Epix PRO 51mm drain

Pulse ox is off?

Connect and sync the watch with garmin express. Let's see if this helps. 

A couple things to try:

1. Make sure there isn't an app or activity running in the background. Even turning the watch off and back on won't end an in-progress app/activity that's running in the background. Press that Start button, and make sure it opens the activity list menu like normal, and doesn't go straight into an in-progress activity recording.
2. Disable any external sensors and headphones you may have added, see if that helps
3. Join the beta program, and install the next beta when it comes out (probably later this week, I'm guessing) and see if the firmware update resolves it.
4. Hard reset (factory reset) would be the last resort... personally I would rather wait for the beta firmware to come out and try that first, since a hard reset means you'll have to reconfigure everything on the watch from scratch.

Nothing of this help :/ also gps version is 0.00

In that case it sounds like your firmware got buggered up somehow, probably #3 or #4 are going to be the only solution - do a factory reset now, or wait until the next beta firmware release and see if that fixes it.

By factory reset U mean: on watch->settings-system->reset->erase activities and settings?

You could try the less nuclear option and just reset to default settings. However, if you have access to the beta software you could try to reload an earlier version of the software first. I think that might be the best chance of getting your GPS sorted. You might want to contact Garmin Support too.

Before you do that read this - copy your device drive  . You can copy your activity screen settings across so you dont have to redo them all.  (One day we will have backup and restore...we hope)
