Go to Garmin Connect. Click on your user name, in the top right corner. A menu will drop down, which has the option for Create new group. This page: http://connect.garmin.com/settings/groups
This is an old thread, but I don't see the option to start a new group in that pull-down menu. All I see are the group's I am already in. Anyone know a way to create a new one?
When you click Groups in 3bar menu you get to a Groups page that has 'Create a group' option. Also in dashboard if you have added the Groups widget you can click the + icon there to start adding a new group. Both paths will take you to the same group adding dialog.
Thank you for all the suggestions. I finally realized that the problem might be trying to do it on my iPad. My desktop shows those buttons and links without a problem. The mobile app is somewhat limited for some actions. Thank you again for your quick responses.
