I noticed on Thursday morning a notice across my radio screen stating something about an update but it needed a better signal. I didn't pay much mind as I had to 'hit the road' for a road trip. While driving I never saw this notice pop up but I did notice a change to the HOME button screen, it was not available. Usually the Home button shows a small map and the radio station playing. I could not get that screen to pop up as the HOME button only kept cycling through the other button options. It simply would change the screen mode from NAV to Comfort to Apps so on and so forth. Just putting this oddity out there to see if anyone else has the same thing going on with their HOME button.
