We have an eTrex 20, and missing downloads have been a recurring problem with our receiver. We think the caches are in there, the screen says “download successful”, and so on, but when we go to look for them, they are nowhere to be found on the receiver. This is really bad when we are traveling… like when we “lost” everything we had loaded for a trip to Alaska. 😕 Not too long ago we had to turn around to reload some caches when we found they weren’t on the the receiver anywhere. Lost a whole hour on that effort.
I don’t know how many caches the eTrex 20 holds, but it’s a lot. Your problem has nothing to do with memory. Contacting Garmin about this issue was useless. We have learned to check each time after loading caches to make sure that they are in the receiver… and then we double-check later… and triple-check before we head out.
