Updated to 5.8.1.49.30
I updated on Dec 18 to 5.8 1.49.30. It took about 45 minutes. There was a notice that the update was not successful. After restarting the touchscreen , there was a notice to contact service. I was told there is a bug that leaves a door handle nonfunctioning on some vehicles. Sure enough, my right front handle won't extend at all. It is scheduled for repair.
