XM Song Title/Artist Fixed Length/Does Not Scroll?

I have the in dash Nav system for my 07 Tahoe. I'm disappointed that either the Nav system does not support scrolling of names or can't handle song titles or artists that are greater than 20 (?) characters. The display seems it can definitely fit much more than it currently displays.

I guess there is nothing that can be done about this? I guess I'm used to my Sirius PNP unit that at least scrolls the artist or song title.

I believe that is an XM issue, and has nothing to do with the Nav system. There are other XM systems I've seen out there with the same issue...can't speak for the XM PNP though.
