BaseCamp may display the error "There was a problem communicating with the Garmin device" if corrupt data is encountered on a connected device.
Corrupted files that may cause this issue include the following file types:
GPX (Waypoints, Tracks and/or Geocaches)
JNX (Birdseye files)
JPG (Pictures)
You need to delete the corrupted file from the GPS internal storage using the Windows or Mac File Explorer. You cannot delete them through Basecamp.
Once you have located the Garmin Internal Storage in the relevant File Explorer (denoted by a blue triangle), Double click on the word 'Garmin' and find the 'GPX folder'
Having opened up the GPX folder, find the relevant corrupt gpx file/s and delete them. There is no 'repair facility'.
WE URGE GREAT CARE IN DOING THIS AND THIS IS DONE AT YOUR OWN RISK. WE DO NOT ACCEPT LIABILITY SHOULD YOU DELETE THE WRONG FOLDER OR FILE (it is useful to have the corrupt message window open at the same time so that you can compare the files to identify the corrupt file/files).
Once you have deleted the corrupt file/s, disconnect the GPS and then reconnect the GPS and the GPS will be read by Basecamp in the normal way
