Iron Cross Audio  is now offering a hard-wired iPod cable that will allow you to play your iPod through the Harman Kardon Aux circuit as well as charge your pod while connected, all through your iPod connector.

The cable is hard-wired to the main board and exits out the back of the unit much like the rear mounted aux. There is a 4 foot cable terminating with the iPod 30 pin connector. You will select the aux mode to access the iPod audio. Aux port will still be active, but you can only run one device at a time. Power and ground is also supplied from inside the radio. Power to the iPod will be fused for its protection. iPod will be able to be charged with the bike off.
 

Be sure you know the generation of your device when ordering. If you have any questions regarding generation, please contact Apple.
