I know this may be a really silly question but I haven't dug around to figure it out. On the stock radio how do I make song titles scroll so that I can view the full title.

 

You see on the right side of the headunit there's a button that reads "DISP"? Push and hold onto it until the display changes from track number and time to the title of the song. Don't expect it to scroll the entire title for you. You'll have to push the "DISP" button to view it. Only radio stations will scroll automatically.
