Trying to upload a new course from connect phone (bluetooth) while a course is still active on the garmin edge 1000 is not possible.
I normally have a multi day course going when biking, and keep the session active during the days of traveling
as tomorrow we want to change courses, i created a new one to upload to the edge. I tried many times reconnecting with my phone
while upoading the new course to my fenix worked while there must be something with the edge.
finally i closed the session and saved my training and instantly the new course was loaded to the edge.
sad enough i now close the training so i need to restart a new session tomorrow
