kind of a late reply
Big differences I notice are that the Canadian Models are all 2012's and the Deutsch models are 2011. Aside from what you have already pointed out, the Nav. is now touch screen, there are the Buick trademark port "vents" in the hood, the front Euro license plate cover is now a solid 1 pc bumper cover,the fire extinguisher elastic band/holder in the trunk went away, there is a chrome trim door handle cover for ALL 4 doors now and the cup holders get a rubberized insert. Those are just what I could tell were the visible details. Drove a loaner Canadian model while mine was at the dealer over the weekend, so I was paying close attention as to what the changes were. SO glad I have the German version!
