Unlike for some people, my watch worked very well with version 3.70 but subsequent versions have caused problems. I contacted Garmin support to ask how to rollback to 3.70 but they said that it is not possible. However I've been wondering, if I have a future version that works for me, how I can keep a copy of it to go back to. When I connect the watch to my PC there is a GARMIN folder. This contains several other folders. Perhaps keeping a copy of either the GARMIN folder or a relevant subfolder in it on my PC would help. Then if I had a future problem I could overwrite the new problem folder with my copy that worked OK. Using the whole GARMIN folder may lose data added since the original folder was copied but using a subfolder might just overwrite the software. Am I in the realms of fantasy?
