So I hooked everything up tonight just to test it out. I ordered an RCA to 3.5mm cable over the weekend, but it won't be here for a couple of days. Anyways, I wanted to see if the AUX would at least show up on the radio without it, but it was a no go. Kind of disappointed, really want to at least know I'm moving in the right direction here.

Should the AUX output have shown up if power was going into the PAC?
