Sounds like I will have to try a new route planner & hope I can drag & drop into my Edge 200
The new 200 is drag and drop.
Create your route on RWGPS and save it (call it a name)
view your route.
On the top right hand side select Export
Choose the type of course, TCX or GPX (i used TCX on my 205)
The TCX file will auto download, normaly to your downloads folder.
I copy and paste this (you don't have to) to a TCX folder just for backup
With your edge plugged in via the usb go to you downloads folder, find the file and copy it as normal
Go to your computer, find garmin and open it, open the "new files" folder and paste in the file
When you turn on the garmin it will convert it into a course.
