  • For the record: 18.10 has fixed my issues. The elevation gain accuracy is just about where it was before things went haywire. I'm a trail runner and in the habit of entering the known starting point elevation right before the run. Pressure changes during the run do impact the accuracy but that is a known factor for me. 

    So thanks, Garmin and good luck to all of you who still have problems!

  • I have two garmin instinct one with firmware 17.5 and the other with 18.10 and a fenix 6. I did a comparison on a 50km bike ride and I noticed that the altimeter between version 17.50 and 18.10 varies little, about 10- 15 meters, the only thing that changes is the total ascent on the 17.50 firmware gave me 815m while on the 18.10 it gave 870m, while on the fenix 6 it gave 865m and the altitude varies little (about 5-7m), so very similar to the instinct firmware 18.10.

  • After automatic update to fw 18.10, GPS stopped working. I tried a hard reset and other advice from the Internet, but nothing helped. I left the watch for a few hours at the observation tower with a 360-degree view, but the GPS did not find the position.

    Any advice?

  • guys if i update my watch like this, will i still have guarantee on my watch ??
