Fiberoptic: What HD radio works best with the Guru? I noticed you had the MP3Car version in the photos, have you used any others with this setup and Centrafuse? I believe HD radio's that work best with Centrafuse are Visteon HDZ300 and Directed Electronics DMHD1000.

Also, it appears that Mitch's cable for HD radio uses a serial port which I believe these units do not have. How did you accomplish this, USB to serial cable? Is there trouble with a USB to serial going in and out of hibernation?
