Sorry to bump an old thread, but I'm trying to get my iPhone to play music through my Fiesta Zetec S. I've plugged in the USB charger into my iPhone and the AUX lead into the headphone socket on the phone, but I still can't change tracks using the buttons on the steering wheel. I can only control the volume. Anyone know how I can change tracks using the next/previous buttons on the steering wheel?
Try installing this update: http://web.archive.o...udio_update.zip
Then using just the official Apple USB cable on it's own without aux.
