Well, I just had my 3rd (maybe 4th) reboot since the update.
I had to do a master reset because my bluetooth audio controls went away. I called the help phone number and the lady recommended a master reset. I explained to her of the problems that I'm still having and that my dealer does not know much about this system. I also asked if they are looking at a patch in the near future, and she told me they are working on one and they do have quite a few known issues, but there is no ETA for the patch yet.
I also told her of my buttons turning red problem. THis has happened twice to me, all buttons on screen turn a bright red, and the only fix is to press each button or do a master reset.
Anyone else had the "red button" problem?
