Bluetooth Frustrations

When I had my FR235, if I got too far from my iphone I would lose bluetooth signal as expected, but once I came within range of my iphone again, the FR235 reconnected instantly.... With the Garmin FR645 Music, once I leave that bluetooth range, it NEVER reconnects to my iphone. I have to restart, or turn off and back on bluetooth, or close down and re open up the garmin app.. it is so annoying. Why isn't this as good or better than the FR235 which is like 3 years old???? Am I the only one having this issue. I was hopeful with each update it would be addressed, but still an issue. If I stay in range, it is good to go, but the second you are too far from your phone and then come back into range, it doesn't auto connect bluetooth. All manual process to reconnect and utterly frustrating!! This is easy to test out.. walk away from your Iphone for a couple minutes more than 35 feet away... when you come back it never reconnects without manually resetting the app, the watch and/or the iphone...... PLEASE FIX Garmin!


I am on an Iphone 8 with always the latest IOS version. This has been an issue since Day 1 of owning the FR645 Music.

    My "fix" of disconnecting FB messenger has failed...I am back to the same as everyone else on this topic. FR645M disconnects and never re-connects unless I do one of 2 or 3 functions that will get it to reconnect. I wanted to test to see how long it would take to reconnect and I am at 24 hrs, not connecting with phone 5" away. Very annoying and should not be happening, obviously a serious issue. I raised a support ticket and nothing came of it. I am done with this watch, returning it to REI for full refund and switching to something that will work, like Apple watch, it is even cheaper than this watch. And, Garmin Pay never worked nor could I load music. I am a long time user of Garmin; this is a huge disappointment that Garmin hasn't figured out a fix for this.
  • Garmin Joey --- Any word on the next firmware release date and if this is finally going to address the inability for the 645 music to reconnect to bluetooth on phones???
  • Anyone notice any improvement in the Bluetooth area in FW 4.00 with this noted issue in this thread? Downloading FW 4.00 now, I pray this is fixed.
  • Still no update and still constant daily disconnects to iphone from Music Garmin 645. I am beyond frustrated that I have to turn off and on my bluetooth multiple times a day for my $450 dollar watch to be "smart". 8 months this phone has been mainstream and NO FIX!
  • Same problem with my brand new 645 non music.
    Hope they will fix asap.

    I have the same problem.  iPhone XS. Have to repair my watch more than once every day. Started about a month ago. Watch was great for a year and a half!!!! Have you fixed the problem?

  • The same problem here, iPhone 12 mini + Forerunner 645 music, is somebody aware of perm. fix?

  • It only tries so many times to reconnect after it sort of gives up.

    Switch off Bluetooth on the Phone and Switch on again after a few seconds.

    Keep the phone close to the Watch. Same Side of Body.

    Limit the number of paired devices on the phone. Bluetooth is Weak....................
