Recently I managed to drop my phone somewhere on the trail, and noticed it later. In the connect app, you can display the last known position of your garmin device, if it gets lost, but not the other way round. It would be nice to have such feature in the garmin device.
I was very happy to locate the phone since I activated live tracking (sent via e-mail to my wife), but I needed help from fellow riders to get the information from my wife.
