Thanks guys, you also save a Nuvi 1490.
What i do:
First i use GarminCure with Cure option... device booted then i copy all data from Nuvi
Then i format the navi with RMPRepUSB like [Only registered and activated users can see links. ]
After the format i use again GarminCure with Original option
All was ok the device booted and now is ok.
Again thanks for all!!!!!
