I spent all afternoon doing a double-din install on my 2004 sedan. Installed the DD bracket, AC control unit, DD finisher, and PAC SWI-X. When I turned on my HU, everything works fine, but there's no sound. I checked my wiring harnesses, and I'm pretty sure I hooked everything up correctly. I haven't tested the SWI-X yet, so I'm wondering if that has to do with it. I tried to follow the instructions with all the resistors and such, so I think I did it right. I also noticed that there's an extra loose 12-pin harness; I'm guessing that's for SAT, and since I don't have it, it should be okay hanging loose. I also used the Scosche Nissan Diversity Antenna Adapter, but noticed that I only have 1 antenna cable (2 prong), so the smaller receptacle on the adapter is empty.

Does anyone have any idea what I might be missing? It's driving me insane having everything complete, but no sound!!!
