It is always a good idea to back up the unit before upgrading anything. If using windows make sure 'system and hidden' files are showing in 'Explorer', then copy the Garmin unit folder onto HDD somewhere. It will have all the files. Check and make sure there is also a .system folder as that is normally a 'system/hidden' and wont copy unless Explorers properties are set correctly.
Glad you got it working again.
