Mazda 6 2004, 2005, or 2006 stereo in a Mazda 6 2003?

I need SIRIUS in my 2003 Mazda6... big time. I got the factory kit for my 2006 Tribute and its great, but I'd like to install a factory kit in my 2003 Mazda6, however as you all know, the 2003 doesn't have a SAT button. I have no problem swapping out the radio/buttons/ whatever else I need to get the factory SIRIUS rockin!

Please let me know what you guys think!

Thanks.
Anthony

The bezel has the same mounting points for all model years, so if you can rig up the wiring yourself, the 03 Instrument panel will accept the 06 radio.
