I’m sorry I’m not any help for finding your Garmin, but just wanted to offer a little advice for everyone else-
Load your personal info onto your Garmin, either at the startup screen:

Or if you have an older unit (like me)- load a text file into the memory! Last year, I found an older Edge on the side of the W&OD. It had been there for a WHILE!!! After taking it home, I remembered this tip and checked the files. Sure enough, the owner had loaded her info! She had lost it a couple months before!
