Hello everybody.

Is there anybody that can tell me where I can find the speed pulse wire on my Audi A4 so I can get my Pioneer AVIC-X1R up and running correctly? I have switched from the Audio Symphony single CD unit. I have read somewhere that this unit has a speed pulse in one of the ISO connectors. It sounds reasonable since there's an Audi navigation unit that is available as an upgrade for this car. In that case, which one of the wires/connectors is it?

This is the Audi Symphony unit i have removed


And this is the ISO connector diagram for the unit. Are there anybody out there that can tell me if any of these pins/connectors is the speed pulse?


I'm very thankful for any help you can provide me...
