I did the swap a few years back when I still had my Gen 1. It's fairly involved and kinda expensive, but good luck.
This DIY is to backwards integrate a 2013 Cruze MyLink touchscreen system into a 2011 or 2012 Cruze. What you get- You get voice activated indexing on your USB, your touchscreen. You also get stitcher and Pandora streaming. I did not hook up the rear view camera, so can not tell you if that...
