I've replaced the right side mirror (2016 HR-V EX) and the mirror power adjusting and turn signal both work, no problem. I'm having trouble accessing the 'Hidden Menus' for my car. Google and Youtube show what buttons to push for accessing this menu on many different Hondas and supposedly the 2016 CR-V should be the same as my 2016 HR-V. It seems my Power, Menu, Brightness, Back, Eject, etc. buttons are in different locations from every video offered. Fortunately, I recalled accessing Honda Forum years ago for a 2009 CR-V I had and can't think of any better place for advice. I'll add a photo of the dash screen if needed.
