If the gadget is a GT-11, then the rightful owner should be able to tell you the name put in the unit under the settings menu. If you have not set this on your Navi GT, then do it now!
Well, I have tried to refrain from saying too much about it so I have a way for the owner to show me it is definitely his. Caller just now was a great help! He established it isn't his and helped me check it out, as I didn't know how to open it or access the settings or SD card. Charge was about 25% and I am now charging it.
User name is default so no help there.
And it was on the grass about 5m NE of the washdown point. I asked everyone nearby but no takers.
