Installation Instructions

  1. Connect your Forerunner 935 to your computer using the USB cable.
  2. Download and unzip Forerunner935_1055Beta.zip. Place the GUPDATE.GCD file in the \GARMIN folder of your device's internal storage drive.
  3. Place the GUP2957.GCD file, found in the GPS_v224 folder, into the \GARMIN\REMOTESW folder of the device.
  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, follow the above steps, but place the GUPDATE-1010.GCD file in the \GARMIN folder. Rename GUPDATE-1010.GCD to GUPDATE.GCD before disconnecting your device. NOTE: If you revert to an older version of software, all of your settings will be reset to defaults.
