I have XM in my suv, it came with it too, and we ended up keeping it after the trial ran out...But my husband has serius in his work truck, and its WAY better! I know that they have merged and all that, but on Serius, you can pause, record and relisten to a song over and over if you want....the stations are the same but I'm so envious of his ability to do that, makes the XM more like any old radio station...
Just my two cents
