I have tried installing an updated driver from Garmin for my etrex 20x, I have installed Garmin Express and it recognises the device but when I go on to Geocaching.com to add a cache by finding it on the "Play" and "View Geocaching map" area as suggested on a You Tube tutorial, I get the message "Garmin Plugin NOT detected Download & install". When you try to install you are told the plugin is no longer supported and I have uninstalled Chrome which seemed to be the problem but this has made no difference. I am now running out of ideas and any help would be gratefully received
