Hi again
This method for unlock works perfect
[Please Register or Login to download file] Than I installed IGo 8.3.... To avoid the problem of low memory from other versions 9... It must contain two files one named with numbers and other file named Igo (in root of sdcard)
With the explorer of your enter Igo file and open Igo.exe .
Enjoy
NB: You can add you country map in /Igo/content/maps , and don't forget basemap....
