xmradio display

I have a 04 accord ex-v6 with/out navi. I had a couple of questions
about the xm radio. On other systems does it normally scroll, or can
i get it to do it on mine also. I noticed that some of the names of
the songs are to long to fit in the screen, but they still try to put
more in there like if the song has two names so it goes "first name
(second name)" and it will cutoff somewhere in the second name. Also I
noticed that below the display of cd1 cd2 and cd3 there is a ch and
category, and if I hold the disp button it switchs between the to but
didnt notice a difference in anything. does anybody know what this
does? also is there anything that is not in the manual that might be
of interest ways to do stuff with the radio. like if you hold the
xmradio button it acts like a blackout button. so nothing shows on the
display. thanks for all the responses in advance.

 

So nobody can help me with this?
