The Polaris Ride Command app works with both android and apple and it is free. Any android tablet or I-pad with gps should work no cell service needed. It has roads and trails on it also can track and store your track. Should have most major trail systems in it and also tells you parking locations. I had a few garmins in the past and the screen was so small and no color I decided to switch. Way cheaper to buy a tablet and use the free Polaris ride command app in my opinion. Down load the app on you phone and try its free might as well check it out before you go spend money on something.
