My settings are for Basecamp map data in UTM and US units but exporting the waypoints to a csv file results in Lat Long and meters. I see no settings to correct this. Help appreciated
You can do this using other software, eg Garmin MapSource. You can copy waypoints/routes/tracks from BaseCamp, then paste into MapSource. Then export as a text file (tab delimited), it will be in whatever position format and units that MapSource is set to use.
Or export from BaseCamp as a GPX, then use GPSBabel to convert to what format of CSV you want.
