Just installed my PCR xm. I bought it at Time Trax. It works perfect except for a nasty hum on recordings (also bleeds thru in I tunes) As it suggested in the troubleshooting section, I bought a ground loop isolator from Radio Shack. It worked great. It replaces the cable from the XM reciever to your sound card(Creative external Sound Blaster 24 live....kicks ass)
