Trying to understand how the auto-dimming Rearview mirror works on my 2016 RDX Advance. It looks just like the rear view mirror in my 2013 Accord EXL without a power button. My Accord mirror has a green light when it is powered on. There doesn't seem to be any power button and no lights to show me it's working on the RDX. Any insight?

It detects light coming in from the front and rear and turns itself on and off accordingly. Try shining a bright flashlight into it at night and see if it changes the light.

Though I've made an odd discovery: my sister's '15 RDX Tech has a green light in the mirror that comes on at night. My '16 RDX Advance has an identical looking mirror casing, but no green light comes on. Weird...

That's exactly what I'm curious about. It seems to be the exact same casing but there's no green light.

With 2015 it's on all the time or you have to turn it off. 2016 has auto feature.
