Upgrade to 2004+ Bose radio -- Sirius

I was bummed to learn yesterday that my 2003 350Z is not satellite compatible. It has the AM/FM button. I was hoping to have Sirius added to the factory installed Bose radio. What do you guys think if I have the Bose radio swapped out with a 2004 or later Bose? I much prefer to have a clean built-in look (factory), rather than go with a third-party Sirius Kit with the radio in the visor, sunglass holder, etc. I would hope to find a "used" 2004+ Bose, possibly from someone in this forum who upgraded their radio to something else. I'm not technical, so I wouldnt be installing it myself...... Thoughts? Thanks.
