Thanks for the suggestions, Bert and I will have a look. The thing I find fascinating about the Phenom is the checklists which I follow to the letter when starting her up and it is so satisfying to find it becoming more natural as I become aware of the flow in the procedure.
I also have the Carenado Premier 1A which I love but it has a problem following Vor and Glideslope ( finding myself shouting back at the repetitive "GS" warning, " I know, I know it's not my fault!) although the GPS works wonderfully well, with regards to FMS Nav, Vnav and landing.
I have just been informed to assign a button or key to the GPS/Nav toggle switch. So off to do just that.
