We just got back from the black hills and it was very nice to have it. If you turned on a trail it would then tell you the trail number. We just went without worry about getting back home when time came to go home we just put in our camp ground and it took us back. It gives plenty warning for turning corners and highlights trails and you can read it during daylight hours. Kinda speedy but hopefully it will last, I also wish you could plug it into the power outlet that the machines have. I have a Honda and the battery is under left fender lots of wire to run to get by rear view mirror. Its a game changer! Steve
