I have XM for a few years. I don't have any problems with audio quality. Reception can go mute under bridges, tunnels, or other large obstacles, but that's that. Otherwise, is the only thing that works on mountains, remote roads, or anywhere really. For the sales, I call them every ~5 months, say I will pay $25+tax for 5 months or something like that, I set the next calendar event.
