Hi, Ive recently bought a fiesta s1600 (2011 134ps version) and i'm having trouble with the usb connectivity. I bought a new usb stick (pny 8gb) formatted fat 32 and uploaded some songs in mp3 format. It won't work! It recognises that ive plugged the stick in and then attempts to play, sometimes i get 20 seconds of a song before it says invalid file format. sometimes it plays a whole song then packs in on the next song!! Once its said invalid file format then it won't play anything. If i take the stick out and then plug it back it in starts to work again but then goes through this whole rigmerole again! The file format must be correct as its mp3, and also if it wasn't correct then surely it wouldn't play at all? Seemingly i get more of a song played when its in shuffle mode? Anyone know whats going on?
