Scion Ipod Help!!!!

[Pirate VI]

Hey guys I just installed the Scion HU with iPod controlls in my truck this morning, but i seem to be missing a part to the cable that connects to the iPod.
Anyone install this and know what goes on back there??
it seems that the connectors on the back of the radio are all female, and the cable I have (two parts actually) also has a female connector. I must be missing a piece? Additionally I am unsure of the piece I am missing because I do not exactly know what port inthe back of the HU, the ipod cable plugs into. (changer port?) So basiccally if anyone knows the part I am missing or at least where the cable plugs in I would greatly appreciate it.
Im dying, i just installed it but it is not working all the way AAAHHHH!!!!!

Heres the cables that I have. Notice the white connector at the end looks like the connectors that plug into the ports in the back of the HU, but it doesnt fit anywhere... they are both female i think.
