Same here - likely just a security patch, software version didn't change, subwoofer control didn't appear, etc. My MMI has shut down twice while driving in the last month, but they only wanted to apply this patch and hard reset to try to "fix" it. Maybe at the next service I'll try again for an actual software/version update.
