Have a LiveTrack compatible Garmin device. The following list comprises Garmin products manufactured since 2018. Some older models may also include this feature. To confirm, refer to your owner's manual.
The Garmin device must be paired and connected to the Garmin Connect app on your phone to use LiveTrack.
The app must be open or running in the background on iOS phones. For further details see: ( What Features Stop Working When the Garmin Connect App Is Closed on iOS Devices?)
The paired phone must be with you during your LiveTrack activity.
The phone must have a cellular signal when using LiveTrack.
Quality of signal can affect the performance of the feature and result in degraded performance (e.g., a weak signal, older generation network such as 3G vs 4G or LTE)
LiveTrack must be set up in the Garmin Connect app before first use.
NOTE: The Forerunner 945 LTE does not require a paired phone with a cellular signal to use LiveTrack when it has an active LTE subscription and an LTE signal. Your watch will indicate LiveTrack Ready when accessing an activity profile which means it is ready to start LiveTrack when you begin your activity.
