Overhead speakers not working after dealer service fuse or wiring issue?

[Glide&Seek6100]

I have a 2019 Aviator Black Label, and after having some electrical work done at the dealer, both sets of overhead speakers have stopped working. The rest of the Revel sound system sounds fantastic, but those ceiling speakers are totally silent. Could the technician have accidentally disconnected something, or is there a fuse I should look into? TIA

That's super frustrating, especially after a dealer visit!
It's definitely possible the tech accidentally unplugged a connector while tinkering on it, since there are a lot of wires going to that overhead console for the speakers, sunroof controls, etc.
I'd lean towards something simple like that before a fuse, since the rest of the system is working perfectly.
The overhead speakers are part of the main amp circuit, not usually on their own separate fuse.
Give your dealer and a call back and politely explain that you got this issue only after their work.
They should be able to get it sorted out pretty quickly under their repair warranty.
