Well it seems like the 02' civic si is totally different than it's older generation models. With the older models, all you did was slide out the small compartment on the side of the HU and everything just came apart. I haven't worked on a 02' si yet but from looking at the pics, it looks like the dash is a 2-piece dash. If you look where the radio and the shifter is, there's a separation. I would have to guess you gotta pop off the entire top portion of the dash but inserting a thin screwdriver. I would start off at the top where the a/c vent. Hey is there a separate piece right between the 2 a/c vents? If it's anything like the 98-02' accords, there's a screw securing the dash. Well hope whatever i wrote helps. G' luck!
