Plug 8pin female connector of 6pin to 8pin cable into CAN box
-Transfer vehicle harness’ 10pin LVDS connector from factory monitor to male 10pin
connector port of the LVDS switch-box
-Connect female 10pin LVDS connector to 10pin LVDS connector port of the factory
monitor
-Connect LVDS Switch box to the video interface
-Plug 6pin female connector of “6pin to 8pin cable” into video interface
-Plug keypad into “Switch” connector. Even if the keypad shall not be used, its
installation (e.g. in a hidden spot) is recommended for support reasons
-If audio insertion shall be used, connect it according to chapter 2.5.
-If audio switch SW-A2X1 shall be used, connect it according to chapter 2.6.
-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 Comand-buttons (see chapter 3.1.) and by keypad
(see chapter 3.2.), using a test picture source
-If camera is (to be) connected try to engage reverse gear with test picture source
connected
-If audio switch SW-A2X1 shall be used, connect the audio wires and check the audio
function

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 factory audio AUX input or
FM-modulator. The factory audio AUX can be coded by the dealership.
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.
