My 2018 Canadian Touring model has the auto-dimming inside rearview mirror, but I can’t tell if it’s actually working. My last car, an Acura TL had a similar mirror and there was a green power light on it, as well as a button on the bottom to switch it on or off. The Pilot’s mirror has two small circular/ oval objects on the bottom of the frame, but neither lights up. I expect that one of them is a light sensor, and the other should be an LED. What does your Pilot’s mirror look like and behave like?
