1. Switch off ignition and remove the key.
2. Remove and disconnect the head unit.
3. Release the fibre optic cables from the main connector of the head unit (pic.1), and pull out thesmall
connector (pic.2). Afterwards push out the blue locking (pic.3), and then pull out the fibre optic from the
output (!) (see the right arrow on pic.4), while carefully bending the clip with a small screw driver. Then put
E
this fibre optic into the connector from the enclosed fibre optic cable kit (pic.5, this connector must lead to
N
the input of IMU 670848 on its' other end via the fibre optic!!) The remaining fibre optic without connector
G
now has to be plugged into the open slot (pic.6). With that, the fibre optic ring must be closed entirely again!

4. Re-connect the small fibre optics connector with the main connector.
5. Connect the remaining fibre optics connector (pic.7) with the counterpart at
the IMU 670848.
6. Now connect the black wire from the harness with ground
and the red one with "permanent" +12V.
7. Connect RCA jacks - A: audio left (black), B: audio right (red),
with the audio output of the video source. The yelllow
RCA jack (C) is only used when the video source delivers
a NTSC signal. Connection with the video source should only
be done with a high quality RCA video cable, otherwise the
picture quality could be bad, caused by a weak video signal.
The video output signal (CVBS) is fed into the head unit
directly by using the enclosed "green FAKRA to RCA jack"
adapter (see picture).
8. If it is intended to use the AIV DVB-T 190860 or the AIV DVD 190861, the control cable kit 670846,
670847 or 670864 has to be connected with its' counterpart at the video source and the IMU 670848.
9. Refit the head unit.
10. Activating the TV input: Press "VIDEO" and select "TV" with the soft key. "AV1" and "AV2" can be
selected and used as well, but use of the buttons for controlling the connected source is not possible
in this mode!
