I have been using Basecamp successfully to create and transfer sets of waypoints to the microsd card in my etrex 30. Garmin just put up a software update (Software version 4.20). The Waypoint Manager now reports 'No results found. Try adjusting search parameters' even though the file 'Waypoints' exists in the GPX folder in the Garmin folder on the card, exactly as it always did. I have tried sending another set of waypoints from Basecamp to the device, but these aren't shown either.
What has this software update done? Where are the waypoints? How can I use them on the etrex?
