This is the reason I joined this site, to find this out. I have a Ford Fusion with the SYNC, and want to get this to replace the stock HU but still use my steering wheel buttons. My only thought at this point is this - Do they make a steering wheel remote for this unit? If so, the PAC Universal Steering wheel control is a learning setup, and can emulate any of the buttons on the remote to the steering wheel. Which would give my SYNC button the same functionality with the Avic, as well as the phone and source buttons....
