you can press open with one hand/body, whilst unfastening the screws with
the other hand. or, get a friend to help. I was able to remove my mirrors
by myself. remove mirror shell first, then remove mirror assembly from door.

but you may not need to remove the mirror assembly from the door, if you're
only looking to replace the mirror cover and/or to swap out the mirror itself.

if....you're having to rewire for the LED array, then yeah....it possible that you
need to fiddle with the wiring connectors as they pass through into the door.
