Now after 2.5 months of using Sync with the same ipod continuously plugged in for most of that time, Sync has started the perpetual indexing problem. Turning the stereo off, turning car off etc no cure. At first it was even telling me "index full some songs may not be available" as soon as I started the car (2 days ago) but it won't play anything. Today I tried connecting my iPhone by USB (it has music and I've played music via Sync on it before successfully) and it still said indexing... plugged the iPod back in and same thing.
It does know that the device was unplugged or new one plugged in, this seems to be a memory leak or other Sync OS problem.
Is there any cure other than pulling the fuzes?
