With Navi Business you will not have a problem, but with the FEM, because it needs to be changed to one for rear view (this only has the K-CAN1 to work with the ECU). In ETK you will see, that there a 2 different FEMs.

I have done the retrofit on my 04/2018 F30 with no navi at all, and using the K-Can1 wires on FEM (51,52), and it works just fine.

I used this wiring diagram

I used this ICAM : 66536999277 but, I should have used 66539109855 or newer. Check RealOem for the correct part number for you build date. Mine works, but ISTA will have it replaced before it can do SW update.

Hello,
I want to retrofit a rear view camera at a BMW F23
VIN of this car is: VE47315

This car do not have the Professional (SA 609) it only hast the Business (SA606)
Is it possible to retrofit fit the original rear view camera without SA609?

The part list this I think I need:
 - Rear View camera 66539475684
- Rear View camera ECU 66536994555 or can I also use a TRSVC for rear view camera?
(Then I would coding out the not used signals? So retrofit later other cameras would be better)
- also need the cabels for connecting

The main questions is that I need to know if I can retrofit the camera at this car or if I need to change something on the Navigationsystem. If I need to change what I need to change for the retrofit?

Oh, and you only need the ICAM, no need for TRSVC ecu. Camera is connected directly to Headunit.

I guess you also has HU_EntryNav2 headunit ?
