Forerunner 965 location suddenly very off

Hi all,

I've had my Forerunner 965 for about a year, and very happy with it up untill a few weeks ago. I noticed the location suddenly was off by a substantional margin, which makes pace based training quite annoying as you can imagine.

Below are two screenshots from Garmin connect of a similar training of two loops. It is clear that one of the two is off by a big margin. The wrong location training was this week, I grabbed a similar training from a few months ago to compare and was quite shocked:

Location wrong Location right

Apart from normal software updates, nothing was changes in the watch. When I noticed the discrapency, I changes the running satellite settings to 'All + Multi-Band' as it says this should have the best accuracy, but this changed nothing. The screenshot of the wrong location is with this setting.

Anyone has experienced anything similar and has found a solution? Or anyone has tips on settings to look at to improve this?

Hopefully I can do without a factory reset, as it will take time to regain HRV info etcetera.

Thanks in advance!

sync with garmin connect, a do a reset to defaults in the watch, it would help. HRV data and more its only deleted when is selected factory settings default and erase all data, just do a normal reset to default

Thanks for your reply! I didn't know about this reset, I just did it and will go for a run tomorrow. I'll post an update if this helped or not.

Ran the same loop a few times today after a reset to default settings. Unfortunately the reset did nothing, and it is still off by the same margin.

After reset

Guess I'll contact support, this is unacceptable for a watch with this price and I cannot understand why it would work perfectly for a few months and suddenly became this wrong. Very frustrating...
