I need to move my TomTom software from my old, dying computer to my new computer. (N.B. : I have 'legacy device' which is no longer supported by phone, email or chat, TomTom tells me.) My original CD is four years old and I have since added western European maps and updated it countless times. How can I get the updated software (2.8.3.2499) into my new computer. Many thanks!
