Thanks for the reply. I've just upgraded from 2.x as I was having the trouble back then too. I thought 3.1 might fix it, but no luck. That's why I thought it might be a simple hardware problem such as the usb cable. I hadn't thought of trying the optical cable link from the stereo until just before, so I will have to give that a go tonight. Hopefully it will be just in need of a new usb cable or at worst a new charger cradle.
