To remove the stereo you have to take off the trim piece that covers it
first. there are 2 screws at the top, just over the stereo. if you feel
along there you can feel where they are. Then you have to remove the boot
around the shifter. it just pops out with a little work (at least on the
manual transmission - auto might be harder). Then there are 4 more screws
under the boot. With those removed the whole front plate should come off
with a little work and careful prying.

Then there are 2 metal vertical support pieces visable. Unscrew these and
the whole stereo, as well as lighter and ashtray should come out as a
unit. Unplug the wiring harness and the stereo comes free.

If you need more instructions and pictures, I found the hanes guide to be
helpful.

Hope this helps. It is really quite easy to do if you are careful and take
you time.
