The street names on the maps are in a small font and are hard to read, especially when driving. Sometimes the street names are right on top of the street.When I travel with someone who has built-in GPS in their vehicle, the maps are easy to see. Street names legible. Also the numbered highways are indicated just like the highway number signs. Rather than text "State Highway 33" the familiar shield should be on the map.With the SSD cards, there is plenty of room for alternate maps.
