F20 pre-LCI ICAM retrofit with NBT EVO

[Dengus]

Hi Everybody,

today i wanna share my resent retrofit with you.
Since i´m always looking for new retrofits i can do to my F20 pre-LCI, this time i wanted to add an rear view camera. Most people would tell me to check wich camerasystem my car expects with 3AG added to VO. Since i´m owning and old F20, it expects an TRSVC wich would be neccessery if i still had the CIC installed. Sadly the TRSVC ECU, CAM and wiring loom would cost me around 400€ used.
Because i already retrofitted an NBT Evo from an 2018 G11, there now are more options to use.

In my case, i chose to add an ICAM camera since this one has the controller integrated and so only needs some extra wires. The hard part was to find a suitable camera. After some research, i found the ICAM of an X5 F15 <11/2015 as suitable. This one works with FBAS and CAN3 on FEM. Additionaly you only need an BMW Evo retrofit wiring loom for X1/5/7 G/F Series ICAM2. Both together costed me around 170€ incl. shipping.


Since there are no housings for ICAM cameras to build into the F20 rear bumper, i had to create my own with a 3d printer from ABS. i added an Matching opening between the lincense plate lights and fixed the housing+camera there.
I put the cable through an plug that was already existing under the rear light on the driver side.

The red power wire was connected to fuse F154 (5A) in the rear fuse box since, this is meant to be used with camera.
the yellow/brown (CAN3_High) and yellow/red (CAN3_LOW) are connected to CAN2 of FEM. I can´t tell exactly why but CAN3 devices also work on CAN2
the FBAS wires are directly connected to the HU Quadlock. Green on 21, black on 23 and white on 24.

now the coding part.
at first you might get confused, since e-sys won´t show the ICAM camera. Because of the gateway table, you won´t see the CAN3 device since it is not supposed to be connected to CAN2. So just continue coding without thinking to much. Create an VO with 3AG added and code HU_NBTevo and REM. Then just FDL code camerasystem from TRSVC to ICAM_rfk in HU_NBTevo
and that´s it. Now you should have an working ICAM on your retrofitted NBT Evo system

Hi! First of all thanks for the info, second, can you specify wich pins do yo used as looking at FEM pinout there are diferents CAN2 pins on FEM like  A173*2B 20 and 21, A173*8B 49 and 50, A173*10B 10 and 11
Thanks in advance!!
