Initially, the stereo expert merely plugged the two standard plugs sticking out of the car into the standard adapter that came with the stereo.
Apparently, he says, although the plugs are standard shapes, the semantics of the various pins are insufficiently well defined, and the Clio was sending a signal down one of them when the car moved, but the Dension was expecting to interpret a signal on that pin as an incoming phone call.
So my guy simply cut the relevant wire (a tricky procedure in itself, since there were two identical pink wires going to that pin on the car side of the connector, and he knew which one to cut). But it certainly looked a lot more to me as he performed a hacky workaround for a standards problem than as if he screwed up something well-defined.
Yeah, the ISO blocks are similar to SCART blocks, in that only half the pins are nailed down precisely, and the others are at manufacturer discretion. The most common ones to find mixed up at the connector blocks are the interrupt and the powered aerial. (pastel pink and pastel blue, both with white stripes)
Car wiring has always been entertaining. I don't know if they still do it, but in all the older Vauxhalls the positive leads were black and the grounds were brown. I thought that was a bit confusing... I set fire to a dashboard learning that one :)
