Garmin forerunner 405 firmware upgrade

Former Member

Apologies if this has been asked before.

I discovered today that I am using an old version of the firmware.

Are any of you aware of any way to upgrade with 405 firmware for 2.50 to 2.80?

The communicator plugin states it is up to date but Garmin connect claims it is old.




Garmin Express will not update the firmware, claiming it is up to date.

To get Garmin communicator working I am using the https://connect.garmin.com/api/device/widget/firmwareUpdate.faces URL.

Perhaps it is no longer supported?
