No problem Steve...glad I could help. And it might be that some of the XM units scroll text, especially the portable ones. I have no idea since the only one I have used is built in my car. But the GM ones from 2007 and prior definitely don't. Their displays are basically one screen off of a touch driven menu system. Maybe that is part of the reason. Mine is also a GPS.
I would think from a software point of view that more frequent updates to the screen (like for scrolling) would require more CPU time and maybe that is at a premium due to the GPS having to update.
