I live in NC, and while I live near Charlotte, I occasionally travel to Pisgah National Forest or Dupont to mountain bike. Inevitably, whenever I try to use my Edge 530, and specifically the Trailforks mapping, it won't work. I usually try to pick my route in advance, and I make the route a "favorite" before I leave my house, and everything is fine. When I get to the trails, I receive an Error Code 400 message and I can't get the map (or Trailforks on the Edge 530) to work.
What is Error Code 400? Is there something I'm doing wrong? For what it's worth, it also seems like I have cell phone service.
