Hello, The size of the micro SD card is 10GB and during the update to the reception of the device, after 3:30 waiting, it tells me to put a micro SD card of higher capacity but n has no access to the location of the memory card, so you have to choose a map of Central Europe (without the 45 countries announced) Dailleurs I am amazed that there is the US on my Garmin 3590 LMT I do not understand no.
