It was actually pretty easy. I ended up ordering the GMSW1 from Crutchfield (you can find it cheaper at other places). This is the GM converter which will hook up to the control wire from your steering wheel. Then you just plug in the mini-jack into the radio module which is then hooked up to the empeg. The only big problem I had was solved very quickly by Hugo sending me a beta of the player software. It works great! If you need more help, just let me know. I may actually take some pictures of my setup and post it up on my website.

cheers
