04 Rx-8 Sirius
 

On the 04 models are they Sirius Compatable? It doesnt have the sat button but i was just wondering

If you mean the factory sat radio option, I believe the answer is no. You have to get a separate sat radio receiver and feed the signal into the head unit with a PIE adapter or AuxMod.

yeah thats what i kind of thought to but wasnt sure.. wish i could have got at least an 05 for that reason.. o well.. not that big of a deal.

Well, if that's all what you're missing from a '05, you could always get a '05 head unit with the sat button.
However I think it's much better to get an aftermarket sat receiver for a '04. More cost-effective for sure.

yeah being that i used to be an installer i can do whatever i really want, its just a matter of what look i want, and i really like the factory look, and need all the space i can get so its just depends on what i want, could do the 05 switch thanks!
