My telematics unit was not transmitting properly until I did the reprogramming. It would communicate with myfordmobile (website and app) for a couple weeks, then fail to communicate until it was reset. After the reprogramming, it's been online 99% of the time. I had it reprogrammed since the beginning of May. There was a small quirk from the reprogramming that's probably limited to my car. After it was reprogrammed, every time I started the car, it would try to "navigate home" on the built-in navi no matter what the settings were when I turned off the car. I fixed that by deleting the home address, then adding it back in.
