I have downloaded the fullCXEU (289.1mb) file from this site and have tried to unlock it with Jetmouse. I used custom map and the FID 800,1,0,0 and generated a 25 digit number that i put into a .unl file. I then uploaded both the .img and the .unl file to my Nuvi 1340, but can not see it anywhere of the device. I have CNEu NT 2012.30 installed and working okay. Should the FID be just three figures? I would certainly apprciate any help and advic e.
