Hi, a have several gps units, some old NUVI's, an Oregon 450 and a few days I bought also a 62 SC unit for my son. The problem is that I always update all the other Garmin units but can't update this new one, that came without map.
I tried to load it with the CNEurope 2015.20, that I have installed in my Mapsource and also in my Basecamp, also tried wit Mapinstall and always received the gps message "CAN'T AUTHENTICATE MAPS".
I have that map unlocked and it work well on the other units, so it must be a new security issue of the new units... is there anythnig that I can do?
Thanks
