  • For any issues that you encounter please fill out the form included in the download and attach it to an email to [email protected]. Please note that you may not get a response to the email unless we need more information on the issue you report.
  • Although this software is believed to be reliable, it has not yet been released for production and should be used at your own risk.

Changes made from version 3.46 to 3.52:

  • Fix for Wi-Fi 0200 error when syncing Spotify (245M only) 
  • Improvements to sensor connection
  • Improvements to phone connectivity
  • Fix backlight gesture bug introduced in 3.46 beta
  • Various other bug fixes and improvements

Installation Instructions

  1. Connect your Forerunner 245 Music to your computer using the USB cable.
  2. Download and unzip Forerunner245M_352Beta.zip. Place the GUPDATE.GCD file in the \GARMIN folder of your device's internal storage drive.
  3. In Forerunner245M_352Beta, go to the RemoteSW folder. Place the GUP3205.GCD and GUP3079.GCD file in the \GARMIN\REMOTESW folder of your device's internal storage drive.
  4. Disconnect your device from the computer, approve the update on the watch, and wait for the update to finish.
  5. If you would like to revert to the last public release software, place the GUPDATE-310.GCD file in the \GARMIN folder. Rename GUPDATE-310.GCD to GUPDATE.GCD before disconnecting your device. To revert the RemoteSW, place the GUP3205-360.GCD and GUP3079-250.GCD files from RemoteSW\Downgrades in the \GARMIN\REMOTESW folder. NOTE: If you revert to an older version of software, all of your settings will be reset to defaults.

    No difference for me, it still locks on to my cadence for most of my run. I don't trust it at all now and have bought a Wahoo arm band which works perfectly. Not particularly happy with the Garmin quality, especially in relation to price. I've had to spend an extra $80 to provide the main functionality that this watch was purchased for.

    how to do this : Place the GUPDATE.GCD file in the \GARMIN folder of your device's internal storage drive.

    Then you have probably used the wrong firmware update. If you use 245 beta files on 245 Music, the watch will not go into update mode. Vice versa.

    I'm not sure but i feel like wrist HR accuracy has improved. As i've been doing workouts for years, i know what my heart rate is roughly. Before 3.52 update, my watch seldomly shows +100 bpm while walking in fast pace. But after update, HR performance has been more accurate, i see +100 heart rates.

    Might be a stupid question, but where do I find the \GARMIN and \GARMIN\REMOTESW folders? Would love to try the update to see if it solves my HR issues as I really dont want the send it for service and wait for a few weeks / months. I´ve only had the watch for under two months.

    Do you run with music on?

    I run with GPS and music on( spotify offline, no phone).

    My battery drains approx 20-22% in one hour run in above settings.

    Is it normal?

    Currently v 3.7.
