2003 Civic Cd Install Help

First you have to pop off the lower dash panel (where the cigarette lighter is).  Usually it's just held in by some spring clips, but sometimes it is also held in by screws, some of which can only be accessed by opening the glovebox (right side) and the section of the dash panel beneath the streering column (left side).

Once you have that panel removed you'll be able to get to the underside of the radio. There should be two silver phillips hex head screws that go into the bottom of the radio housing bracket.  Remove those and that whole section of the dash (including the climate controls) will all pop out--it's just held in with some spring clips at that point.

You may have to remove the big climate control assembly from the back of that center section of the dash, in order to be able to unscrew the factory radio from its metal mounting bracket.  Fortunately the dash kit is a piece of cake to pop in there.  Just make sure you remember to put back that climate control assembly before you install the DIN cage for your new stereo.
