i have a qestion in regards to my tomtom one first off i have used the search feature! with some results and other results seem to just be links to links that being said, what is the best way to be sure that my tomtom is uptodate...tomtom home says it is but im not sure. also in regards to maps is there a way to be sure my maps are uptodate, if not are maps strictly a purchase item or can it be done through a download?
