    Idea How to Update Maps on your Device

    This is a simple guide for all people that never updated the Garmin device.

    Befor procced remember the FIRST RULE
    .: ALWAYS BACKUP YOUR DEVICE BEFORE UPDATING :.


    Garmin maps are .IMG files, so if you download some file named gmapprom.img or gmapsupp.img you don’t have to do something more, just use this file like they are (you don’t have to mount or burn this IMG files)
    In some threads you will find LOCKED and UNLOCKED IMG(map) files, you can use several TOOLS to unlock a locked map, is your choice, the unlocked maps are Copy&Go.

    There are different ways to update the map, it depends on your Garmin device.

    • The New Garmin Series (1xxx/2xxx/37xx)

    In this devices you will find built-in maps in .System folder, this is a hidden system folder and you have to enable the view of this folder in:
    Tools\Folder Options\View – Select Show hidden files, folders and drives
    Tools\Folder Options\View – Uncheck Hidde protected operating system file (Recommended)

    OR

    Control Panel\Folder Options\View – Select Show hidden files, folders and drives
    Control Panel\Folder Options\View – Uncheck Hidde protected operating system file (Recommended)



    To update this devices you can:
    1 - Replace the original map (gmapprom.img) with the one downloaded, you can rename the downloaded map in gmapprom.img if it is named gmapsupp.img
    2 – You can create a folder called Map in the root and put the map file inside. The files in Map folder can be renamed as you wish and you can put more than one map in this folder.
    Example: “X” is your Garmin driver
    X:\Map\gmapsupp.img
    X:\Map\Europe.img
    X:\Map\NorthAmerica.img
    X:\Map\XXXXX.img

    You can do the same in SD card
    SD:\Map\gmapsupp.img
    SD:\Map\Europe.img
    SD:\Map\NorthAmerica.img
    SD:\Map\XXXXX.img
    3 – You can use the Garmin folder in SD but you can use only one map, named gmapsupp.img

    • Other Garmin Devices

    In other garmin devices is not present the .System folder , all the maps will be inside Garmin folder, the same here gmapprom.img map is the original pre-installed map
    To update this devices you can:
    1 - Replace the original map (gmapprom.img) with the one downloaded, you can rename the downloaded map in gmapprom.img if it is named gmapsupp.img
    2 – You can use the downloaded map named gmapsupp.img just copy inside Garmin folder.
    3 – If you want to have more maps in your device you can rename maps file in:
    gmapprom.img (original map/ or renamed new map)
    gmapsupp.img (2° map)
    gmapprom1.img (3° map)
    gmapoem.img (4° map – can’t be unselected)
    devices with 3D buildings support, can rename in
    gmap3d1.img (5° map)

    4 – Using a SD card
    Format in Fat32 your SD card and create a Garmin folder. Copy the gmapsupp.img inside the Garmin folder. You can use only one map in SD card.
    You can have 2 maps named gmapsupp.img one in device and one in the SD card. It can help if you can’t put a full Europe map and you need a <2GB map. Copy the big one in SD and the rest usually a small file in Device, go in Setting\Map\Info and select both maps this way you will have a full coverage of Europe.

    • Garmin MobileXT

    In garmin MobileXT maps goes in Garmin folder in Device/SD. Remember that you can’t use maps bigger than 2GB.
    You can use maps named:
    gmapprom.img
    gmapsupp.img
    gmapsup2.img

    You will find the maps installed in your MobileXT in Tools\Manage My Data\Map Sets
    If you click MapSource you can Select/Unselect the maps you want to use.

    • Garmin MobilePC

    Garmin MobliPC have the same settings and maps as MobileXT
    The maps goes in GarminMobilePC folder (this folder is created during the installation)
