So I have been interested in updating my TT720 to include the Voice Address Input as I have seen that it is offered on the new 720s. So I was unable to do the directions posted by another user because my latest map guarantee ran out and I decided to give ol TomTom a call. They acknowledged that later model 720s had this function and that a firmware update would be coming up within the next two weeks to allow the older models (like me) to have that same technology via a simple update on TomTom Home. Hope this helps anybody who isn't able to get that new map like me and use the 'hack'. Let me know what you guys think
