Using an iPod for the AUX?
 

I noticed my radio has an AUX button and I can't quite figure out how to use it with my iPod. How does that work, like would I need to wire something to use it, or is there something i'm missing? Oh and I have an '07 Accord SE sedan. Thanks

There is a socket on the back of the radio, you need to buy the interface that gives you an input. silly, i know.

These manufacturers make good interface products:
USA Spec
Grom
PAC-Audio
