Nuvi Pre-boot Mode

**catymag** · 29th December 2011, 03:26 PM

Is your Nuvi set as Storage mode as said in post n3 ?

Steps used to access pre-boot
3. turn off the gps by press power button ~7 sec
4. turn back on, while the garmin logo is showing, put your finger on top of "RM" area, when you should see the word "system" flashing, plug in your USB cable right away, now the updater should recognize the device. But make sure you click OK fast enough, before the "system" went away. I've been trying this whole day, finally figure out.

and lastly:
Garmin Cure 3 used to do the flash... Tool was very easy and worked flawlessly!!

OK, so I couldn't get any of the fixes to work, couldn't even get my unit to be recognized by my PC. But I left it plugged in to a charger for a couple of weeks - AND IT CAME BACK TO ITS FULLY NORMAL & OPERATIONS STATE. There is no rational explanation for this I can imagine - other that just dumb luck.

@Fabio Miguel
try this:
turn nüvi on, enter diagnostic mode by pressing battery icon for 5 seconds and then connect USB cable to computer.
Hold the power button, immediately as Garmin logo appears, press upper left corner
