I am getting a popping noise from the speakers. It has happened twice - once when my phone was connected and once when there was nothing connected at all. The popping noise continues even after the car is shut off, after the door has been opened and the radio is off. I took it to the dealer, but they have no idea of what it is. I can never get it to the dealer while it is happening. I saw some older posts with what sounds like the same issue, but still saw no resolution for the issue. Has anything been discovered recently?
