iPod alternatives for car audio
 

Hi I have recently bought a Pioneer AVH-A205BT head unit for my VZ Commodore which works great other than it will not support my iPod Classic Gen6 160GB.
When I hook it up it says reading and then gives error 2-60, I contacted Pioneer support and they said it is not supported, only supports the later ipod nano and touches.
I have alot of music so i'm looking for suggestions for an alternative to replace the iPod that gives me similar features i.e. iPod control, nice artwork, playlists etc controllable from the head unit.
I have tried a friends iPod Nano and it works fine but they don't have the capacity I'm after.
TIA
