About every minute or so, there is a 3-4 second pause that occurs in the sound from the stereo and the dashboard computer controls, that is, the controls become unresponsive for the elapsed time (changing the radio station with the steering wheel, or changing MPG display or whatever). Any ideas on what is happening?
