New Fiesta Ipod problems

[Guest]

My ipod has worked fine in my new fiesta for over a months but the other day I was playing it and a song stopped halfway through it, I looked at the Fiesta screen which said 'line in active.' Now when I start my car the ipod does not start playing automatically as it used to, instead it stays at the 'line in active' screen & I have to press the AUX button again to get it to recognise my ipod. Then instead of just playing my songs as normal, it just seems to keep flicking through songs not playing any of them. I then tried my mates ipod & it worked fine. I cant understand as my ipod had been working for over a month and I haven't updated my ipod or anything. See this video if it will help you better understand my problem.

Also could someone please tell me the default settings for the new fiesta menu and is there any way to restore the system to the factory default settings?
