Shouldn't there be an EPO.BIN file under Garmin/RemoteSW on the device, providing satellite location data? I thought there would be and that Garmin Express would update it necessary - but the folder is empty after synching with Express or Connect.
EDIT: Answered my own question. EPO.BIN is in the folder Garmin/GPS (an old post had pointed me to Garmin/RemoteSW).
