Problem Sometimes the wireless headphone audio cuts out or buzzes. I lost the remote and/or the headphones. The DVD is playing, but there is no picture or sound. The audio/video skips or jumps. The audio from the radio for the Radio with Six-Disc CD and XM™ has taken over the audio from the DVD or CD when using the wired headphones. Recommended Action Check for obstructions, low batteries, reception range, and interference from cellular telephone towers or by using your cellular telephone in the vehicle. Check that the headphones are facing the front of the vehicle. See your dealer for assistance. Check that the DVD player is in DVD mode. The DVD or CD could be dirty, scratched, or damaged. The RSE is working correctly. Use the wireless headphones or have the front seat passengers listen to another audio source.
