yeah, waz (that IS a verb) out the ashtray with a bit of brute force, and remove the metal slider/bracket thing for it by unscrewing the short black screw in the middle. When you've got that out you then need to find the two silver screws positioned about 1 inch in from either side and about 1.5 inches back, they are sat in recessed bits. unscrew these two. The HU should now be loose, so reach around behind it and give it a push, et voila.
