CD changer, FM modulated

Just got done replacing coils, plugs, valve cover gasket, air filter. Car runs SO MUCH better. Now I want to brighten up the inside with a CD changer and 4 new window regulators. Where do I start to pull the factory head unit out to get to the antennae?

Remove the ashtray. Then, remove the trim around the ashtray (pry from the top corners. It tips out). After that, pull out the center vent (prys straight out...no tipping.) By that point, you should be able to figure it for yourself.
