I had to replace my 450 on a recent trip because of a defect and I now have waypoints and routes from that trip on my new unit that I want to sync with the old files I have on Basecamp. Is there a way to sync the files without the new files over writing the old files when I plug the unit into my mac?
Your new files won't overwrite the old ones as there is no automatic 'sync'. If you try to copy files with the same name from your GPS into BC then BC will rename them.
