yes i did, to be more detail, i did in the way below: but still can not see in the installed map list.
Find out your 10 digit gps unit id number before running Jetmouse! It has nothing to do with the serial number printed on the unit. Plug your GPS into a USB port on your computer. Once the green line finishes and the computer symbol is on the GPS screen, run the Garmin WebUpdater program. The UNIT ID will show up. Store this number into a text file so you don't have to look it up every time you want to unlock something. Call in 1390 Unit ID.txt or whatever.
Run Garmin Keygen (aka Jetmouse). Put in your 10 number Unit Id number. Select custommapset from the BOTTOM Map Product and not the top software Product. Put in 800 into the FID box and leave the rest alone. Click OK then on the Generate button on the BOTTOM. Copy the generated code and store it into a txt file named Full CXNA 2012.30.txt . Change the extension from .txt to .unl
On a SD card, create a FOLDER called Map . In that folder put
Full CXNA 2014.10.img
Full CXNA 2014.10.unl
