Yeah, the 05 si has that crazy shifter on the console. i dont think that the dash is the same. Im sure it still has the double din opening though, so you should be able to find the same trim piece that DLe and myself used, but for your Si dash. It costs like 15 bucks. Once you have that in hand, you should be able to fit the 7" monitor in the factory opening (double DIN) with a lot of cutting (of the bezel around the monitor).
