I did a complete overhaul of my 04 3.0i's stereo system. I had not yet found this forum and ended up recreating the work above from the technical service manual diagram (in German no less). I can confirm that this is accurate for my particular trim level.

For reference I installed the following...

New Head unit (flip up touch screen option)
Included front facing and backup camera install
New 6.5" speakers front and back
New rear mid speakers (4")
Retained existing door mid speakers and tweeters
Powered using 2 1,000W mini class D amplifiers in the battery compartment where factory amplifier was located.

Audio volume and clarity are definitely improved over the factory setup. I now have Bluetooth, SD card, video, and many other modern conveniences available. I had to give up the steering wheel mounted controls (i planned to replace the wheel anyway so no big loss there).

I have some more tweaking to do for optimization of sound but I can now listen to whatever I like with the top down on the highway.
