Stock headunit

Does anyone know where the screws are to take off my stock headunit? They're usually under the dash, but I can't seem to find mine.
If anyone knows, please help me out.
btw my car is a '01 Prelude.

i know on my rex, there were two screws behind the deck attached to a peice of metal holding it in, after that it just slid out.

yeah, well on my 4th gen, there were screws underneath the dash, but there seems to be no screws on my 5th gen.
