We took delivery of my wife's 2013 HyTi on July 12. We use an 8000+ song iPod classic with it. For some inexplicable reason, Sync is constantly "indexing it." I thought that it would take a couple of weeks of driving for Ford to build up an index and a command list, but after that, provided none of the songs changed, it wouldn't need to keep indexing. That hasn't turned out to be the case. It seems it builds an index every time we start the car, and with that many songs, you have to drive for a couple of hours before it completes. I would think it would only need to do that when it found new files. Is anyone using an iPod with a large library? Are you seeing the same "Indexing" or "building commands" prompts every time you start the car? Will this ever subside?Thanks!
