You can’t, but as of July 1//24 it was supposed to be no longer possible to post to Facebook or Twitter., only to Mapshare. Garmin finally listened and discontinued posting to both. So I guess now we wait for months for a software update to remove them from the contacts list, message list and apps. and devices. Software updates are becoming a very rare event. Check the link below.
We sincerely appreciate you reaching out to voice your concerns about not being able to delete or de-prioritize the social media options when selecting your contacts. At this time there is no way to remove and/or move down the Facebook, MapShare or Twitter options.
We're always looking for ways to improve our products, apps, etc. We have passed along the suggestion to the appropriate team that being able to remove those options or move them to the bottom on the list would be beneficial!
