    Default Kenwood DNX4150BT fw downgrade

    Good day!
    Is it possible to downgrade the firmware in Kenwood dnx4150bt?
    Some maps are no longer visible after updating the firmware to the latest firmware 1.7.0. Apparently added additional protection against "unlocked" maps.
    The device does not see the old firmware 1.6.0 on the flash drive.

    Please try to rename your maps on your memory card, like gmapsupp.img, gmapsup1.img, gmapsup2.img and so on. You can still use unlocked image maps.

    Thanks! Now my dnx4150bt with firmware 1.7.0 sees maps from the external sd-card from the Garmin folder with the names gmapsupp, gmapsup1 and gmap3d only.
