Where Do Calendar Notifications on My Garmin Device Come From?

With various calendar apps available for users to choose from on their phone, you can learn more about how notifications are handled in the event you have more than one installed.

Android:

Android™ phone settings can vary by manufacturer however the notifications will display from whichever calendar is designated as the default. Users can generally check the app defaults setting on their phone to determine which calendar app is designated the default one.

iOS:

If you have an Apple® phone, any calendar added to the phone's Apple Calendar app will appear on the app even if you have hidden that calendar in the Calendar app.
