ugh, I hate working on Honda Radios. I swear the purposely make them as hard as possible to remove.
Case in point, my friends 92' civic hatchback, had the radio screwed in with two screws on a back metal lip of the radio, it was impossible to find an adapter bracket, so he ended up having to "wedge" it in there.
On my brothers 97' Accord, getting the radio out required haveing to remove the entire center console (from inbetween the front seats), and then dismanteling the center dash.
