2007 model for me, same problem. I prefer darker screen, set it at minimum brightness and following day back to mid setting. I have the latest firmware and also too have tried countless memory sets with and without the fob. I too also start the vehicle in garage, auto headlights do activate. Perhaps there might be a connection. I would surely like a fix for this. In a twisted sense of relief it is slightly nice to know I am not the only with this problem.
