This is my first post here in this helpful forum.
In a couple of months I will own a RV10 with G3X touch and a GNC255 as a radio navigation source.
I think it would be a nice feature if when I'd select an approach in the G3X, for example, ILS one, the system automatically changes the nav frequency on the GNC255 and loads the approach profile on G3X system as if it were linked into a GTN.
This would make lesser the workload and at the same time a more intuitive procedure.
Excuse me if this feature already exists.
The profile view of airspace it's a very good idea to adopt on G3X.
