Answer:
There’s a small, triangle-shaped piece of plastic on the inside of the door, opposite where the mirror attaches. There may be a small tweeter speaker inside.
With the door open, gently pry that triangle off and loosen the 3 screws - these hold the mirror on.
Have someone hold the mirror or prop it up so it doesn't fall and bang against your door once it's loose.
There should be a wiring harness connector. To release, press the plastic tab on the connector - pull to separate the plugs and remove the mirror.
Installation is the reverse.
