Using the Auxiliary Input Jack 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. 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. BAND: Press to listen to the radio when a portable audio device is playing. The portable audio device continues playing, so you might want to stop it or turn it off. CD/AUX (CD/Auxiliary): Press to play a CD when a portable audio device is playing. Press again and the system begins playing audio from the connected portable audio player. If a portable audio player is not connected, "No Input Device Found" displays. DVD/CD AUX (DVD/CD/Auxiliary): Press to cycle through DVD, CD, or Auxiliary when listening to the radio. The DVD/CD text label and a message showing track or chapter number displays when a disc is in either slot. Press again and the system automatically searches for an auxiliary input device, such as a portable audio player. If a portable audio player is not connected, "No Aux Input Device" displays. If a disc is in both the DVD slot and the CD slot the DVD/CD AUX button cycles between the two sources and not indicate "No Aux Input Device". If a front auxiliary device is connected, the DVD/CD AUX button cycles through all available options, such as: DVD slot, CD slot, Front Auxiliary, and Rear Auxiliary (if available). See "Using the Auxiliary Input Jack(s)" later in this section, or "Audio/Video (A/V) Jacks" under, Rear Seat Entertainment (RSE) System on page 3-115 for more information. O (Power/Volume): Turn clockwise or counterclockwise to increase or decrease the volume of the portable player. Additional volume adjustments might have to be made from the portable device if the volume is not loud or soft enough. 3-103
