2.6. Connecting peripheral devices
It is possible to connect one after-market RGB navigation (or another RGB video source), two
after-market AV-sources and one after-market rear-view camera to the video-interface.
Before final installation of the peripheral devices, we recommend a test-run to detect a
incompatibility of vehicle and interface. Due to changes in the production of the vehicle
manufacturer there’s always a possibility of incompatibility.

2.5.3. Audio-switch and audio-insertion
This interface is only able to insert video signals into the factory infotainment and switch
audio signals. If an AV-source is connected to AV1 or AV2, audio insertion must be done by
factory audio AUX input or FM-modulator to which the interface’s sound-switch output is
connected. The factor AUX input has to be coded by a diagnostic tool in a car workshop of
the manufacturer’s dealership. 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 activated simultaneously 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 CAN-bus which the included CAN-
box is not compatible with. In this case there are two different ways of installation. If the
CAN-box is able to detect an enabled vehicle’s reverse gear, 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 testing.
2.5.4.1. Case 1: CAN-box receives the reverse gear signal
If the CAN-bus box delivers +12V on the green wire of the 6pin to 8pin cable while reverse
gear is engaged, the video interface will automatically switch to the rear-view camera input
CAM while the reverse gear is engaged.
Additionally, for the camera`s +12V Power supply the green wire of the 6pin to 8pin wire can
be used.
Strip a little part from the green wire of the 6pin to 8pin cable and connect it to the
Power cable of the after-market rear-view camera

Version 23.02.2018 HW:25 (V92) CI-VL2-CONCERT
Page16
2.5.4.2. Case 2: CAN-box does not receive the reverse gear signal
If the CAN-bus interface does not deliver +12V on the green wire of the 6pin to 8pin cable
when reverse gear is engaged (not all vehicles are compatible) an external switching signal
from the reverse gear light is required. As the reverse gear light signal contains electronic
interference, a traditional 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 black 8pin connector.
Isolate the short end of the green wire (CAN-box side).
Connect the reverse gear light signal/power to coil (85) and ground to coil (86) of
relay.
Connect the rear-view camera power wire and the green wire (video interface side)
of 6pin to 8pin cable both to output (87) of the relay.
Connect permanent battery power to input (30) of relay.

2.7. Picture settings and guide lines
The picture settings are adjustable by the 3 push-buttons on the video-interface. Press the
MENU button to open the OSD settings menu or to switch to the next menu item. Press UP
and DOWN to change the selected value. The buttons are placed inside in the housing to
avoid accidental changes during or after the installation. Picture settings 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 settings 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 settings are available:
Contrast
Brightness
Saturation
Position H (horizontal)
Position V (vertical)
IR-AV1/2 (no function)
Guide L/R (no function)
UI-CNTRL (guide lines ON/OFF)
Size H/V (picture size horizontal/vertical)
Note: If there is no communication between the CAN box and the vehicle`s CAN-bus
(several vehicles aren’t compatible), the .reverse gear guide-lines can`t be shown during the
vehicle’s operation, even if they once appear after having switched the system to powerless!
