Any reason you can't just run a cable from the AUX inputs to a 3.5mm socket? I was planning to do this sometime over the next week, so if you know of any reason it can't be done please let us know. Otherwise I'll let you know how it goes.
I don't have a fiesta but I got an ipod adapter from Nano Rider that works great in my car... I tried to look up the fiesta but I realized that nowhere in your post did you mention a year so I couldn't properly search for it... sorry
Genuine Ford part can be bought for this online, roughly a tenner. Matter of just sliding out the radio, attaching it and deciding where u want the input. It is just a 3.5mm connection for all mp3/dvd players.
