That rings a bell...
I haven't done one of those model Civics, but yeah that is the way late model Hondas come apart.
It's really hard to remember how to pull them apart when all you've got to play with is a picture on the net.
If they're anything like late model accords there should be a couple of screws up through the back of a bracket, and then the pocket and head unit will slide out as one.
