When I select Navigation on my Forerunner 965, the system moves back to Training and never displays my courses. This issue only started a few weeks ago. I've rebooted my watch with no luck. I've tried with my Forerunner 945, and this issue still exists. I can see my activities under courses on my iPhone with the Garmin Connect app. I use Garmin Connect to import my gpx file and then send the file/course to my device. This worked fine up until recently.
