Well, I've checked and my 2000 Xterra has the old style button for the mirror

But after reading some info on the donnelye site I gather that one could heat up the button on the windshield to soften the adhesive and then use maybe dental floss to remove the button.

Then maybe one could order a new style button from Nissan and remount it with the proper adhesive.

What does anybody think of this?
