^ I just spent the last while browsing that thread and the links from it, it looks to be the way to go. My largest complaints with the car have been no aux, no bluetooth and no V8. I can fix two of those issues with an in-dash GPS and get rid of the Garmin on my windshield. It makes the car look a bit more modern too, which is always a plus.
Most reviews have stated that Kenwood has great GPS, terrible iPod support, Pioneer reviews have stated the polar opposite; great iPod support, bad navigation. That said, the AVIC-X920BT looks great and I'll be doing more reading on it when I get home. The 920 and 960 say they support Sirius XM via "optional tuners," so it'll be worth a look.
