A few days ago I was reading a thread somewhere here on the TDR about a device that allows for the steering wheel controls to operate on aftermarket head units. The product is from Crutchfield and believe it was made by an outfit called Soundgate. I believe the posts said the device is not a listed product in the catalog but if you call and ask a tech they should be able to pull it up in the computer system. This product may not be common knowledge amoung the cruthfield staff, so you might have to talk to more than one person find it. Hope this helps
