Trick that you describe is useful to download upgrade using WebUpdater. I think you should copy GarminDevice.xml to \Garmin directory on SD

Yes., you are right. But you can try to place GarminDevice.xml in root directory of SD Card and Webupdater can also detect the SD Card as Nuvi. This method is the better way for updating firmware. The .gcd file will come to SD Card instead the Nuvi. Just copy .gcd file place in Nuvi later., Nuvi will update the firmware automatically when you disconnect Nuvi from USB. It's work fine and you don't worry about the internet disconnect during your updating firmware.
