It is finally available!
First observations:
1) The chart of the Lake Michigan is pretty large scale and I cannot zoom in to see the particular harbor (entrance). I am sure that can be fixed by uploading specific charts, I just did not figure out how (Lake Michigan uploaded automatically).
2) I did not figure out how to sync the Routes and Waypoints with MacENC yet, but I've seen the functionality is there.
3) I would like my iPhone to be able to tell my MacENC where I am.
