I know about the se navcore's but i have been told that there is something called a me navcore making the rounds? Can someone tell me if this is true and if so what would be the differance between the 2.
ME stands for "Mireille Edition". It is conceived by a person called "DarkMireille" who is present on other forums. Just do a Google search for the name in combination with navcore Start 8.544, since it is on the Tomtom Start/Ease that he/she started working out the idea of the ME version.
The approach is quite different from that of TTUser in that the ME edition in essence takes apart the ttsystem file and uses the components separately. Especially Tomtom Rider users who are looking for newer navcores that work with their BT earplugs seem to be enthousiastic about it.
He/she also started tinkering with 9.051 but afaik 8.544 is favourite.
