Since a week my built in navigation Tomtom NB1 in Mazda CX5 isnt working anymore. It doesnt start anymore when I start the car engine. Also when I press the NAV buttons in the car it doesnt start.
The other functions like radio, settings, phone are still normall working. We had freezing temperatures in the Netherlands the last few days. Is it possible that the navigation is damaged by the cold weather?

Maybe the cardreader is broke?

Is there anyone who can give me the solution?

    Hi @Peter342454
    Welcome to the community!
    If you connect the SD card to the computer and open TomTom HOME software application does it recognize the card and the installed contents?

    Thanks, Vikram
