    Default Nuvi Pre-boot Mode

    Hi,

    I followed the following instructions posted on making a cure firmware but I was unable to get 2565 into pre-boot mode.
    Whenever windows 7 x64 detects the gps, it cannot install the device usb driver because the gps preboot mode only turns on for a few seconds.

    What steps have I missed?

    1. Power OFF your Nuvi.
    2. Press and keep holding the most left upper corner of the LCD screen
    3. Power ON your Nuvi but DON NOT release your finger either from Power button nor from LCD screen (keep both pressed until the procedure ends)
    4. You will notice Nuvi boots in Pre-Boot mode. Now quickly connect your USB cable.

    Regards

    Followed your instruction.
    Upon seeing the garmin power up, I released the power button while keep pressing the top-left corner of the LCD screen. This led the gps into screen calibration mode instead.

    This is normal, nuvi waits for about 30 seconds in pre-boot mode, if you don't start flashing in this time, it goes to calibration procedure.
    Thanks, Kanopus

    Don't you use updater.exe? This program should detect device in pre-boot mode.
    Thanks, Kanopus

    Thanks....The gps finally can be detected by updater.exe.

    Caty, I did set the gps in storage mode. Cannot find such setting in diagnostic page. But anyway, Kano's instructions helped. The gps is detected in the updater.exe for flashing.

    Thanks to both of you!

    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.

    firmware used:
    nuvi37xx_GCDFile__430.cgd

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