It seems that everything that can be got to work correctly, has been fixed. there are stilla few functions that the Asobo kernel will not support (ie OBS), but soomer or later Asobo will need to fix that. so its just a matter of waiting on Asobo.
As it is, it is now a pretty true representation of the RW GNS530 (plus a few extras, like weather radar !!).
Being able to use its FP database library, and load FPs into it while flying (ie from apps like LNM), makes it a real pleasure to use.
