While driving to work after lunch I noticed that my presets had disappeared on the Sync home screen. It just showed six empty boxes. It still remembered them because I was able to scroll through them with the steering wheel control, they just didn't show up on the sync home screen. I tried to reset the presets and it still didn't show, restarted the car a couple times, and let it sit for an hour while off to see if it would come back up when restarted. No luck. I did a master reset on the system and it is working now, but I would like to know if this has happened to anyone else and if they had an easier way to fix it. Seems to me that a master reset is a little overkill just to make the buttons show up correctly again.
