Not sure if this is a bug or just not possible.
I find the map view in Garmin connect restrictive when viewing and planing routes (via Courses).
Is there a way to view this in full screen? not just a letterbox type of layout?
Cheers
Been raised before, currently it's not possible. You could use Basecamp instead.
Also try posting your suggestion here http://www8.garmin.com/contactUs/ideas/
For mapping, you might want to consider Ride With GPS, which supports waypoints. And full-screen maps....
