3. Installation
Switch off ignition and disconnect the vehicle’s battery! If according to factory rules
disconnecting the battery has to be avoided, it is usually sufficient to put the vehicle in
sleep-mode. In case the sleep-mode does not show success, disconnect the battery with a
resistor lead.
Place of installation is behind the head-unit.

3.1. Interconnecting Interface-Box, harness and head-unit
Plug harness RLC-VN01 into 12pin Molex of Interface-box RLC-M02.
Plug male 10pin DIN-connector of RLC-VN01 into female 10pin DIN-connector of
head-unit.
If connecting an AV-source:
Connect red wire of harness RLC-VN01 to +12V ACC and black wire of harness
RLC-VW02 to ground. Connect the blue wire to +12V ACC by using the interface with
Audi Navigation Plus, do not connect the blue wire with VW MFD1.
If connecting a rear-view camera:
Connect red and blue wire of harness RLC-VN01 to +12V reverse gear light (we
suggest to connect through relais to avoid signal noise) and black wire of harness
RLC-VW02 to ground.
Note: If the female 10pin DIN-connector of the head-unit is already occupied, the vehicle has
a factory TV-tuner. In this case it must be uninstalled: disconnect the male 10pin DIN-
connector of the factory harness and disconnect all wires from the factory TV-tuner.

female video RCA-connector of harness RLC-VN01.
If connecting an AV-Source, connect the audio RCA of the AV-source to female audio
RCA-connector of harness RLC-VN01.
Note: The interface is initialized to PAL. Cut and isolate both
ends of the brown cable of harness RLC-VN01 if you want to
