I have an Edge 130 and a Fenix 5X. The Physio True Up feature doesn't quite work in that the Recovery Advisor data doesn't flow from the Edge 130 to the Fenix 5X. It flows from the Fenix 5X to the Edge 130 though. All the rest of the data flow.
According to everything I can find on the Garmin sites, both devices support Physio True Up. And both have settings to enable it. And it seems to (almost) work. But today when I chatted with Garmin Support, I was told that neither device is compatible.
Here's what I think is really true: The functionality has a bug or is not yet fully built out. Not that they aren't compatible.
Anyone out there have a definitive answer?
Someone from Garmin maybe?
