I just want to share an observation:

When the text on the gauge cluster only utilizes about half the display, you can go to disc 6 and scroll up to CD6-2 then CD6-3, and keep toggling between the both. It displays what I assume to be software versions, like [CAR 1.0] [iPOD 2.2] etc. Then when I go back to the iPod, CD5-1, then to CD1, the text uses the entire display.
