BMW-to-ISO connectors (and vice versa)

[SD1too]

Thanks for the larger, clearer pictures Dougie. Although the third picture is out of focus I have deduced that the missing socket appears to be no. 4 which is the left rear loudspeaker signal.

I don't have any information to hand on the VDO unit I'm afraid. I'll have a look round later this evening.

Yes, the pin numbering on the Carav diagram is completely different from RAVE! However their positions are correct.
As I see it, if you use that 13 pin connector you will need to install conductors in the empty sockets for the following:

Pin 4 NSR speaker signal
Pin 7 K-bus
Pin 10 Steering wheel switches +ve
Pin 17 Steering wheel switches -ve

Any help?
