OK thanks , i have done it , but the trouble nowis when the device is on there is not any map recognized by it , i putted inside the garmin folder (in the root of the devide's memory) a basemap but the device doesn't see any map ;i downloaded from the map index the mapsource data 2015.20 locked ; intalled it + installed mapsource from garmin , then replaced the mapsource.exe by the patched one , after unlocked the map with JM-KG-v1.5+5Digit+ChecksumFix.exe ;

but iin mapsource impossible to select any map portion to send it to my devide ( in mapsource i choose the "select" tool to select map portions to send to the device , but when i clic on maps portion i whant to choose there is not any action....
bored with this device , since one week i am on it all the day time and no result ...
