It worked to unlock the "Routes" utility and my Garmin Language Guide (with a .unl code also generated) on my nüvi 1300 (that is the only way that i found for unlocking the Language Guide on a nüvi 1300, because includes the GMA lock )

I did this with the GPS fully actualized and finally i can use BaseCamp and my 1300 for other functions that are not only Car, car or car XD
