I did the following:
1. Power OFF your Nuvi. / 2. Press and keep holding the most left upper corner of the LCD screen / 3. Power ON your Nuvi but DON NOT release your finger either from Power button nor from LCD screen (keep both pressed until the procedure ends) / 4. You will notice Nuvi boots in Pre-Boot mode. Now quickly connect your USB cable.

The PC recognizes the device for about 4 seconds and than not anymore.
The screen on the nuvi does not change at all, still the Garmin logo but nothing else.
Try little bit different way -
1. Power OFF your Nuvi and disconnect USB cable from PC.
2. Press and keep holding the most left upper corner of the LCD screen.
3. Power ON your Nuvi but DON NOT release your finger either from Power button nor from LCD screen (keep both pressed until the procedure ends)
4. Now quickly connect your USB cable
5. You will notice Nuvi boots in Pre-Boot mode.
