i dont have a link to directions, but ive done it a couple times myself, so here goes:
1. empty most if not all items out of glove compartment, make sure its not too heavy
2. at base of glove compartment, where it hinges, there are 2 bolts, one on either side, holding it in. leave glove compartment latched closed and take those out
3. remove glove compartment by unlatching it like you would normally open it
4. you can now see the piece of plastic molding(moulding?) covering the stereo opening. unscrew all the screws holding it.
5. once all the screws are out, gently pop out all the plastic snaps holding the plastic in place and remove it
6. there you go, you can now remove the stereo head unit by pulling it straight out
HTH, and let me know if you want more detailed instructions
