Need to remove the rear view mirror to install my radar detector display inside it. No obvious hardware to remove after I took off the trim. One 5 pin connector, no screws or indications of how to pull it down.
Remove the plastic cover from behind it, unplug the connector, then rotate the mirror base to unlock (sorry, I don't remember which way). Easiest is to grab the whole mirror and turn, rather than hold onto the base.
