It's also not a local problem. Mine went down Thursday night, 24 Aug. On Sat I started a 3600 mile road trip. The problem exists from CO to Philadelphia.
A few times a thumb wheel reset did the trick, but it was not consistent. I found that if I switched to radio for about 15 minutes, then went back to Streaming, it would come up, and stay up until I shut down the car. On restart, I was back to "Loading Error"
