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 on rear of the head unit.
3.1. Interconnecting interface-Box, harness and factory head unit
Connect female 12pin Molex connector of harness RLC-POR03-2 to male 12pin Molex
connector of CAN-box RLC-M40-2.
Remove the female Quadlock connector of the vehicle harness from the rear of the
head unit and connect it to the male Quadlock connector of harness RLC-POR03-2.

Connect female Quadlock connector of harness RLC-POR03-2 to the male Quadlock
connector of the head unit.
3.2. Connections to after market rear-view camera
Connect the video RCA of the rear-view camera to the female RCA connector with the
label „Rear-view camera“ of RLC-POR03-2 harness.
Connect the green cable of harness RLC-POR03 to the camera power supply (+12V
max 1A). The green cable is high when reverse gear is engaged (if ignition is off, too).
The power will be deactivated from a speed of 20 km/h.
Note: Only compatible with NTSC-cameras.
3.3. Connections to OEM rear-view camera
Connect the male RCA plug to the female RCA connector with the label „Rear-view
camera“ from RLC-POR03-2 harness.

4. Coding of the camera function
4.1. Coding of the rear-view camera (only PCM3.1)
It is necessary to code the rear-view camera input of the PCM 3.1 to use it for an after-
market rear-view camera.
1. Turn on ignition
2. Wait until the head-unit has booted
3. Press and hold steering-wheel button HASH KEY/MODE
4. Press and hold steering-wheel button ACCEPT (observe the sequence!)
5. Hold both buttons. During configuration the red and
blue LED are blinking short inside the CAN-box (visible
at the male 8pin Molex connector). The PCM makes a
reset after 5-10 sec.
6. Disengage both steering-wheel buttons
7. The red and the blue LED inside the CAN-Box are
glowing and the menu „Rear-view camera“ appears in
the menu OPTION after a successful coding
4.1.1. Decoding of the rear-view camera (only PCM3.1)
It is possible to decode the coding of the rear-view camera input as follows:
1. Turn on ignition
2. Wait until the head-unit has booted
3. Press and hold steering-wheel button HASH KEY/MODE
4. Press and hold steering-wheel button HANG UP (observe the sequence!)
5. Hold both buttons. During configuration the red and blue LED are blinking inside the
CAN-box (visible at the male 8pin Molex connector). The PCM makes a reset after 5-
10 sec.
6. Disengage both steering-wheel buttons
7. The red and the blue LED inside the CAN-Box are glowing and the menu „Rear-view
camera“ disappears in the menu OPTION after a successful decoding

4.2. Optionally coding of ParkAssist to retrofit factory PDC (only PCM3.1)
It is necessary to code the ParkAssist of the PCM 3.1 to retrofit factory PDC.
1. Turn on ignition
2. Wait until the head-unit has booted
3. Press and hold steering-wheel button BACK
4. Press and hold steering-wheel button ACCEPT (observe the sequence!)
5. Hold both buttons. During configuration the red and
blue LED are blinking inside the CAN-box (visible at the
male 8pin Molex connector). The PCM makes a reset
after 5-10 sec.
6. Disengage both steering-wheel buttons
7. The red and the blue LED inside the CAN-Box are
glowing and the menu „ParkAssist“ appears in the
menu OPTION after a successful coding
4.2.1. Decoding of the ParkAssist (only PCM3.1)
It is possible to decode the ParkAssist as follows:
1. Turn on ignition
2. Wait until the head-unit has booted
3. Press and hold steering-wheel button BACK
4. Press and hold steering-wheel button HANG UP (observe the sequence!)
5. Hold both buttons. During configuration the red and blue LED are blinking inside the
CAN-box (visible at the male 8pin Molex connector). The PCM makes a reset after 5-

4.3. Alternatively coding and decoding of rear-view camera and ParkAssist (e.g. if
steering-wheel buttons not existing, only PCM3.1)
Alternatively to coding by steering-wheel buttons the coding and decoding of rear-view
camera and ParkAssist can be done by DIP 5 in conjunction with DIP 3 and 4 of interface-box
RLC-M40-2.
1. Set DIP switch “5” to OFF position
2. Turn on ignition
3. Wait until the head-unit has booted
4. Set DIP “3” and DIP “4” of CAN-box (depending on the desired coding/decoding)
5. Set DIP switch “5” for 5 sec. to ON position
6. During configuration the red and blue LED are blinking
short inside the CAN-box (visible at the male 8pin Molex
connector). The PCM makes a reset after 5-10 sec.
7. The red and the blue LED inside the CAN-Box are
glowing and the menu „Rear-view camera“ respectively
“ParkAssist” appears in the menu OPTION after a
successful coding (or disappears after successful
decoding)
Note: After a coding or decoding another coding isn’t possible within the next 60 seconds!
If there are factory-PDC existing in the car you have to set DIP 4 to ON while coding. If not
the factory PDC will be decoded!
