Navigation says "GPS is off" but its not?!

using the map or another activity works, so GPS is clearly turned on and working...

Try resetting the activity settings to factory default

already did that, still the same

Someone from Garmin care to reply? I have a very expensive wristwatch at the moment.

Garmin does not regularly reply here on the forums. You need to contact Garmin support directly via phone or chat.

2 things you can try: 

• hard reset the watch by long pressing the light button until it turns off
• Factory reset the watch 

Is there a Power Profile applied to that activity with GPS disabled?

Thanks. Power profile is set to normal. Hard reset didnt help either. Guess I'll try Garmin support directly then. They'll probably tell me to do factory reset anyway...

It only happens when I select "do course". Show map works funnily enough, including my correct current position displayed on the map.

Hi. I hope you still read this. I have EXACTLY the same problem at the moment. How did the story end? Could you fix it?
