I completely agree with the preset and single line information items on your wish list. In fact, I came here trying to find a way to get more than one attribute (artist, song, etc.) to display at the same time on the Sirus screen and found this thread right off the bat.
I was hoping I missed something in the manual or perhaps you guys had found and posted some gem of an "undocumented" feature to get the additional information to display...
I just submitted a complaint/suggestion too (thanks for the link).
Has Pioneer issued any software/firmware updates for the D3 yet?
