Southern,
There are a few other changes and the paddle shifter is available but only with the summer tire package. Take a look at:
http://eogld.ecomm.gm.com/NASApp/dom...1&divisionID=5 and choose print book (it goes to your screen and not your printer) and choose CTS and the changes are highlighted in red. There are not many and it is hard to tell from the image in the guide but the new nav control panel looks like it has two disc slots. It may be the picture but it doesn't look terribly attractive (the control section) compared to the current system.
