Here are a few thoughts on this. When working on some vehicles with a factory installed steering wheel controls, there is what is some times called a "Clock Spring" behind the steering wheel inside the column, that winds and unwinds the wires for all the controls in a factory steering wheel. So if this is what you want, you would have to replace the steering column along with the radio. Unless the factory controls for the newer radios are now wireless. But you would sill have to adapt them to your vehicle.
On the other hand if you installed a new Radio with a hand held remote control, you can get an attachment to the steering wheel to add a remote to take the place of the hand held control. I looked this up on the internet, and found a steering wheel adapter in a few seconds.
I am assuming that what you want to do would require a new radio.
