Yes, it's a Pioneer.
I think I was wrong - I do in fact need to the regular ISO to Din converter - think the Fakra connections are for the newer Sony CD6000.
Thanks - will do.
One other question, my Corsa steering controls allowed me to adjust volume, change from radio/iphone and skip tracks/stations of my Pioneer. I'm tempted to add the stalk controls to my fiesta and then buy the following: http://www.ebay.co.uk/itm/250951115764 but would this likely give me full functionality and would it mean I'd lose the odometer, mpg readings etc? Although reading that, it does mention the fakra connection again and there appears to be two variations - one with ignition wires, and one without. How would I know which I need?
