Actualizar los mapas del TomTom ONE

Hola soy Pito 56 y quisiera actualizar mi TomTom One v3 y no tengo ni remota idea de como hacerlo. Hace varios años los actualizaba yo pero hoy en día se me ha perdido todos los datos. Os agradecería que me ayudaseis y me orientarais un poco para saber como se hace porque necesito poner los mapas de Escocia. Daros las gracias porque os lo habéis currado mucho.

Perdón por lo de los tres hilos, pero no me aclaraba publicando
porque me daba error. Gracias
