I'd actually like to see the flight plan entry in SV be a little more user-friendly. It seems as if there are an awful lot of machinations to add waypoints. Not at the hangar at the moment, but IIRC, it requires several steps just to enter an airport or VOR or whatever...FPL Menu, insert, dial up the waypoint, insert, confirmation, etc.
Not that Garmin has the perfect answer, but it's much easier on my 430W...a repeated series of entering waypoint id, then "enter", and repeat.
Just a thought...it's cumbersome to do in SV, but that may be a consequence of the overall UI.
Granted, once we upgrade to V10, and then "crossfill" (I know it's not a true crossfill), that should solve a lot of it...
Anyway, just a nit. Keep up the great work!
