But make sure you click OK fast enough, before the "system" went away. I've been trying this whole day, finally figure out.

firmware used:
nuvi37xx_GCDFile__430.cgd

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

Where did you find the firmware file?
I accidentally formated nuvi 1350 and now its not detected by PC. I have back up of the files in the gps.
I want to try GarminCure 3 but i need the firmware file. HELP!!!
