I have the audionet card installed on my demo system (AMS-AIP), works well, I have not set up the xm portion of it, simple to use, I do like you can set up playlists from a browser. Also you can have audio files on a memory card loaded into the unit for door chimes or event messages which again I haven't done :)

You can listen to the stations and decide if they are worthy of being to your custom play lists, you can have a bunch, like his & hers lists etc. Selection is like the tunein radio app on the iphone (which is my fav) Also if there's a station not on the list you can add it,
