I agree Fred! The XM satellite has better quality sound! But do you loose the single sometimes or does that not effect it, like tunnels, bridges, in town buildings? And please list here or pm what all I need to install this system with better quality sound! Thx Dan

Basically the ladder of improving sound quality goes something like this, starting with the worse:
WX
AM
FM
XM (Depends on how much compression at the time. I've heard some XM sound worse than FM)
CD-DVD / Bluetooth / Wired USB AUX (depends on the format and bitrate used when storing the files)
I suggest reading the thread about this install, there is a lot of good information there.

Depending on your individual wants and desires you may want to change some of the components. I had no desire to plug anything else in or maintain XM functionality. But did want to be able to get the most volume.
