When updating my Tomtom GO 620 the text came up: enter new map. Have one of 64 GB purchased. How do I put that card in that device? There is only a very narrow slit at the top.

When I want to enter a route it says: no map present or something like that.

    Welcome to the site...
    Tomtom Video... Where to find the memory card slot on your device....

    Tomtom devices use a Class 10 Micro SDHC Memory Card size 16GB or 32GB (Max)
    The Memory card is 1st formatted Fat32 then formatted in the Tomtom device to a secure Tomtom propriety format for Maps....
    Note... Windows won’t format SD cards larger than 32GB using FAT32.
    However, it is possible using third party tools, but Memory cards larger than 32GB are not officially supported by Tomtom....
