Ejecting a Disc Press the Zbutton on the radio to eject the disc. If a disc is ejected from the radio, but not removed, the radio reloads the disc after a short period of time. The disc is stored in the radio. The radio does not resume play of the disc automatically. If the RSA system is sourced to the DVD, the movie when reloaded into the DVD player begins 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 Z button more than five seconds to force the disc to eject. Using the Auxiliary Input Jack The 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. An external audio device such as an iPod, laptop computer, MP3 player, CD player, etc. can be connected to the auxiliary input jack for use as another source for audio listening. Drivers are encouraged to set up any auxiliary device while the vehicle is in PARK (P). See Defensive Driving on page 4-2 for more information on driver distraction. 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, press the radio CD/AUX button to begin playing audio from the device over the vehicle speakers. For optimal sound quality, increase the portable audio device's volume to the loudest level. It is always best to power your portable audio device through its own battery while playing.
