I got the same story from PAC when I emailed them. I read somewhere that it worked with the 05 Frontier, which offers the exact same HU. (You'll notice on PAC's website that they've since added the Fronty to their compatiblity list) So yeah, I took a calculated risk, but I was pretty sure it would work.

The adapter only offers the inputs, not specific support for the Ipod. I have the little wired remote you can buy for the ipod, so I use that and the clickwheel. I also bought the Belkin car lighter adapter, which includes an integrated amp for the ipod, so I can charge it and greatly improve the sound quality.

To clean up all the wires, I ran the audio cable from the dash, along the center console, and up into the console storage area, and into the belkin adapter is plugged into the lighter outlet. It's not a flawless job, but it works great for me without drilling holes, etc.
