A lot of angst is vented on the site about what to do when one of the numerous electrical and software goodies goes on the fritz after and update or seemingly out of the blue.
The first thing......Don't PANIC! As one of the first owners of a 580 I have been through most of them (probably all). I have never had to take my car in for a fault EVER. If you have something to do, go and do it. The car is always driveable since the drivetrain system is independent from MBUX. If you have time, get out of the car, lock it, and walk away. Wait 30 min or so. Unlock it and drive away! If that system "reboot" did not work, lock it when you get home and leave it overnight. It seems to work itself out overnight essentially every time.

 

You can also reboot MBUX - by holding down the 'power' (1/0) button on the console, until you hear a chime. This takes less than a minute.

 

In my experience, troubleshooting issues with my EQS technology has been similar to resolving computer problems. Often, a simple restart will resolve minor glitches and malfunctions. While there have been some more complex issues that required professional intervention, the majority of issues were quickly resolved with at-home solutions, much like the methods you have described.

 

Sledgehammer works for all sorts of computer problems.

 

The first thing I learned how to do is reboot the system and unplugging it from the power source if needed.
