I was looking on crutchfield and came across this. I know that alot of people have given up the convience of their wheels control when they got new audio equitment, however this product claims to let you use your existing controls.

Yes it does let you use the factory wheel controls. You tap the wires from the steering wheel controls, the box converts it to IR signal (like a normal wireless remote). You need to mount the remote eye somewhere where it can point at the radio. Hope that helps any.
