About the INU, I don't know if it's intended, but allways I check "WP 00" LAT LONG at VEI mode, is different to LAT LONG data obtained at F10 view, like actual manual we got (and because I'm not happy with the coordinates), I correct them, and sometimes I imput some of them they has changed some arc-seconds... like this:
My imput -> N42.10.004 -> INS Key
Displayed -> N42.10.005
I don't know if I doing something wrong or this is correct behaviour...
PS: I have INU need to aling allways and Giro Drift enables options ON.
Thanks for your work!!
