I just recently got the avic d2 and had it installed. But the guy couldn't set it up to allow for steering wheel controls. When I picked it up he said that the steering wheel controls aren't wiring based, but a setup wtihin the navi unit. I looked through the manual but couldn't find anything. Is there some website where it gives me instructions on how to set it up. I really wanna set up the controls, but can't. HELP!

you need the PAC-SWI PS adapter from www.pac-audio.com for it to work with your steering wheel controls
