I have a 30gb ipod video. It charges fine through usb 2.0 but won't charge through an offical ipod wall charger or when its on my inmotion im3. I left it on the inmotion and it completly drained the battery and I had to charge on usb to get back it life. I know both the mains and inmotion are fine as I use them with my ipod mini, does anyone have any ideas. I just fitted a dension kit to my car and now the ipod won't charge either...
