I have been using my etrex 20 for a month and everything has been fine. I downloaded about 100 new caches last night the way I normally do. It said I had successfully saved the file etc. Turned the GPS on today and none of the caches are showing in the GPS. Looking at the file on the computer, it shows that I did download the files. Help, I've missed out an a whole day of caching because of this....
