    You made something wrong and probably you lost model number, I hope you havent lost ID too. What do you have in Info/About? Have you done NV backup as written in post n1 ?

    The most important is NV backup (region 41). If you have a backup just flash it back.

    dear all,
    this is my first post.
    great jobs, not only this thread.

    I followed all the steps, new method, and i was able to convert a 3760t into 3490. It worked fine for a week, and after that started a strange behavior: it starts up and instead of showing the map show only a gray screen. just instead of maps. I see all the other icons etc. It even works correctly, telling me where to go (upper of the screen and voice navigation).

    my current setup is: all the EU 2013.30 maps on a 8gb microsd, as well as 3d trafic and buildings and all the other big files.

    sometimes, removing and re-inserting the sd card it start working, other no.

    can anyone help me? is this a matter of the sd itself? but why the navigation works fine, even if not showing it on the screen? is there any logfile i can look at to see for the problem?
    thank you

    If you have any other Mapsets in Your Nuvi Delete them. (Don't just deselect them, Delete them)
    I've had the same problem when I have a lot of Mapsets in the Nuvi. (Real 3490LMT)
    Perform Hard Reset
    From Master Volume Screen in Landscape Mode
    Press Right Top Corner for 10 Seconds
    Then Clear all user Data.

    You can also try holding the power switch down for more than 10 seconds for quick fix.
    It will reboot the nuvi to reload map data from SD Card.

    @dasilvarsa
    thank you for your prompt response. I will try both (first the quick fix) this evening while going back home. I found also that if you remove and or insert the sd while navigating, the unit show a popup saying it will reboot in 5 second to reload all the maps. Is it the same thing?

    Yes Similar,
    I don't yet feel comfortable in "hot docking" SD in a Nuvi.
    10 second reboot is called by Garmin a "Reset" Fix for any problem Ha Ha.
    I still find that a "Hard Reset" is the best for fixing Strange Problems in Nuvi as it clears NVRAM.
    If you have "TRIPS" in your Nuvi copy /.System/Trips folder to Computer before Hard Reset and restore after Hard Reset and your Trips will be back.
    Use Basecamp to Back up your Favourites before Hard Reset.

    When you insert SD Nuvi reboots to verify if there are unlock codes available for maps on SD card.

    i tried reset (10 sec power button), hard reset, created a small map for italy, put it on the navigator internale memory, deleted the old big eu map (3gb), rebuilt it via mapsource, and this morning it did it again.

    fortunately, having the small map of italy, I disabled the full eu map, one reboot, and it worked. It also works 3d buildings, and the file is on the SD ...

    sorry for spamming this thread, I guess now my problem is more related to the SD card / garbage on the navigator / wrong procedure in building the eu map from mapsource/ whatever else. which is the correct thread for this?

    i will try it again in 10 minutes, while going back home.
