scott, a quick review shows everything is working fine
the mute/unmute commands are being processed
there is no problem in software here
i would suspect signal strength, then suspect the tuner
please do what i say....
once it fails, STOP USING RR, and USE XMID!!!!!!!
also after 4:44, and u said u got no audio, u didnt do what i said, go to mp3, then back to xm... (and that should be done after xm is running)
and u didnt do what i said too, turn off XM CACHE!!!!
i cant help you, unless you follow instructions....
this at this point we need to go to IM... im on MSN... we can debug issue live
