Dear catymag,

Thanks a lot for your concern.

Unfortunately, my laptop couldn't connect with my Garmin etrex20 using the USB cable. So, I cannot copy any file to my etrex20. I tried to preboot it by holding the stick in the up position (and down position on the second time) during the entire load process, but all those attempts were failed to load the system.

Also, I have downloaded the Garmin Updater and GarminCure3.exe, so, please what I have to do?
