Bought a used truck several months ago and decided to have the sat radio turned on. I've heard it (possibly XM) in other cars and it sounded OK. but Sirus sound awful. some channels, especially the talk channels sound as bad as low bitrate cellphone audio. digital artifacts, swishy gargly audio. Even the music channels sound like low bitrate Mp3 or internet streams. Even youtube videos have better audio than what I've heard on sirius. As a matter of fact. The local 1000 watt AM oldies station in my town actually sounds better than the 60's channel on sirius. It sounds like listening to a bad mp3 file at the end of a water hose. Unfortunatly, I should have done my homework before sigining up. I'm locked in for a year. With a one year subscription you get a month for free. but I'm still out 12.95 a month for one year.
