Direction Indicator on Rear View Mirror
 

I bought a 2018 Accord, EX-L, with Navi, in November 2017. I am virtually certain that the rear-view mirror had a directional indicator and that it stopped working several weeks ago. The navigation screen of course gives you the direction as well when Navi is on. I've asked Honda after the dealership has told me this feature didn't exist. The agent from their on-line chat seemed to indicate the manual said something about a compass, but my wife and I searched it high and low and could find nothing about this feature being on a mirror. I'm waiting for a technician to call me back, because what the agent saw didn't specifically refer to this feature. I'm going to check my sticker to see if this is mentioned. Thanks for any guidance you can offer.
