Requirements
Vehicle Vehicles generation NTG4.5
Head-unit/monitor Comand Online NTG4.5, Audio20 NTG4.5
with 4pin HSD LVDS connector on the monitor
Limitations
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 (exception: Comand Online NTG4.5 without
factory media-interface).
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)

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.
Note: If the Can-bus does not work while connecting an 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).
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 factory monitor and on the backside of the
head-unit.
