2. Installation
To install the interface, first switch off the ignition and disconnect the vehicle’s battery.
Please read the owner`s manual of the car, regarding the battery`s disconnection! If
required, enable the car`s Sleep-mode (hibernation mode)
In case the sleep-mode does not succeed, the disconnection of the battery can be done
with a resistor lead.
If the necessary stabilized power supply for the interface is not taken directly from the
battery, the chosen connection has to be checked for being constantly stabile.
The interface needs a permanent 12V source!
Note: Before a final installation, we recommend a test-run to ensure the compatibility of the
vehicle and the interface. Due to changes in the production of the vehicle manufacturer
there’s always a possibility of incompatibility.
2.1. Place of installation
The interface should be installed on the backside of the head unit.
Because in some cars the space available may be very limited, special care must be taken
with regard to cable crushing, etc.

2.6.1. 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.
2.6.1.1. 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
“CAMERA-IN”while the 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 09.02.2023 HW: CAM(V31)9275&9276(V11) since serial-no. NA210400258 with frontcam input RL2-SC14
Page15
2.6.1.2. . Case 2: CAN-box does not receive the reverse gear signal
If the CAN-bus interface does not receive +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 and
isolate the shorter end of the green cable near to the 8pin connector (CAN-box side).
Connect the reverse gear light signal/power to coil terminal (85) and vehicle’s ground
to coil terminal (86) of relay.
Connect the rear-view camera power wire and the green wire (video interface side)
of the 6pin to 8pin cable both to output terminal (87) of the relay.
Connect permanent battery power to input terminal (30) of relay.
Note: If, due to a missing CAN communication, the 6pin to 8pin cable has been connected
the analogue way instead of the Can box, the green wire’s connection has also to be done as
shown in the picture above.

2.6.2. After-market front camera
The red coloured power supply output „Power for front“ which is coming from the
front camera relay can be used to power a front camera. If Dip 6 is set to ON, the
power supply output gives +12V (max 3A) when reverse gear is engaged incl. 10
seconds delay after reverse gear is disengaged.
Note: If the front camera/V1 video input „Video IN 1“ is activated by Dip-2, it is also possible
to switch manually from any picture mode to the front camera input, by pressing the button
of the external keypad (2-3 seconds).

2.6.3. Audio Insertion
This interface can only insert video signals into the factory infotainment. If an AV-source is
connected, audio insertion must be done by factory audio AUX input or FM-modulator. The
inserted video-signal can be activated simultaneously to each audio-mode of the factory
infotainment.
2.7. Connection Video Interface and external keypad
Connect the 4pin female connector of the external keypad to the male 4pin
connector of the video interface.
Note: Regardless if it’ll be used or not, the external keypad should always be connected! In
case of non-using, it should be invisibly hidden together with the video interface.
