Hi,
My forerunner 405CX started experiencing issues where it says it is 100% charged and keeps saying it is 100% charged until is suddenly drops down to 0%. Same issue occurs when charging the device as well. It will say it is at 0% and then jump right to 100%. This is a known issue apparently with the watch as seen here in the software notes: https://www8.garmin.com/support/down...ls.jsp?id=4462.
So now I am trying to update my Forerunner 405CX from version 2.3 to version 2.4. Garmin express is fully updated (Version 6.4.0.0) and it says my 405CX is at version 2.3 and "up to date" when that is clearly not the case. Has anyone found any way to perform the update from version 2.3 to version 2.4.
Thanks for the help!
