I'm just curious. Does anyone know what switch would replace the blank space next to the Traction Control Switch (on the right side) . I had seen the BlueTooth Switch in the third position to the right, but what would go in the second position? There is also a blank space next to the Cruise Control On/Off Switch (on the right side) mounted on the steering wheel. Any idea what switch would go there? Are there other options available for which these blank spaces would be utilized?
