Have you try contacting Garmin? Garmin Support

"Try this:

Plug your unit into the USB port on your computer. A file will pop up that says “Garmin”. Click on that.On the next list of files that come up, click on “Garmin”.In the next list of files that come3 up, click on “Garmin Device”. It is a small text file.About 12 lines down in the text file will be a line that says, “<UNLOCK><CODE>.I can’t promise that is THE code you need, but it is worth a try."
