I stuck with the stock HiFi upgrade that comes standard on 04 C4S models, figuring I could do something about the sound later.

I'm not much of a sound nut, and I think the Bose system I listened to in another car was good enough for me.

So anyone upgrade the Porsche HiFi (MOST bus) system to the Porsche Bose (MOST bus) system?

Easy, hard, screw it if you're going to the trouble might as well upgrade to something even better than the Bose for roughly the same cost/hassle?
