running but there is no
picture or sound.
Sometimes the wireless
headphone audio cuts
out or buzzes.
I lost the remote and/or
the headphones.

Recommended Action
Check that the RSE

Check the auxiliary input
connections at both
devices.
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 on
correctly using the
L (left) and R (right) on
the headphones.
See your dealer/retailer
for assistance.
Check that the RSE video
screen is sourced to the
DVD player.
