2007 - Intersection Finder for Specific City

So I love my 2007 Prius nav system and its ability to find the nearest highway entrance (something I think should be on all car nav systems), but I am having a problem with the street intersection finder. Does anyone know if there is a way to specify what city you want to look in before naming the intersecting streets?

I had this problem looking for a way to get to Broadway and Frankiln in San Francisco, but when the system searchs by street name before the city, there are about 70 "Broadway"s in California and Oregon (region US2) and no apparant way to distinguish them until you complete the route guidance. Has anyone found a way around this?
