Software missing where can I recover system Software for my dezl 760LM?

SOURCE: Nuvi 350 System Software Missing

Try this: Hold the power buuton down, you will see on the lower screen the word "Pre Booting - ". Keep holding the power button for about 60 second, then you will see on the lower screen "Booting".
This time, release power button; system will reboot and loading map... again.
I got the same problem, after research on the web. Nick 99990_0 had post this solution on (his Nuvi 660) but it work for my Nuvi 350 too. Good luck.

I did exactly the same thing!. This is how I fixed it.
Use Updater.exe NOT WebUpdate. Download the latest firmware for your unit (the rgn file), then connect your nuvi via usb. Turn it on and hold the power button left, at the same time drag and drop the rgn file onto the Updater,exe. It will start automatically and reload the firmware over the corrupt one.

Here are the files:-

You can go to this site and get the update that should put them on there: http://www8.garmin.com/support/collection.jsp?product=010-00656-00

If you have a nuvi 350 download the software to your computer and then load the software onto a formatted sd card. Insert the sd card and bootup the Nuvi 350. The sofware will then load onto the Nuvi 350. If you have a Nuvi 200 I would think it works the same but I have not tried it.
Hope this helps

If the unit indicates "software/firmware missing", then you can only try to re-install firmware by running WebUpdater again. If it doesn't work, then the unit has to be sent to service to have it re-flashed.
