Audio/Video (A/V) Jacks
The A/V jacks located on the rear of the floor
console, allow audio or video signals to be
connected from an auxiliary device such as a
camcorder or a video game unit to the RSE
system. Adapter connectors or cables may be
required to connect the auxiliary device to the
A/V jacks. Refer to the manufacturer's instructions
for proper usage.

The A/V jacks are color coded to match typical
home entertainment system equipment. The yellow
jack (A) is for the video input. The white jack (B)
is for the left audio input. The red jack (C) is for
the right audio input.
Power for auxiliary devices is not supplied by the
radio system.
To use the auxiliary inputs of the RSE system,
connect an external auxiliary device to the
color-coded A/V jacks and turn both the auxiliary
device and the video screen power on. If the video
screen is in the DVD player mode, pressing the
AUX (auxiliary) button on the remote control
switches the video screen from the DVD player
mode to the auxiliary device. The radio can listen
to the audio of the connected auxiliary device
by sourcing to auxiliary. See Radio with CD and
DVD on page 278 for more information.
