The Tomtom is great for navigating but I find , as a driver, the text is way to small to view street names at a glance. If you have a front seat passenger, they can study the screen without worry. You can put in larger micro SD cards so there is a lot of room to have more than one version of a map available. Anyone with built-in GPS can attest to the ease of reading street names. They usually appear in a bubble pointing to the street. They also have highway numbers appearing just as the signs are on the road.
