iPod interface into a 2008.5 Titan with Navigation

Just picked up the Nissan interface so that my radio/nav system will interface with my iPod. the directions say to go to ASIST.NET for directions, but it seems to be a Nissan factory assist site. My guess is that the installation is straight forward, but before i crack the dash and begin inspecting wiring i was hoping that someone out there in Titan World might have done this procedure before and could offer some ideas/help

Thanks in advance
