Hello. I also have a TomTom 7250 pro Telematics I unlocked it, but I still can't put the maps in his internal memory either. I was thinking of a variant. If I managed to unmount the backup image I made to the gps and put the maps and then upload the backup back to the gps and follow the unlock process again with the truck maps already put in it could work.
Does anyone know a program that unmount the image created from the backup?
