My brother has a 06 cobalt with a stock stereo and wants to change it to an aftermarket headunit. He still wants to use his steering controls though. I have googled a little bit and have read a million different answers. What harness do i need and do i need a special module to keep the steering controls?
Also we havent chosen headunit yet.
Thanks!

 

I don't think it will work, but I am in for figuring it out.

 

ask riceburner.
