Great news about the NAV system. I'm not surprised, since the Crossfire stereo is just a Harman Kardon TrafficPro system without the navigation functions. My guess / hope is that it will be easy for us '04 owners to upgrade to the new nav system.
For those who are curious, here's a link with a photo of the H/K Trafficpro with navigation (in black):
