I have a full memory need to delete files and forgot how

Perhaps removing the batteryz and replacing it will reset it..

Just press the video for a moment then there should be options to select then select delete or go into files and select from the drop down menu delete files and select the two that are unwanted!

Once you reset the watch then connect to PC and on Garmin connect you should see the memory then clear back down. Make sure all files when plugged in are either backed up or cleared.

I got last year same problem, easy to resolve :) I was doigng GC and i got my watch in failur exactly like yours. Solution? Buy 4 fresh, alkaline, good brand batteries. Put it in charger unit. Let the watch to charge for 12hours. After do garbage collection again or formatting if you cant do GC. If you got again fail, charge again it for 12 hours. I did it for 3 times and...the third days, I got "Done!" and solved :) It happens when battery is not full charged, so do GC just when is very charged. I love my Cyber, but sicne seems that GC collecting drink a lot of energy seems that low level battery doesnt let the inside flash memory to work well when try to format/GC datas.
