Hi, hope someone can give me some advice. I have a TomTom OneXL which is a few years old now but has always worked well until another member of this household tried using the sd card from the device in a digital camera which corrupted the card. There is nothing on the card now and nothing on the device . I'd like to continue using this sat nav so I was considering buying a new sd card with maps for the Republic of Ireland and the UK (which is all I'd ever need anyway). But is that enough, do I need to reinstall some sort of operating system or applications, voices etc to the sat nav in order for it to work. Many thanks for viewing.
