I've checked with a few stores like Radio Shack and Circuit City, and they said they were sure it was to an aux out jack to a Sirius radio

the other two are for the antenna and the power (if that wasn't already deduced)

and I bought an adapter so that it will fit into a standard stereo jack, I just don't have it on in the pic. I'm thinking that if I can't find any help I may just buy an adapter kit to play and control my iPod through the factory stereo.

If I do choose to do so, are there any ideas for that? Brands to go with, easier ones to install, etc.?
