Anyone know a fix for this problem: Watch says Im at like 35,000 feet and I gain like 18,000 feet even on a 3 mile run…

Mine is doing the same. There’s a way to clean out the opening on the back that’s suppose to help. I haven’t done it myself yet.

It’s jacked. Hardware and not firmware despite what some thought at first. I’m on my 3rd one and Garmin said the fix each time was to replace the unit with a refurb.
Just my experience. Good luck!

Had the same issue long ago, in the back of the watch in the lower right there is a small hole, I cleaned it with an old toothbrush, I took out some kind of white sand, looked like sun screen, after that no more issues.

How do you know that without the watch? I had two garmin said that about and sent back. Then had it happen a couple of times after I knew about cleaning, it worked everytime since…So how do you know for sure?

There are 2 holes actually. Clean em both! Soapy water and toothbrush. Fixes it right up.

I can confirm that soapy water and a gentle cleaning with a sonicare toothbrush worked for my 910.

the one from CarbonMan. It is exactly the process Garmin made me do over the phone.

Very good question. I have the luxury of living near Garmin HQ so I am able to go directly to their on-site help desk folks. They can boot it into a diagnostics mode and they can figure it out that way. Plus I was also running the Garmin marathon when one of the times it happened (starts/ends at Garmin HQ) and was able to show a Garmin tech person at the end of the race. Also, I swim with mine in a pool regularly which helps keep the hole clean.

Oh, sorry. I don’t know what other guy you are referring to. Maybe I didn’t say it well but mine failed 3 times and each time Garmin said it was the hardware problem. Hope that helps.
