Cant seem to get it to work, on a Nuvi 775T(compatible according to the LOC8 website).
I made a notepad file with the jetmouse code for my unit ID pasted into it(using the FID 2124), then saved the notepad file as LOC8.UNL onto my desktop (saved as 'all files' rather than .txt, is this right?), then I put the notepad file into the Garmin folder in the Main unit memory. Tried to test it using my own generated postal code, but it could not detect it on the unit, and it asked me for my house number and address anyway. Did I do all the steps correctly?
