Unknown Navcore version

When I open MyDrive Connect, I get the message “Unknown Navcore Version”.
I have no device connected and I have uninstalled and re-installed the MyDrive Connect software numerous times, including many occasions with TomTom Support Staff assistance.
This error message first occurred when my device was identified as defective.
Does this persistent error condition attached to My Account on your database mean that I will never be able to use a TomTom device in future?

    Maybe some odd data being left behind from a standard un-install ???

    On the rare occasions I have a problem with myDrive Connect
    I Delete MyDrive Connect using the free version of Revo Uninstaller
    If you're using a Windows PC... Delete MyDrive Connect using the free version of Revo Uninstaller
    (Important... Do not have your device connected to your PC when you reinstall MyDrive Connect)

    If you're using a Mac... Surely there must be a Deep Clean Un-installer Program available for a Mac ???

    Download & install the free version of Revo Uninstaller
    Revo first uninstalls the Program... Then scans and removes all of the left over files a normal uninstall leaves behind
    Video using the Revo Uninstaller
    The Free & Pro Versions use the same process....

    (1)... Uninstall MyDrive Connect Using the Revo Uninstaller
    (2)... Clear your browsers cache (Optional, but I find it helps)
    (3)... Restart your PC (Not Turn Off & Turn On again)
    Reinstall MyDrive Connnect (Important... Without your device connected)
    Connect & Turn on your device... Login to MyDrive Connect...

    Hi @Rx54eub1

    Welcome to the Community! I've checked your device details and found that your device neither has the maps installed nor the application on it. I've now pushed the application download for your device, Please follow the steps below to apply these changes:

    This time please try using the Wired (Ethernet) connection since WiFi may work but can be slow causing a Time-Out
    • If your navigation device is connected to the computer, disconnect it.
    • Right-click the MyDrive Connect icon in the Windows notification area or Apple menu bar and then select Cogwheel > Settings.
    • Select the tab Downloads.
    • Click Empty download folder. (Ignore if it's greyed out)
    • Click Save settings.
    • Enable the option 'Download updates on my computer'
    • Click the MyDrive Connect icon in the Windows notification area or Apple menu bar and then click Quit> Start MyDrive Connect.
    • The device will say 'updating' and then reboot automatically

    Even if the download or installation appears to stop or freeze, keep it connected for 4 hours, then check if the download has been completed. Best order to update 1 by 1: (if offered)
    • QuickGPSfix / Navcore (if these updates are offered, they cannot be de-selected)
    • Map
    • Speed Cameras
    • Voices
    • Mapshare update (recommended to update last)

    Regards, lampard

    I also have the same error code. On checking my Go5200 system it says the following:
    Application version 19.201.0010.411 (0) (27/09/2019)
    Installed Maps: UK & ROI v 1045.10014 13 months old (release 01/2020)
    Free space: 12.12 GB Internal memory
    Data connection: USB
    GPRS statsu: Disconnected
    GPRS Model: 16.01.202

    When I go to Updates and New Items, it says "Your TomTom GO 5200 is up to date!

    Is it up to date and why do I get the error message on My Drive of “Unknown Navcore Version”.

    Hi @Glosterboy
    Welcome to the community! My Team is pushed a recovery script to fix any bugs in the application.
    Just do a soft reset and check for updates in MyDrive Connect.
    The device might reboot during the process.

    Thanks, Vikram
