Bulkhead Speaker? - rundlc - 09-15-2021

Does anyone know what this thingy is??  I need to hard mount my Garmin and this seems like a great spot to do it. I'm thinking its some kind of speaker but not sure to what? Back up camera?  

TIA

It looks like it could be a microphone for hands-free Bluetooth.

Looks like a remote temperature sensor used by Dometic (DuoTherm) mulri-zone temperature controllers. The main controller senses one zone but the other zones each have their own remote sensor. I have one like it on the bedroom wall in my Teton Reliance. It is for the second zone in my system.
