Using the TeleType Pro "Load in View" feature you will be able to display maps as desired. Maps are downloaded via the internet, however you may download and rename files so that multiple files can be displayed simultaneously.

It is possible to load street maps over the topographic image. Right click the map screen and load street or highway maps as desired.
