Do you have the XL version with the 3rd row seat? Similar thing happened when I first bought my EXT, the driver's control knob next to the gear shift got bumped into the R position, and the 2nd row seat controls for the rear system were "on".
Yes. Its an XL with a 3rd row seat. Thats what I initially thought when she told me, but when I checked, it was not in the R position and the rear controls are off.
