Video only The interface inserts ONLY video signals into the infotainment.

For sound use the possibly existing factory-audio-AUX-input or a
FM-modulator.

1.2. Checking the compatibility of vehicle and accessories

1.3. Dip-switch settings

With the video interface boxes dip-switches it is possible to select vehicle/navigation the
interface is to be installed in (dip 7 and 8), to select the video signal of an optional connected
after-market navigation (Dip 4), 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.

1.3.1. Vehicle selection (dip 7-8)

Choose the vehicle/navigation/monitor the interface is to be installed to and set dip 7
through 8 according to the below table.

1.3.3. Enabling the interface’s video inputs (dip 1-3)

Only the enabled video inputs can be accessed when switching through the video sources. It
is recommended to enable only the required inputs for the disabled will be skipped when
switching through the video interfaces inputs.

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.

If a rear-view camera will be or is connected (factory or 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).

1.4. Dip-switch settings of the CAN-box

All 4 dip-switches of the CAN-box have no function for normal use
and must be be set to OFF.

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 head-unit.

Symptom

Reason

Possible solution

Camera input picture
black.

Camera power taken directly
from reverse gear lamp.

power. Alternatively, if CAN-bus box is compatible
with the vehicle, camera power can be taken from
green wire of 6pin to 8pin cable.

Camera input picture
has distortion.

Camera input picture
settings cannot be
adjusted.

Camera input picture settings
can only be adjusted in AV2
mode.

Function RET or ALL is ON
(function for Asian market) in
the interface OSD.

Set interface OSD menu item UI-CNTRL to ALLOFF or
PDCON.

Not possible to switch
video sources by OEM
button.

CAN-bus interface does not
support this function for
vehicle.

Use external keypad or cut white wire of 6pin to 8pin
cable and apply +12V impulses for AV-switching.

Pressed too short.

For video source switching a longer press of about 2.5
seconds is required.

Not possible to switch
video sources by
external keypad.

SW-version of interface does
not support external keypad.

Use OEM-button or cut white wire of 6pin to 8pin
cable and apply +12V impulses for AV-switching.

Interface does not
switch to camera input
when reverse gear is
engaged.

CAN-bus interface does not
support this function for the
vehicles.

Cut the green wire of the 6pin to 8pin cable and apply
+12V constant from reverse gear-lamp signal. Use
relay to "clean" gear lamp power.

Interface switches
video-sources by itself.

CAN-bus interface
compatibility to vehicle is
limited.

Cut the grey wire of 6pin to 8pin and isolate both
ends. If problem still occurs, additionally cut the white
