There are a couple of adapters out there that will work for the steering wheel controls, but I believe that they are brand specific. Either the Grandprix store or Club GP's website have them listed. Could be a DIY easy install. Some shops may also be able to convert your stock deck to have pre-outs, but I wouldn't reccommend it, since it doesn't send full range sound to either speaker (stock deck limits bass from fronts, and limits treble from rears). You may want to get the things you need and wait for a mod day when someone will be there that is familiar with how to wire it up. If you can wait until later this spring, I may be able to do it. I just got into a new house this week, and am itching to get a mod day going when the place is cleaned up.
