Forerunner 965 issues after update

Since the latest update my 965 has struggled to get a GPS lock. I've gone on my normal routes and during one 35 minute run it never got a signal. Then today, it was about 30 minutes into the run it for a signal. I've reset and reconnected and nothing. This only started after the update to 28.05.

The previous update had made my HR sensor unreliable. I start my run and it jumps to 150 then maybe 10-15 minutes later it's back down. On other activities it's reading maybe 60 BPM, but by other methods im easily double that.

With these two issues it's become nothing more than a stop watch ( an expensive one at that!)

Any thoughts on what to try before I do something drastic?

Menu - System - About - scroll down a few pages, and what is the firmware number of the GPS? 13.00 or 0.00?

13.00

By reset , do you mean you held the upper left button for 30seconds until it turns off ? If not, I would do that

Yes, that is what I did. I've powered off and on, and synched with my phone. The only thing I haven't done is delete the app, disconnect the Bluetooth and do a full reset

Pellettiere Although you've mentioned trying a few of these already, please be sure to review the suggestions outlined here: Garmin Device Takes a Long Time to Acquire GPS or Not Finding a Signal

I also suggest moving your watch to an open area away from tall buildings and trees, and remaining stationary for a few minutes. You could also try enabling secondary satellite constellations for a faster and more accurate GPS lock as explained here: Enabling Secondary Satellite Constellations on Your Garmin Watch or Edge Device

use always multiband-multignss "best" setting for every activity, and if you scroll down a lot in the watch on that mentioned "about" page, there is a "Ephemeris:" info , it should be Current , if it is Missing, that is a problem, you need to sync via BT/wifi/GE or after a sync it is still Missing, then you need to delete the files in RemoteSW folder and re-sync again. it should work

the optical HR sensor i think is not good for activity (for the majority of users), it is good only for restHR , when you are sitting or laying, but always use HR belt for running/cycling if you wanna ACCURATE HR measuring.

Yes I have done all of that. In addition I've been on the same route several times since the update. I've run the route many times before the update, 30 minutes to get a lock is a lot.

Note, I've tried all my satellite setting get from GPS only to find the best.

I have stood in open areas for several minutes and it will go into power save mode before it ever acquires a signal, and I have to keep telling it no. Or I just start an activity and hope it picks it up along the way.

This is only a 2 y/o watch and had been pretty good up to this point.

Thank you everyone for all the suggestions. I have done most of these already and keep trying.

I can not find the "ephemeris" on my watch or phone.

I agree with the assessment of the optical HR sensor, but it had been pretty good as long as it didn't track to cadence until the Jan updates. ITV tracked with my chest strap pretty well and even with what i could get from the gym.

Maybe there's more I can do, but it was working well before the update, so this seems like a lot and I've seen no improvements with will the time I've put in. If I get the time and energy, next step will be a full reset of the watch and wipe Garmin from my phone and start all over.

Ephemeris: System, About, keep scrolling, I think it's almost at the end. You can try syncing with Garmin Express via usb connected to a computer.

Pellettiere If you have access to a computer, then let's try plugging the watch in and syncing with Express. Doing so will push any missing or incomplete updates to the device, and will ensure that the GPS satellite data is up-to-date. If you don't have Garmin Express installed, you can find it here: Garmin.com/Express

If your watch is still unable to acquire satellites afterwards, please let us know and we'll take a closer look at what's going on. **
