Mapa de USA

Buenas tardes!!!!! Quisiera el mapa de estados unidos para mi gps tomtom xxl 540 classic. El gps viene con mapa de argentina y uruguay. Sinceramente no entiendo mucho del tema sobre como borrar mapas y cargarle nuevos o si viene el mapa de estados unidos para mi gps. Espero su respuesta. Muchas gracias

El bootloader del gps me indica que tiene una memoria de 64 MB y no tiene ranura para memoria externa

Los datos del gps son:
