You need to put in a shunt at the wire harness in the rear of center console... should be a flat wire harness with three wires even though it has capability for 4... connect the outer two together.

Have changed my old OBC with watch+temp to full OBC (also from e34, but 530)- everything work fine except stalk with remote control (turn swith and upper beam works fine).

I have already looked there - no 3-wire harness
Then your car is not prewired for cell phone... therefore you don't have that option unless it is in another location.
I don't think the cellphone has anything to do with the obc retrofit... I retrofitted the obc, my new indicator just pluggged straight in to the connections with the old one and brings up the obc functions.
prewired for the cell phone so he does have to jumper the connector

yes they do. Cell phone uses that signal stalk to answer phone... you can either have cell phone or OBC control but not both. The shunt that I was talking about is where they plug in the cell phone unit... alot of time when reconverted back to normal... people lose that shunt or don't know about it... therefore it doesn't work.
Maybe smb. know what colours are these 3 wires?
I think mine were yellow... yellow with red stripes. I know there are different colors depends on year of your car. In any case, it is the only loose wire harness under the center console. Sometime you just have to take off the rear of center console to see the wires.
