Thanks robot: A couple of extra tips from my experience

stuff tissues or foam or something in the holes below and to the side to catch the bolts if they fall. Leave it there permanently.

After you have the bolts out, hold the h/u up as you pull it out and tuck some of the towel you have over the console area up under the wiring

I believe the stripping of a bolt occurs mainly against the metal edge of the head unit bolt holes so support the h/u and visually align the holes carefully before inserting the bolt, then turn the bolt counterclockwise until you feel the thread match up, and then start turning clockwise gently. If it starts to bind, undo and start over. Keep holding the h/u in the hole alignment position until you have the bolt well in, then do the same with the next bolt etc. Go back and fully tighten.

If the h/u is going to be left hanging out, avoiding the volume control knob, put a thick magazine over the screen face to spread pressure on it from the gear knob or brake, then rest on the draped towel
