Your GPS probably came with a preloaded map program, but it might leave much to be desired. The following list will show you several software programs you can download that will provide free maps for your GPS device.
USA Photo Maps
If you are seeking GPS maps for United States addresses, USA Photo Maps has plenty to offer. This free software program creates maps using aerial photo and topo map data, allowing you to scroll, zoom and view latitude and longitude. You can search by and see landmarks, view elevations, and add your own routes, text or waypoints to the map. The maps are easy to transfer between your computer and your GPS device. In addition, you can view your current GPS location.
Along with a complete download, updates are available on the USA Photo Maps website. There is also a link to an active Yahoo Groups forum devoted to the software, where you can ask questions and discuss how you use the maps.
