Hi,

I have a Countryman SE and bought a backup camera kit (https://m.ebay.com/itm/ICAM-BMW-Reve...anner=1&_rdt=1) and received the explanation of the wiring harness in a picture (attached here).

I have the NBT EVO headunit (with touchscreen).

I brought it to a shop and they installed the camera, but could not code it and sent me to a partner shop of theirs for coding. The guy at this shop says it needs a TRSVC module. I read in multiple forums that this kind of camera (ICAM) does not need a module between the camera and the headunit.

can somebody help me with a clear wiring diagram for this camera?
These guys do not have access to ISTA and neither do I.

Thanks!
