I was listening to music using a USB stick. Unfortunately I pressed the button which produces a playlist based on the track currently playing. I didn't want this! There are 4500 tracks on the stick but now I'm stuck with just 100 of them. How do I tell the system to cancel this? There doesn't seem to be a way at all. Been back to the dealer, but they were as baffled as I am. I've tried removing the USB stick, putting a different one in, then putting back the original. It just resumes the track it was playing. (Too clever for it's own good). Anyone got an answer?
