Hello friends, I've got a garmin nuvi 2659, it has the structure of the system hidden folder and the map folder.
Within the system folder it has a gmapprom and its corresponding unl (map of Europe) and within the map folder have a gmapsupp map (map of sudamerica).
I can not find the way to put new maps in it. It does not recognize the gmapsupp name within system folder , it's recognized gmapprom1 but appears the "you can not authenticate the maps" message and then "maps are damaged and can not be used". I am trying to install the map of USA but is impossible, I create an UNL file with the medicine placing the device ID, FID and PID map, but the same occurs.
Is there any solution to this?
I read somewhere that the new garmin of the "26x9" series have a new system of protection since 2014 to prevent the installation of unofficial maps. This is so?
Thank you very much!
