Sorry, but downloadable maps are no longer supported. In the past, downloads were available in Mobile Atlas Creator format which involved installing an app and also the Java Development Kit from Oracle. This whole process was awkward, confusing and had compatibility issues. Garmin also limits this kind of map to a very small coverage area, such that they aren’t very useful. Mobile Atlas Creator and this type of map are no longer supported by boydsmaps.
Access over 150 maps and use your phone as a GPS with the free boydsmaps mobile web app, which will soon be upgraded with many powerful new features. When the upgrade is complete, a new universal boydsmaps app for both computers and mobile devices will replace boydsmaps online.
