Geocash.com ?

Do you mean Geocaching.com?

Does seem to be a problem with any of the add-ons for sending gpx files to GPS units.
Most browsers are not allowing the add-ons... Windows 10 seems to be one of the bigger offenders.


Seems Pocket Queries or third party software is the way to go.


From one of the many threads on the groundspeak forums:

Unfortunately all browsers are withdrawing support for NPAPI plug ins, it's not Garmin doing it. At the moment you can see what bowsers still support GCP here http://www8.garmin.c...s/communicator/ by selecting the View downloads and compatibility link.
