Ok, I have a TOMTOM One 3rd series. I really love it. Me and my gf use it all the time when we take trips. Well this september we are going to Rodanthe, NC. However, whenever i try to use it, it takes me through Washington DC. Which I know will be terrible, alot of other maps dont go this route. Whenever i try to do an alternative route all i get are road choices. Any ideas?
