this is the procedure to install it in nuvi, I dont know if it works in phones, I havent tested
Steps:
1) Get the ID of your SD card. If the SD card is inserted on the Nuvi from the main screen of the nuvi, hold the top right part of the screen for 10 seconds until you see the debug menu. Page through 3 pages and you will see the SD card test menu and that page gives you the SD Card ID. Note down this ID
2) Use JetMouse Keygen to generate the unlock code for the Language card using the Card ID obtained in step 1. Cut & paste this code to a file called GMAPSUPP.UNL
3) Create a folder called Garmin on the SD card
4) Create another folder called LEX_PKG under the Garmin folder (Garmin/LEX_PKG)
5) Copy the Language Guide files & folders to Garmin/LEX_PKG
6) Copy GMAPSUPP.UNL to Garmin folder
7) Insert SD card into Nuvi
8) Start your Nuvi. If the code is correct, the nuvi will recognize it and ask you permission to copy the files to its internal disk. If code is wrong, then nothing will happen.
good luck and give us feedback please
