Belkin F5X007 XM Radio Receiver

I purchased this on Amazon.com and was immediately impressed by the sound and weight of this unit. However, within a few days I found that I was only receiving static on the unit. Moved my RoadyXT back to my auto and same thing. The receiver showed that it was receiving a signal but no audio. I was finally told by Delphi (maker of the RoadyXT) that there have been a few problems with the Belkin F5X007 causing the XT to fry. I've had to send the RoadyXT back to Delphi for repair. They told me that Belkin or Delphi would be sending out a bracket that would solve the problem of frying XTs. Something about the plug-in interface not being exactly right. I sent the Belkin back to Amazon.
