Problems with Caches Displaying on Oregon 600 in GPS technology and devices Posted July 28, 2016 As mentioned, I was using GSAK to upload the GGZ file to the 600. I have tried uploading the file as a GPX file through GSAK, which works normally on the 400, but not on the 600. Something has become corrupt somewhere... I'm looking for someone who can help identify how the caches are read by the unit, and if something can be done to get it to index those files properly. I can't even send an individual cache to the unit through the GC web site... the attributes of the cache will appear (parking, etc.,) but the cache itself will not show up. Weird things just seem to happen once in a while with Garmins. I had a Colorado once that stopped writing to the "geocaches.txt" file. Garmin eventually swapped out units for me when they weren't able to solve it that time. Hi folks... any Garmin geniuses out there? I headed out on a big trip a few weeks ago, and loaded a few thousand caches into my Oregon 600. I immediately checked to be sure that they were appearing properly after I had loaded them, and they were working fine. Then I started my trip... and the cache icons failed to appear from that point forward (nor would they show up in the caching profile). Along my trip, I would see child waypoints pop up (trail heads, parking areas, etc.), but no other evidence of the caches themselves. I can assure you that I have already ruled out any of the semi-obvious problems... I was near the caches when trying to find them on the unit (not 100 miles away, where they wouldn't show up on the filter), for example. I have tried doing a hard reset, and I later updated to the newest firmware as well, both with no luck. I have tried loading some caches as GPX files, both individually, and as a batch, with no luck. My normal routine of using GSAK to load them as a GGZ file is not working. Everything does work properly on my old Oregon 400 using the same techniques. So it would appear that my unit is just not recognizing the caches for whatever reason. I did call Garmin, and they shrugged their shoulders because I had already done the things they would have suggested (factory reset, etc.). I just wanted to see if there's anyone here who is smarter than Garmin at their own products Garmin can take my unit for $99 and either fix it or send me a refurbished unit, but if there is something I can restore on my own, that's obviously my preference. Many thanks in advance for any help that you folks might have. I have read a little bit about Garmins having a problem indexing GPX files, etc., but I'm not sure if that plays into this or not.
