I am desparately trying to import a course to my 310 XT without success.
(with the Forerunner 305 and the Training Center everything was easy, the ANT and the new Connect are creating many obstacles).
After converting the course I want to import via gpsies to .gpx or .tcx I am trying to upload it to connect but get an "undefined" message - See attached image. Changing formats or even limiting the points on gpsies does not help.
Opening the .gpx file in google earth works so this is obviously not a corrupted file.
