No responde la pantalla de TT GO530

Hola a todos.
Me han regalado un tomtom go530 porque no funciona la pantalla, es decir, la pantalla se enciende y se ve perfecta, pero no responde al táctil en ninguna posición de la pantalla (no es que esté "desviada", es que parece que no es táctil).
Como me vengo arriba con facilidad he leído un hilo de Orni y he "recuperado" el equipo por completo, borrando toda la información y cargando datos nuevos, pero no ha resultado.
¿a alguien se le ocurre algo? ¿puede ser que falle algún archivo? La pantalla se ve bien, nítida y sin golpes.
Los datos son:
