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.
Deviation BMW i3: With installation in BMW i3 the PNP cable requires an extention to the
video interface, as its head unit is located in the rear of the vehicle.
The installation place of the video Interface remains in the front of the vehicle.

Page12
2.6.1. Switching of picture formats
Short press OPTION-button to switch the picture format.
2.6.2. After-Market Rear View Camera
Some vehicles have a different reverse gear code on the Can-Bus, which is not compatible to
the CAN-Box included in the scope of delivery. For this reason there are two possibilities of
installation. If the Can-Box supports the reverse gear, the green wire of the 6Pin to 8pin
cable is occupied by +12V, as long as the reverse gear is engaged.
Note: Before testing, please, don’t forget to shift the Dip 5 of the Video Interface to ON.
2.6.2.1. Video signal connection of rear-view camera
Connect the video-RCA of the after-market rear-view camera to the female RCA port
of the video-interface which is labeled as CAM.

Version 26.04.2021 HW CAM(V31)/(V71) RL2-NBT
Page13
2.6.2.2. Case 1: CAN-Box supports Reverse Gear
In case the Can-Bus-Box delivers +12V to the green wire 6Pin to 8pin cable while reverse
gear is engaged, the Interface switches automatically to CAM input.
In addition power supply of +12V (500mA max.) of the After-Market Rear View
Camera can be realised by the green wire of of 6Pin to 8pin cable
2.6.2.3. Case 2: Can Box does not support reverse gear
In case the Can-Bus-Box does not deliver +12V to the green wire 6Pin to 8pin cable while
reverse gear is engaged (not all of the vehicles are compatible) an external switch-over signal
of the reverse light will be required. Because of the fact that the reverse light signal is not
free from electronic interferences, a relay (eg. AC-RW-1230 with AC RS5 wiring) or an
interference filter (e.g. AC-PNF-RVC) will be required. The diagram below shows the use of
the relay.
Disconnect green cable of 6pin to 8pin cable near the black 8pin connector .
Isolate short end of the green cable (CAN-Box side).
Connect Reverselight/Power with Coil (85) and Ground (86) to relay.
Connect power of rear-view camera and the green cable (Video Interface side) of
6pin to 8pin cable with relay output (87)
Connect continuous battery current to relay input (87)
