I use Avensa Maps on my cellphone. Avensa is GPS so you do not need cell service. All maps that they offer are on this system. Put the same RAM MOUNT as I use in my Vehicle. In California we have CTUC California Trail Users Coalition. A series of OHV and National Forest Maps with all Ohv roads and trails marked. When I bought the series there were 16 separate Maps you can download, or just the area you will be riding. It shows a dot as to your position on the maps. I have been using map and compass for 50 years but this is the best.
