I noticed the other day my 920 suddenly stopped giving elevation data for sessions. Today I see that it thinks my house is at 68**m; anyone else had these woes and fixed it? Google fu tells me this was common a few years back, and people got new units i.e. not an easy fix? At the moment, the watch also isn't recording any elevation stats in activities; I assume it's related.

Make sure any holes arent gummed up with skin and other yeuchy stuff which would upset the pressure sensor ?

DCR has a post on this, I think for the older 910 or 310. Upshot is warm soapy water and an old toothbrush into the altimeter opening. If that doesn't work, Garmin will do you a refurb unit for a fixed fee

Think of it as altitude training Very Happy

I used to get the same problem with my old Polar s625x - warm soapy water to clear any gunge out of the pressure sensor holes did the trick.

Clean and hope, friends resolved but went funny again 6m later. Blamed his on OW swim but clearly susceptible to any gunk.

Blocked port is common - my old 910 was fine as long as I swam regularly, as soon as I stopped it went up a mountain. Guess I need to swim more!

My new 935 got replaced under warranty when the altitude when skyward and the temperature hit boiling point. I wasn't climbing inside a volcano.

My 910 did this. Tried all the washing the ports and cleaning it out. Didn't fix it, then magically about a month later it started working again properly. Been fine ever since.
