I have a Z1 in my '06. Everything works. Just be prepared for a surprise when you get it installed. I called around and got a few quotes which were all in the same ball park. However, when you show up, for every detail that you want to work (steering wheel controls, XM radio, iPod adapter, Onstar, camera, etc.) they keep pulling out the accessory cord adapters that have to plug into the unit to hook everything up. It starts to add up real fast!
