Hey Snakeyes
Thanks again for you help. I had the XM tuner (GEX-P920XM) put in last Friday. I am so glad. Before the switch, every time I turned Sirius on I felt like I was getting ripped off. I really hated it. This is much much better. Channel Name, Artist name, Song title, Station graphic and # all displayed correct. 
Even the presets are better. With Sirius no info is displayed, just preset 1...etc. With XM the station # and name are displayed in the presets.
The online listening is better with XM too. With XM you can see a list of stations with songs currently playing.
To make the whole deal better. I got the $77/yr and no activation fee deal Fat Tony talked about in his post.

I didn't use any codes, just told them I wanted the $77 deal I saw on the internet and they said no problem.
This was a really great move.
