    Default garmin nuvi 3790T problem

    Hi I have a Nuvi 3790 t, which when turned on will not let me continue, stays in Select a Locale and does not give me options.
    The PC did not recognize the device and I can not use WepUpdater.
    Only detects it if I hold down the screen in the top left for a few seconds, by displaying the text "system" and then "loading ..", then switches off and returns again to the screen "Select a locale "
    Anyone know what I can do??
    thanks in advance

    Your Nuvi is stuck like that because internal hard drive was formatted or the partition was deleted.
    You're nuvi is entering pre-boot mode because it says system and loading.

    You're best bet is to follow this thread.

    I found a way to recover deleted partition. After flashed my GPS original firmware, I got back the GPS drive and after formatting and copied the backup files, guess what - my Nuvi3790T fully resurrected and works like new. I am very pleased.

    Check to see if you can see the Nuvi in Disk Management (Computer Management Storage Disk Management)
    If you can see it then create partition Fat32
    SD Card must be formatted Fat32 not NTFS

    Did something change after you flashed the Nuvi.

    If the cure Firmware flashed properly the device should go into Mass Storage Mode (Kunix is a Genius). Been There Done This Many Times.
    It should not boot completely.
    Maybe Region 41 is corrupt (But that's another Story Altogether)
    Did you use the correct Firmware for 37xx. Try again with another older version of 37xx Firmware.
    Did you buy it from e-bay or similar ?
    Maybe this device is not Fixable.
