S580 (Canada) overhead speaker no sound?
I have a2023 S580(Canada ), A little question about the overhead speaker ! Between two pieces of the sunroof, there has a speaker, its looks like a burmester speaker, but its no sounds!? I have a package called premium rear seating plus package, one of the option is "Rear-cabin MBUX Interior Assistant" , I noticed that if s580 have this package , there will have one overhead speaker, if s5820 don't have this package, then no overhead speaker. I don't know this is a real speaker or just a design? Because in my car, this speaker doesn't work, which means no sound. But the ambient light is working. By the way, I don't have Burmester High-End 4D Surround Sound system.
Thanks guys ! ! !




I hope its not a design,I will go to dealership. Thanks

-Any S with no high end audio (811) and no rear interior assist (78B) doesn't have any speaker on the roof.
-Any S with both 811 and 78B (for US Market this can pretty much only be 2022+) has the speaker and the gesture unit in it both active. For most if not all 2022+ S Classes that have the high end audio but no executive line/rear seat package will still have rear inereior assist as a standalone option so it's still active, unsure about Canada.
-For 2021s with high end audio, as 78B was not yet introduced, they must have the space for the rear inteior assist but it must just not have any hardwear/not be active. It's possible some 2022+ S580 luxury line/AMG line with 811 have no 78B and therefore also have this setup.
-For 2022s with executive line/rear seat package which includes 78B (2021s didn't, at least for the US), they'll have the extra speaker in the roof that houses the rear gesture camera but the speaker won't be hooked up to anything and won't work. This is where OP exists.
I'm pretty sure that's all correct but feel free to add your own evidence or experience.

Hi,thanks for the help!So my 2023 s580 have executive rear package,which include rear mbux assistant,but no 4d,it means the speaker is only a design for camera and no sound come out,right?




This car has the high end audio but no 78B, it's fully filled in with a circle in the speaker.
This one has 78B but no 811, it has the cutout. My assumption is 78B and 811 will have the same design, though I have had trouble confirming.
And yes, it seems as though without 811, that speaker does not produce sound. Best way to test that, though, is to listen close. But I can't imagine it gives sound given that a car with no 811 or 78B will have no speaker there at all.
