I can run my iPhone 4 directly in to my Suburban's stereo system with an iSimple system that plugs directly into the iPhone and I can also switch over to an aftermarket XM/Sirius radio as well. I like being able to control the iPhone with my steering wheel controls. I really would like to get the Note 2, but want to know if there is something out there that would let me do the same thing with it. I tried an adapter that goes from 30 pin to micro USB on my my old Droid X, but it just charges. I know one option is to just unplug the XM/Sirius and plug into the phones' headphone jack, but then all I get is volume control. I want my cake and eat it too. Does anyone know of anything? Thanks!
