Using steering wheel controls?

I did try and search, didnt seem to come up w/ what I'm looking for. First, I would loooveee to be able to control the volume of my panasonic HU using my volume controls on the steering wheel. It does come with a remote and I know i read somewhere of something that could be used for this. At the same time I would love to be able to control the channels on my XM roady2 using the channel button on the steering wheel... Are there any car stereo gods out there to suggest which route to take when doing this?

What vehicle is this going into? You can try these links: http://peripheralelectronics.com/2002/steering.asp http://www.pac-audio.com/products/swi.htm ~wirewise~
