Hi,
Since the latest update to Garmin Express that ran on my PC today I now get an error when I try and upload a course to my 310 XT.
I thought it may be the new course I created, but I get the same error when I try send courses that successfully uploaded in the past.
My watch is only on 18% memory used.
Garmin Express opens automatically when I select Send to Device and the sync starts, my watch goes into Data Transfer mode, then a message comes up on Garmin Express
"Some files could not be sent to device(Transfer Error)".
The course is a scouting route I ran with the watch then edited on Garmin Connect and would like to reload to the watch for an up coming race.
