So In two weeks I'm getting my head unit installed, set up the appointment today. But what I need to know is what steering wheel interface kit do I need to interface a JVC KD-r900. The guy at the store said a PAC SWI-RC would work but I went on to PAC's website and it doesn't have the KD-r900 listed as one that it's compatible to. But when I bought the head unit the JVC website said "steering wheel remote ready, with an optional adapter you can use you're factory steering wheel controls" Here's the link. Any help would be greatly appreciated.
