GPS for Showing Real Estate

About a year ago, I bought a Magellan Maestro 4250. What a time saver that is! I enter the addresses for the homes I am going to show that day, press the button for "Optimize", and presto.....the Magellan arranges the addresses in an organized sequence for showing. This cuts down my preparation time and once I am on the road, the Magellan leaves me free to talk to clients about the homes we are seeing without having to search for the directions.
