I've recently bought a 2011 laguna with built in satnav.
I ve taken out the SD card and plugged it into my Mac and downloaded Tomtom home but still can't find a way to update the SD card.

    Hi Jamo2565

    Welcome to the community:)

    If you are experiencing an error with the card in your car, you may need to initialise it. This in effect checks the software on your card and makes sure the files are not corrupted.

    Please try the steps below:

    1. In your car, insert your SD card into your Carminat TomTom.
    2. Turn on your cars ignition and then switch on your Carminat TomTom.
    3. Carminat TomTom initialises your new SD card. This takes at least 30 seconds. Do not turn off your cars engine while the Carminat TomTom indicates that it is busy.
    4. Switch off the Carminat TomTom and then turn off your cars ignition. Wait another 5 seconds then remove the SD card.
    5. Try again to connect your SD card to TomTom HOME on your computer.

    Check if this will help. You can get in touch with our customer service should you need any further assistance with this.
