    I only need to flash slightly patched fw_all.bin (infinite loops and forced reboots to bootloader will be inserted), nothing else. It's not dangerous.

    Hmm.. interesting. Can the garmin or distributors are doing the same, ie, reprogramming of stranded stocks of 37xx to 3490? Find really very likely. I have in hand a 3490, new, newly-acquired in a forgotten country in South America, which has a peculiarity: it only has 2 GB of internal memory (V7 2 GB TC DS 036 GTL), being new and not refurbished (ID 385...). Another curiosity that makes me think being a 37xx reprogrammed is being able to get in 3 different ways of pre-boot: pressing the top left corner of the screen, when it appears the Garmin logo, exactly as in the 37xx, or pressed ON or ABOVE the Garmin logo G (can someone confirm if the 3 method also occurs in the 3490 previous?). In the 3790 are 2 methods: pressing the top left corner of the screen or above of the G of the Garmin logo. From what I remember, in 3490 firmware only if enters in pre-boot by pressing up ON the letter G when appears the logo on the screen. A nothing sophisticated method to be more certain would be to open the unit and check which processor is used. Finally, at least the accuracy is impeccable, really great, similar to 3790 with original fw...

    Dunno if the 2GB is any indication, all 34's sold here have only 2GB and my 4 months old 3590 also has only 2GB. I haven't got an original 34x0 to try, but my 3590 goes into preboot only by pressing 'G'.

    It depends on country which memory size you get. (Depending on the size of preloaded Maps)
    South Africa and Australia only gets 2GB units as well. (Small Maps)
    Europe gets =>4 GB because of Large Map.
    3490's are not Refurbished 3790's
    If you open both you will see differences.
    Different GPS/Bluetooth Chipsets.
