Pulling the radio is not hard - remove the ashtray (push down the little spring clip till it falls out) and the cover on the top of the dash for the defroster duct (pull it our, or genly pry it). This will reveal 3 screws - 1 behind the ashtray, and two underneath the cover. Remove them, and give the center bezel a good quick tug - it'll come right out. After that - two more screws will be holding in the radio. remove them and pull it out.
Otherwise - you could try reaching behind it via the glovebox (remove the door obviously)
