Well, for an abandoned device (even the cheapo ones received more feature/updates than the 645) I don't much hope.

I'll keep posting all the crashes on [https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-645-645-m/230075/no-updates-for-7-months-and-my-645-keeps-crashing-while-hiking-running]. Maybe someday they'll have a look at my logs and commit a fix.

6.70 is working fine for me

0 Humschti over 4 years ago in reply to Winbatch

did you a "hard restart"? Long press the upper left button until the watch goes out?

0 Winbatch over 4 years ago in reply to Humschti

Yup. Note that the initial upgrade seemed to happen over WiFi. After it froze and I hard reset, I used Garmin Express on the computer then to sync as well to ensure everything was ok. It’s been ok after that (though it’s only been a day)

Fingers crossed, I haven't used it yet. 645/M firmware changed a year ago and wifi Spotify music sync became horrible. Sounds like Garmin is finally trying to address the issue. We'll see. Last weeks driver update to ANT/BT 5.04 seems to help me.

Had my first run with 6.70 this evening, all seemed as normal but going by the change log, very little has changed for the 645.

In Garmin Express it had a huge change log, but I can't seem to find it now that it's installed and can't seem to find it anywhere on garmin's website. Former Member - can you post the change log as shown by Garmin Express?

0 Attila_Molnar over 4 years ago in reply to Winbatch

I think, but maybe I am wrong, but there should be 2 changelogs. 645M received FW 6.60, so changlog is smaller than for 645 non-music, where the latest one was 6.40.

when can we expect support for wrist heart rate for swimming? Most other (even lower end) Forerunners have it...
