Tal vez ya estaba actualizado. Pero aún así no tuve acceso a ningún link para llevar acabo una futura actualización al scaner. Es ese uno de los motivos de mi retorno. Buscaré algo más completo No importando un mayor pago. Calidad, material , función es bueno . Solo ajusten el link de actualización para dar may confianza para la cargar mayor modelos de autos. Necesite selecciónar entre varios modelos de autos ya cargados en el scaner para ver cuál tomaba la lectura del auto. No siempre era el modelo específico que buscaba. Ejemplo Ford solo una opción y pocas opciones de años y modelos ... show more
