I have a new shape ford fiesta with a built in usb slot, with the intention of plugging in things such as iPod, using the usb cable that comes with the ipod respectively, you can connect your ipod to the system. The system recognises that an ipod is connected and allows you to look through songs using the radio controls etc. however when you click play, its comes through fuzzy and the music will not play, has anybody got an ideas on how to fix this?
