1.2. Check compatibility of vehicle and accessories
Note: Prerequisite for the faultless functioning of the interface is at least minimum software
version 42.40. The vehicle has to be updated before or after installation if the software
version is lower. You can check the software version of the vehicle as follows:
• Switch on ignition
• Choose radio
• Press „SETUP“ button and hold it
• Press „RETURN“ button in addition to „SETUP“ button and hold it until the monitor shows
„Current Config“
•Choose „Interfacebox“, you can see the software version as „SW-Index“
1.1. Dip-switch settings
With the video interface boxes dip-switches it is possible to dis- or enable the interfaces
inputs (dip 1 to 3) and to preselect the type of camera which is (to be) installed (dip 5).
Dip position down is ON and position up is OFF.
1.1.1. Enabling the interface’s video inputs (dip 1-3)
Only the enabled video inputs can be accessed when switching through the video sources. It

1.1.2. 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 (after-market or
factory) shall is (to be) installed (Relay AC-RW1230 and AC-RS5
optionally available).

3. 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.
The Interface has to be installed into the LVDS leads between monitor control-box and at the
factory CD-changer. 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.
3.1. Connections to the factory CD-changer
Remove the female 8pin Audi connector of the vehicle harness from the factory
CD-changer and connect it to the male 8pin Audi connector of the interface
connection cable.
Connect the female 8pin Audi connector of the interface connection cable to the
male 8pin Audi connector of the factory CD-changer.
Connect the white female 6pin Molex connector of the interface connection cable to
the male 6pin Molex connector of the video-interface.

3.2. Connections to the factory monitor control-box
Connect the interface LVDS cable to the video-interface.
Remove the female 22pin Mitsumi LVDS connector from the rear of the factory
monitor control-box and connect it to the male 22pin Mitsumi LVDS connector of the
video-interface.
Connect the female 22pin Mitsumi connector of the interface LVDS cable to the male
22pin Mitsumi LVDS connector of the factory monitor control-box.

3.3. Connecting optical ring
Remove the black MOST®-connector which contains the optical leads from the rear of
the factory CD-changer. Remove the optical insert from the black connector.
Remove the vehicle harness’ optical output lead (see arrows on MOST®-connector).
With the included optical bridge, connect the removed vehicle harness’ optical
output lead to the optical output lead of the interface’s optical ring (see arrows on
MOST®-connector).
Plug the optical input lead of the interface’s optical ring into the free connector of
the male MOST®-connector on the rear side of the factory CD-changer.
Plug male MOST®-connector of interface’s optical ring into female MOST®-connector
of the video-interface.
3.4. Connecting peripheral devices
It is possible to connect 2 after-market AV-sources, an after-market rear-view camera and an
after-market navigation to the video-interface.
Before final installation of the peripheral 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.

3.4.1. AV-source(s)
The c.LOGiC interface has the possibility to connect and remotely control by navigation
buttons up to 2 pre-programmed devices. The device list in the device control table
(appendix A) shows the pre-programmed remote channels and the related IR-control cables
STA-xxx which must be ordered separately for the control of the device.
Note: The two fix pre-programmed IR control channels are listed on the sticker on the back
of the video-interface.
Using the respective STA-xxx IR-control cable, interconnect the blue female 3pin AMP
connector of the interface connection cable and the IR-port of the AV-source. If 2 AV-
sources will be connected, plug the optional available IR-cable STA-Y between it.
Connect the video-RCA of AV-source 1 to the RCA-port IN1 and the video-RCA of
AV-source 2 to the RCA-port IN2 of the video-interface.
Connect the female 8pin connector of the audio cable zo the male 8pin connector of
the video-interface.
Connect the audio-RCA of AV-source 1 to the RCA-port AV1 and the audio-RCA of
AV-source 2 to the RCA-port AV2 of the audio cable.

Note: When switching the video interface from video-IN1 to video-IN2, the at the integrated
audio switch connected audio signal will also automatically be switched.
3.4.2. Installing AV-source’s IR-sensor additionally
Additionally to the control via OEM navigation, it is possible to install the original IR-sensor
of a connected device. By using the respective Y-adapter (e.g. STA-Y35MM or STA-RJ12) for
the IR-Port of the connected device, the controls of navigation AND device’s IR-sensor can be
connected and used simultaneously. Installation of the IR-sensor is recommended as the
controls via navigation are limited, and not all functions may be covered.
3.4.3. After-market rear-view camera
Connect the video-RCA of the after-market rear-view camera to the RCA-port CAM of
the video-interface.
-The grey wire of the interface connection cable is not connected and has to be
isolated. Connect the green wire of the interface connection cable cable to +12V to
see wether the automatic switching to camera inputs work. Later connect green wire
to reverse gear light, using a relay.
Note: Set Dip 5 to ON.

3.4.4. After-market navigation
Connect female 8pin connector of the RGB cable to the male 8pin connector of the
video-interface. The loose grey and the loose green wire have no function and have
to be isolated.
Connect male 6pin connector of the RGB cable to the after-Market navigation. The
loose blue wire has no function and has to be isolated.
3.5. 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.

4. Operation
4.1. Video-in-motion function
The video-in-motion function for the fed in video-signal is activated permanently without
disturbing the navigation performance.
4.2. Selecting the c.LOGiC as current AV-source
After installation the c.LOGiC is identified as factory CD-changer
and is displayed as virtual (second) CD-changer in the “CD/TV”
and accordingly the “MEDIA” (in vehicles from year 2007) menu,
sub-menu “Changer” and is shown as “CD7 – VIDEO”.
Select ”CD7 –VIDEO“ by pressing the knob. The display shows
“01 – ON: - >“ and “02- OFF: - <“. The MMI switches to the first
activated input by pressing the “>” button. Each press of the “>”
button will switch to the next enabled input.
Disabled inputs will be skipped. If all inputs are enabled the
order is:
Factory video  RGB-in  AV-IN1  AV-IN2  Factory video  …
Pressing the “<” button will return to the factory video mode of the MMI navigation.
Note: Please note that no repeat function is activated in the
Setup CD mode, otherwise it may get error messages.

4.3. Device control
After selecting the c.LOGiC as current AV-source it is possible to
control the 2 fix pre-programmed devices by the knob of the left panel
of the steering wheel.
The display of the FIS shows the available functions among each other
(first for AV1 and under it for AV2) in the CD-changer menu.
The functions of the device can be selected by scrolling the knob
and the selected functions can be executed by pressing the knob.
The function description equals the remote control buttons of the
device’s remote control. On the additional device the writing may
vary (e.g. AV instead of Source).
