Problem I lost the remote control and/or the headphones. Sometimes the wireless headphone audio cuts out or buzzes for a moment, then it comes back. Recommended Action Contact your GM dealer for assistance. This could be caused by interference from cell towers or by using the cellular telephone or other radio transmitter devices in the vehicle. In severe or extreme temperatures the DVD system might not be operable. Temperatures below −4°F (−20°C) or above 140°F (60°C) could damage the DVD system. Operate the DVD system under normal or comfortable cabin temperature ranges. See your GM dealer if the problem persists. Problem The wireless headphones have audio distortion.
