How to Install Software Updates to My D2 Charlie Watch

D2™ Charlie watch software should be kept up-to-date in order to take advantage of improvements and bug fixes. Updates are free, and easy to install. Software updates can be installed through Garmin Connect™ app or Garmin Express™ program.

The Garmin Connect app will only download software updates automatically behind the scenes while your device is connected to your mobile phone. There are no steps required to obtain the latest software. Once an update has been sent to the watch, the watch will automatically install the update, or prompt the user for further action.
