ya, you have to get the steering wheel, clock spring, and have the dealer program the computer to tell it you have steering wheel controls.
Its a pretty expensive project considering it was a 125.00 add-on from the dealer when the truck was originally purchased. My truck doesnt have them either. I actually bought a new wheel and was going to do it, but lost interest since im going to go to an aftermarket stereo anyway. So I sold it on eBay.
