You can always modify the wiring to the controls, but the real issue is what can you do with the aftermarket head unit. I would go to a website or a forum that knows that particular unit. Find out if it will accept commands from the controls. I would look at what the three wires control and how it accepts the commands. Then see if the steering wheel switches are capable of giving those type of commands - simple on / off or combinations of those are about all you are going to get though.------------------------------------------I would also look at this link and consider putting in a factory unit.
