I pod shuffle ?

I just purchased a new I pod shuffle for my car and it dose not work on the usb port or the auxiliary port.
But my I pod classic works on the USB port.
When the car is in AUXILIARY MODE.

Can anyone tell me that the I pod shuffle works with a 2010 Prius ?

I notice the shuffle only has the headphone jack not like my I pod classic which has the larger square port for a connection and a head phone jack not sure if that has anything to do with it.
