GMC 2009 Yukon XL Owner's Manual page 317

Problem
The remote control does
not work.
After stopping the player,
I push Play but sometimes
the DVD starts where I left
off and sometimes at the
beginning.
The auxiliary source is
running but there is no
picture or sound.
Recommended Action
Check to make sure there
is no obstruction between
the remote control and the
transmitter window.
Check the batteries to
make sure they are not
dead or installed
incorrectly.
If the stop button was
pressed one time, the
DVD player resumes
playing where the DVD
was stopped. If the stop
button was pressed
two times the DVD player
begins to play from the
beginning of the DVD.
Check that the RSE video
screen is in the auxiliary
source mode.
Check the auxiliary input
connections at both
devices.
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.
Recommended Action
Check for obstructions,
low batteries, reception
range, and interference
from cellular telephone
towers or by using a
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.
