Thread: Nuvi 3790. Disappeared features? Model# loss problems ?

Well, I restaured the backup and the unit still with the same problems:

- pop-up message stating "maps cannot be unlocked"
- the CN North America map disaperared; the only thing left is the DEM map, which is not enough for routing

Does anyone care to coment ?

Thanks
