These are things that could cause your device not to accept the course:
When naming courses, keep in mind that most devices have a limit where they only look at the first 15 characters in the name of a course. If there are multiple courses where the first 15 characters are the same, the device will think they are the same course. To work around this limitation, make sure the names vary within the first 15 characters.
Most compatible Garmin devices have a limit of 100 courses. If you are near this limit, or have many long courses, try deleting any you no longer need. Refer to your owner's manual for steps to delete courses from your device.
NOTE: Some models have a smaller limit, refer to your device specs on garmin.com.
