so it does work on a 03 model?
There is a link to a thread on the .com forum in the first post in this thread. Did you read that?

NOTE: The factory headunit's firmware revision must be 9.55 or greater. The unit will not work on earlier firmware revisions or with 9.81 or 10.01. To find out which revision your Mazda RX-8 has, make sure the radio (FM) is turned on, then press and hold "TEXT." Then, also press and hold "1" at the same time for a few more seconds. The LCD should then report your firmware version.
In fact that is a direct quote from the manufacturers website

If you are referring to the fact they talk about "NOTE for 2004-2005 Mazda RX-8" and dont mention 2003, its because the 2003 built cars are technically MY04.
