I finally used my GPS again last summer to find a trail head that I've only been to once or maybe twice a long time ago and had the location on my GPS. I only remembered that we had to go somewhere west or northwest. My friend drove my truck while I navigated. It was a big pain in the butt going back and forth from north to west until we finally found the right road but at least we found it.

P.S. When I used the GPS on the ATV I plugged it into my ATV's 12 volt cigarette lighter socket. If I didn't my batteries would only last for a couple of rides in the winter. Summer wasn't that bad.

I am going to mount my phone to track how far, speed and elevation.

What GPS?
 

Mine says "silva" and "Us Geological Survey"
