The device will work out of the box without adding a micro SD card. However as future map updates are released they may have so much new information that it won’t fit on the device's internal memory, at that point a micro SD card can be used to expand the memory. This model supports microSD cards from 8 GB to 32 GB, with speed ratings up to class 10 (including unmarked cards).
Sorry, there was a problem. Please try again later.The unit comes with enough internal memory for all US and Canada maps. However, you can increase memory with a micro SD card, up to 32 gb, if desired. The unit works fine right out of the box without a micro SD card.
Sorry, there was a problem. Please try again later.It holds all the maps that I am currently interested in (US, CANADA). As to the sd card, they are so cheap, I would get the one with the greatest capacity. Just make sure you get the adapter for use with a regular computer reader.
Sorry, there was a problem. Please try again later.No sd card necessary, this system is built to handle it.
