Very interesting! A while back I experienced the same exact issue with my Caddy XTS Platinum: I had by Samsung S3 plugged into the USB behind the NAV screen (similar set up to the C7) and all of a sudden the screen went the way old TVs went when the tube was going. Once I pulled the Samsung out, the problem never occurred again in 7k plus miles. I am convinced it had to do with some sort of interference between the bluetooth phone and NAV.
