how to sort out your elevation garmin it was measures 0 but I running up hill

I'm having an issue with elevation on my 2X, I've tried to calibrate and also clean the port but it's still occuring. Checking back it seems to have been slightly off since around early March, I contacted Garmin support chat and they said my activities…

Hi

when i create a course in explore i dont get elevation data when i follow the course on my instinct. When i do it in garmin connect i get elevation data. Whats the point doing it in explore? It is much easier in explore but not worth it without data…

Been out running with friends tonight, there elevation shows 68m, mine 438 

Why is this so wrong 

Since a few months the elevation of recorded activities on my Forerunner 255 is often way off (and I think that messes up other metrics as well). I often record 100m of climbing and 150 meter descending on a 5k run on totally flat terrain.

I don't think…

I have a Garmin Forerunner 920XT. I live in a very flat area But it shows as my elevation over 20,000 feet. How do I reset this?

Why don't Garmin reports have elevation gain and grade adjusted pace?

RESOLVED: 

It was a hardware issue. Watch exchanged under warranty, new watch arrived on Monday. 2 runs and a walk and all the stats are perfect! Power within expected ranges (based on FR955 and similar routes and effort), temperature seems reasonable…
