Garmin 645 Music firmware Version 5.7

8356359 over 4 years ago

Since, the latest version 5.7 of firmware update; the SW is not more stable.

Today during running, 1h 20 min ( Watch connected to headphones),

the watch loses the connection with heaphones at least 10 times, and the headphnes watch restarts 3 times!

This was not happening with the previous versions.

Same issue with my 645. Since 5.7 bluetooth connection (with headphones connected) is always crashing during a run. The only solution is to restart the complete watch (which is very annoying during a run).

Same, I reverted back to 4.2 (Installed Beta 5.73 then took the 4.2 firmware that is in the 5.17 beta (yes, older beta) and installed it and disabled auto firmware upgrade). Watch is working perfectly again and GPS is much better.

Successfully reverted to FW 4.20 using your link. Now the treadmill distance estimate is back on track. 1000 thanks for your help!

How is the barometer with 4.2 firmware? My watch works correctly, but altitude is all over the place: today on a flat run I climbed 14 floors, apparently.
