Thanks for the reply.

Sorry since I am not familiar about the process but when I connect the nuvi to the computer it doesn't recognize anymore as mass storage.

As for "Have you tried to simply re-load the firmware by flashing the RGN file in preboot using Updater.exe?" How do I do this? Is the Updater.exe the same with the GarminCure 3? If its not do you know where I can download it?

Thank you.
