Hi all, very new to using GPS units, but I have a Garmin 62sc and would like to upload a set of cadastral boundaries (in shapefile format) from my PC to the device. I have converted the polygon file to polyline and successfully loaded them onto the Garmin, but they come out as a series of over 1,000 tracks. What I would like to achieve is having just the one layer. I've tried all sorts of options to no avail. Have also used a GPX to IMG converter and tried uploading as a map, but this produced an empty map. Can anyone advise what the best process would be to follow?
