My old version would not get past the update 18.104.22.1687 and so I could not sign into it. So I uninstalled it hoping to load a later version however I cannot find the download for it. Has it been superseded as I cannot find anything about it and the TomTOm tutorial that directs you to "tomtom.com/home" flashes for a brief second before moving you onto a discussion page. Without Home my computer cannot 'see' my device. Any suggestions welcome.
