is engaged.
1.3.2.5. Monitor selection (dip 7-8)
The dip-switches are out of function.
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 to “Sleep-Mode”. In case it does not succeed,
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 by flex-wires to the monitor panel and at the rear of head-unit. For
this purpose the housing of head-unit have to be opened.

2.6.3. 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 audio insertion must be done by factory audio AUX
input or FM-modulator to which the interface’s sound-switch output is connected. By
switching video-interface from AV1 to AV2, the audio signal is switched automatically
parallel to the corresponding video signal by the interface’s built-in audio-switch.
The inserted video-signal can be activated simoultaneously to each audio-mode of the
factory infotainment.

2.6.4. 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. Therefore there is two different ways of installation. If the CAN-
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 testing.
2.6.4.1. Case 1: CAN-box supports 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 automatically be switched to the rear-view
camera input CAM while reverse gear is engaged.
Additionally, 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 12.08.2016 VL2-RLINK
Page16
2.6.4.2. Case 2: CAN-box does not support reverse gear
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 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 (CAN-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 battery power to input (30) of relay.

button to open the OSD settings menu or to switch to the next menu item. Press UP and
DOWN change the selected value. The buttons are embedded in the housing to avoid
accidental changes during or after 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.
