Its a piece of cake, open the tape player flap and (gently but purposefully ) yank straight out, then work your way up and all the clips will release the cover... cut a cable tie, remove two harnesses then 6 screws and finally 10 harnesses and it will be sitting in your lap.
You don't need to cut the cable tie. Just put a 5 mm socket over the retainer and it will release the clip holding the cable tie. You can then reuse the retainer when you reassemble. The black felt covered harness is very delicate so be careful.
You should already have the SAT cable prewire going to the rear seat in an FX, shouldn't you?
