    help Help with Maps on Garmin KNA-G420AT

    Dear ALL,\I have serious issue with my Navigation on the car, it keep saying failed to load the maps

    My Navigation is Garmin KNA-G420AT based on Kenwood DDX 7039 and I am trying to upgrade my maps and lost the old one and I am now in big lose.

    I need Middle East Garmin 2012.40 or latest one and I need to ask how to upload it on the same device above.

    last thing do I have an option to upgrade the map graphics like the new one or to support 3D or Cameras or anything

    I will deeply appreciate help on this as my wife cannot drive the car since a week on UAE.

    By the way I have used SD 2 GB which is not the original because the old one was 120 MB which is not enough for the new maps

    Do you update FW on your KNA to FW 4.20?

    This is in new FW 4.20:

    Changes made from version 4.10 to 4.20:

    Corrected new ICAO list overflow issue.
    Added support for maps greater than 2GB in size.
    Fixed stability issues when parsing bad weather county warning file.
    Updated to allow locking maps to UID from external media.

    Changes made from version 4.00 to 4.10:

    Added support for high-density SD cards to handle future map updates.

    I have a KNA-G430TH and cannot for the life of me get the 4.20 update to work.. It just sits there forever with "Transferring data.." on the screen after I choose yes to update the software .. most most frustrating.. left it for 30mins and still no luck .. I am stuck on v2.80 erk

    Try this KNA-G430 Singapore/Malaysia, Austrailia.

    [Only registered and activated users can see links. ]

    Installation Instructions


    1. Create a 'garmin' folder on an SD data card (must be at least 16mb space available on the card).
    2. Download the appropriate self-extracting archive file onto your hard drive.
    3. Run the downloaded executable file.
    4. Click on Browse and select the SD card reader in the list, then select the 'garmin' folder.
    5. Click Unzip to save the files onto the 'garmin' directory on the SD card.
    6. Wait for the message that the update was unzipped successfully and close the updater.
    7. Safely remove SD card from PC.
    8. Make certain Hideaway Navigation System is off.
    9. Insert SD card into Hideaway Navigation System. If there is already a card there, temporarily remove it.
    10. Turn on Hideaway Navigation system.
    11. Your Hideaway Navigation System will ask if you would like to update software. Answer 'Yes'.
    12. The update will begin. Do not power off unit while the update is in progress. When finished you can verify the update by checking the version number in Menu->Settings->About->Software.
    13. Remove SD card.


    The SD card no more than 2GB, I recommend 1GB or less and formatted in FAT32
