Forerunner 945 LTE dies during activities and resets after latest update

I bought a Forerunner 945 LTE from garmin.com and received it on Jan 11. I took it out for a walk that day and it worked seamlessly.

At some point between Jan 11 evening and Jan 12 mid day, the watch installed at least one software update. I had seen the message like “sending update to watch” in the app, but I did not start the update, so I can only assume it started by itself.

Since then, my activities crash, often at the 1:04-1:05 mark, with the watch restarting.

See this series of activities. I was swimming in open water between two poles roughly 100m apart.

I read somewhere that it might be a wiring issue, so I started a walk session on the couch. Same result. In particular, same 1:04 duration before the crash.

Between the timeline of the update and the fact that the crash happens at the same duration, I’d say this is a software, not hardware issue. Fingers crossed, I guess. Otherwise, the watch is unusable as a training device, and I'd have to send it back.

I’m based in Australia and experienced the issue on LTE. I saw another post of someone saying they were in Australia when the watch started playing up.

For what is worth, I hereby give Garmin support staff approval to access my data in order to diagnose this issue.

    I’m skeptical that this will fix it, since gps is off during pool swims and I couldn’t get it to run for more than a minute at a time at the pool yesterday.

    What I have found so far after talking to Garmin is that after a full reset of the watch and deleting the app and Bluetooth  the watch in activities etc functions fine. But as soon as you connect thdd ex phobe , Bluetooth , and lte the phone crashes, on an activity it only gets to about 1.04 - 1.18 and then drops out and restarts, and then after this and deleting the phone app and Bluetooth again the watch continues to restart  until you go and do a full hard reboot delete of the watch setup again

    So you reset the watch and then delete Garmin Connect from your phone and turn off Bluetooth? Yikes. 

    I can’t tell if Garmin Support is taking this seriously or not. I’ve been sending them files and videos all day, but this seems like a show stopper bug to me.

    Yeah, I can’t believe how much of a pain this has been , brand new watch with lte for a reason, and it has done nothing but disappoint me from first use.

    After talking to Garmin today, it turns out ( apparently ) that the watch has a fault and I can either send it back to Garmin so the engineers can find the problem and fix it,. I still cant see how with numerous guys having this same sort of problem though that it’s not a software thing from the update

    Hello, just curious if this fixed it for you? I ended up getting a replacement as well and just successfully did a 5 mile run

    Thank you for sharing . Glad it worked out for you!

    Just to confirm, did you have LTE on for your run? I found that turning off LTE is the safest way for me to not get the crash.

    I’m hesitant to send back my watch because I love using it, but I guess if it really works out in the end, it’s better to bite the bullet.

    Thanks!

    Hi Gio, sorry to get everyone’s hopes up, I talked to soon, just did a map update on Garmin express and now the watch is doing exactly what my original one did , just spoke to Garmin, and now have to do the full master reset thing, see what it does , and then get info to engineers. I can’t believe one minute it was fine, it does a map update and then continually crashes the watch a minute or so in on run activity when started

    And sorry Gio, yes I did have lte turned on during run activity

    Oh man, I'm sorry this happened to you. 

    Thank you for keeping the thread up to date.

    At this point, this can only be a software issue. Fingers crossed they'll ship a fix soon.
