I create a course and then send it to my device. It says that it sent successfully but when I go into my Garmin and tap "Courses", it say none found. How do I get the courses to load?
Are you using Internet Explorer? If so, you'll need to add *.garmin.com to the list of trusted sites.
In IE go to Tools > Internet Options > Security > Trusted Sites > Sites. Uncheck "require server verification." Enter *.garmin.com, click Add, click OK. Close IE. Restart IE.
