I thought I would start this topic as a means of discussing the fact that north is always facing up in 2D mode. Besides the persistent boxes (fixed) and the long boot time, I think this is the next biggest complaint about the navigation section.
Today, I was playing around with the zoom in 3D mode and realized that if you bring up the pan & scan controls, you can "tilt" the display so you're looking straight down. That effectively makes it a 2D view, but the map continues to track with the direction of travel. The only issue is that it reverts back to the default view as soon as you press the map button, but I think there's a way around that using pioneer.ini.
I'll post more information as I have it.
