just be sure that "Logic 7" is selected in the settings menu. We had our kids in the third row and they complained that the speakers were not on. I tried changing the sound to all rear and still nothing. Went to the dealer only to learn that if the setting is "Stereo" then only the front & rear speakers work. If set to "Logic 7" then all 3 rows of speakers have sound. Hopefully this saves someone a trip to the dealer.
