Was out of town for a few days (and kept checking our MS while away) - the last day or two, we couldn't connect to the car. Got home, car seemed fine but still couldn't connect with the app. Wife got in to go to work, and kept getting 'no connectivity' errors and saw no bars.. the 3G radio seemed dead.
The good news is, rebooting the display fixed it.. but not sure why the radio seemed to 'sleep'.
Just a heads-up if anyone else runs into this.
