- add contacts and choose recipients for "Check-In" messages at https://explore.garmin.com/Messages
- on phone, install Garmin Explore app (The Garmin Messenger app allows you to send/receive messages when paired, but doesn't allow configuration)
- on phone, turn on bluetooth and "allow new connections" if necessary
- if not first time using InReach Mini, go to Menu -> Settings -> Phone -> pair (enters Pairning mode); then in Garmin Explore app, go to devices tab, click through screens to connect to your device
- Messaging settings will now sync between website and device, can take a couple minutes
- Check on handheld: menu, check in -> should see your check in presets. Selecting one shows contact list and message content.
Note: the Garmin Explore phone app is the only way to sync messages from the website to the handheld device, and the website is the only way to set up the message settings. Various instructions mention Garmin Messenger App, but at least for iPhone as of July 2024 it neither syncs nor configures message settings.
Things that don't work:
- "sync" option on explore.garmin.com: not implemented?
- Garmin Messenger App: does not provide syncinc capability
- Garmin Sync Desktop App: outdated?
- Garmin Connect Desktop app: no functionality
also note that even if your device is listed in the Garmin Explore app, might not actually be connected. Green dot when connected.
