    Default nuvi 3790t stuck

    After (apparently) botched map update it hangs at "loading maps".

    I used garmin cure3 to generate emergency firmware but I can't flash it - my computer won't recognize the device so updater.exe does nothing.

    Tried this: connected the unit via its usb cable, held my finger at upper left corner so it enters pre-boot mode (showing "system" message) and waited for the computer to recognize it as usb device - but that doesn't happen; after a very brief period during which it appears on devices list and drivers start being searched for, the computer rejects it.

    Any ideas?

    You must add finger above letter G of name Garmin and you must have installed garmin drivers from garmin page.

    Go to Tutorial index and you will find what you mus do: [Only registered and activated users can see links. ]
