March 31, 2017. We are pleased to announce the availability of an addon that has been highly requested by BackCountry Navigator users. As of this writing, it is available for $15.99 in Menu->Purchasing Addons in the paid version of BackCountry Navigator.
Motor Vehicle Use Maps (MVUM) are created by the US Forest Service. They depict Forest Service roads and trails that are designated for motor vehicle use.
This shows an overview of the area covered by this data. You can also see that here:.

Like many addons that are overlays, you can choose (and need to choose) what map is displayed under it. It can be used with any of our map sources including maps from OpenAndroMaps.org/en, which can be downloaded by state.
You can select trails /roads using the button at left and choose one of them for additional attributes.
When you choose Menu->Purchasing Addons, you will now see a new category just for MVUM:
