Pry the upper dash vent panel off, use a plastic tool if you have. Radio is held in with a couple screws deep in the dash, need long Phillips to remove. Heater controls themselves are a pita if you have manual controls. I've only removed them on cars that didn't need to go back together but I recall it being easier to just unhook the cables at the heater box than to try and mess with removing them from the control panel with no room to work.
