Ah, OK, I didn't remember right. I did have a 460W that had traffic and could have the providers deactivated. The 855 and 765 cannot have deactivated any provider.
Both have lifetime TT and Navteq.
On 855 I have Total Traffic station listed, on 760 I have the Navteq ones. The others are listed "not named". I cannot tell if they are used or not.
