My (recently replaced) Garmin 520 has picked up a wonderful “quirk” which means it connects to the PM , but can’t/won’t calibrate the Stages PM - it errors and sets it to zero.
[An aside: Garmin say they can’t/won’t do anything and don’t guarantee their devices work with non-Garmin devices - great!]
Anyway, to get around this issue, before an outside ride I’ve been calibrating the PM using the Stages App on my iPhone, and then record my ride as usual with my Garmin.
Does my Garmin record my ride using the latest calibration data even though that calibration was on a different device [Stages App]?
Or does it only record data according to the last calibration on that exact device [the Garmin]?
