yeah. id rather just get a rca to mini. and go in to aux.
the only ipod interface i really like is the fullspeed one alpine makes. quick and easy to use. and its just a single cable.
we usually do not sell pioneer, but we got a Land Rover Defender in the shop that was already worked on, and our job was to get the system and everything working again. And it had a pioneer deck (7700 i think) and we tested it with an ipod when we were done, it was a PITA to cycle through the songs, etc. and not the fastest thing, IMO it's not worth it, unless you have like a motorized screen for it, with better controls. I would try to find another alternative
