All of the Serial GPS\NAV sources have issues with the CRS.
The CRS is showing to the ARINC CRS instead of to the selected serial.

i don't understand the VOR display and CRS either, it is getting it from my G430W, it seems to always show the CRS to, I can't seem to adjust it while it is in bearing mode, only if it is the primary PFD source.
Ok.... Found the source for the problem on this too.
The issue was that the second display did not have the serial inputs connected to it.
As a result, during powerup the second display would boot first and will somehow take priority over the CRS (not distance).
Bottom line. Wiring to the second display changes the behavior of the main display too...
