el mapa es western central Europe y está bastante anticuado a juzgar por numerosas calles de mi pueblo que no vienen y existen ya hace bastantes años, y otras cambiadas de sentido.
No sé si estas atualizaciones que poneis aqui para los mapas europa e iberia me sirven a mi o me tengo que descargar esos mapas completos. Como veis ando perdido y el tomtom no me guia .
Gracias de antemano por vuestra ayuda
