Something went wrong when I was updating my satnav. Now it says no maps found, and My Drive Connect says
Unknown Navcore Version. I've tried uninstalling and reinstalling twice but no luck.

    Hi @Quin

    Look back here tomorrow to see what @VikramK has to say after he has reviewed the Logs for your unit to see what has happened.

    Hi @Quin
    Welcome to the community! My team has created a script that will do a fresh installation of the firmware on your TomTom.
    Just follow the steps below-
    1. Quit/Exit MyDrive Connect application.
    2. Delete the HOME3 folder located at-

    Users\Your username\Library\Application Support\TomTom\
    Windows OS
    C:\Users\"Your username"\AppData\Local\TomTom

    3. Open MyDrive Connect
    4. Connect the device and check for updates.

    Did as you suggested but issue still remains. The HOME3 folder always reappears as I open MyDrive Connect.
