23 Escape with B&O system lost all sound (and how I eventually fixed it)

Faced a very similar situation to this a few days ago. Like chaimav I have a hybrid (so the 12V battery is hard to access) and the premium B&O sound system. Suddenly one afternoon the audio system just could not be turned on and the built-in nav was reporting GPS was broken, rebooting Sync did not help.

Came across this post and did pretty much everything exactly the same as chaimav except I just pulled out and opened the under-hood fuse box, then put it back a few minutes later. Had an issue actually pulling the fuse so it just stayed in the whole time. But disconnecting and reconnecting the box seemed to be enough to force the module to cold-boot and fix the audio / GPS issue.

That process did end up wiping my display settings for the instrument cluster so I had to reset that. But no need to redo radio presets or seat position etc.
