Does not work on my 760. This is what I do, please advise if I'm doing something wrong:
- copied the package onto a SanDisk SD 2 GB card (with a 10 digit serial no. :-)
- at that point, the SD card contains: a main directory called Garmin - which contains a subdirectory called LEX_PKG and a gmapsupp.unl.
- ran keygen 1.5 with “Garmin Language Guide” in the “Select Map Product” field and added the key to the .unl file.
- turned on the 760 without the SD card. Inserted the SD card.
- at this point, I expected to get an installation request. However the SD card is just ignored.
