Hi. Since upgrading to the latest firmware, version 7 5, I can't upload my ride files, either automatically or via USB. The ride is in my history on the unit but will not upload. When I try to upload from the history either the upload button doesn't appear or if it does I get an Upload Failed message. When I plug the device into my PC the PC does not see it. I have tried restarting the unit and logging out of and back into Garmin Connect. Any suggestions? Thanks.
