Hi Kglunt.
To clarify, the nuvi 2597LMT does not come with a micro SD card in the box. The device does have internal memory, however, a micro SD card can be inserted into the device to add memory, if necessary for map updates, storing additional maps, waypoints, and routes.
We typically recommend using an 8 GB card for storing map updates. Depending on the space needed and what is being stored, the device is compatible with smaller capacity cards such as 2 GB, up to a maximum of 32 GB micro SD card. Thanks for asking. *CG
