It should slide straight out (horizontally) 
there are 2 plastic "tracks" it is held in with, no screws. 
grasp at both sides, and with plenty of swearing, it should come out. 
sometimes the top of it gets caught behind the bottom part of the metal dash,
and you'll have to pull it down, the same time as you're pulling it out, if that
happens.

Remember, it is plastic, and if forced in cold weather, it will break.
