Ejecting a Disc
Press the eject button on the radio to eject the
disc. If a disc is ejected from the radio, but
not removed, the radio will reload the disc after a
short period of time. The disc will be stored in
the radio. The radio will not resume play of the disc
automatically. If the RSA system is sourced to
the DVD, the movie when reloaded into the DVD
player will begin to play again. In case loading
and reading of a DVD or CD cannot be completed
(unknown format, etc.), and the disc fails to
eject, press and hold the DVD Eject button more
than 5 seconds to force the disc to eject.
DVD Radio Error Messages
Player Error: This message is displayed when
there are disc load or eject problems.
Disc Format Error: This message will be
displayed, if the disc is inserted with the disc label
wrong side up, or if the disc is damaged.
Disc Region Error: This message will be
displayed, if the disc is not from a correct region.
No Disc Inserted: This message will be
displayed, if no disc is present when the EJECT or
DVD/CD AUX button is pressed on the radio.
Using the Auxiliary Input Jack(s)
Your radio system has an auxiliary input jack
located on the lower right side of the faceplate. This
is not an audio output; do not plug the headphone
set into the front auxiliary input jack. You can
however, connect an external audio device such as
an iPod, laptop computer, MP3 player, CD player,
or cassette tape player, etc. to the auxiliary input
jack for use as another source for audio listening.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio's front auxiliary
input jack. When a device is connected, the radio
automatically begins playing audio from the
device over the vehicle speakers.
