OK, I discovered your tutorial while doing some hopeful googling, and boy was I happily suprised! The steps are complicated, but your tutorial really makes it easy (yes, I struggle with computers). This finally convinced me to get a premium membership. I am in awe of the entire process.
We have a 350 but haven't used it for caching before. We have an old yellow etrex that we use I need to get the connector cord for, and then caching will be complete heaven. I can't tell you how many times I've dreaded the printing, organzing, and putting coords into the GPS routine.
THANK YOU!
