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. An external audio device such as an iPod, laptop computer, MP3 player, CD changer, 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. CD/AUX (CD/Auxiliary): Press to play a CD while 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, the message No Aux Input Device displays. Using an MP3 MP3 CD-R or CD-RW Disc The radio plays MP3 files that were recorded on a CD-R or CD-RW disc. The files can be recorded with the following fixed bit rates: 32 kbps, 40 kbps, 56 kbps, 64 kbps, 80 kbps, 96 kbps, 112 kbps, 128 kbps, 160 kbps, 192 kbps, 224 kbps, 256 kbps, and 320 kbps or a variable bit rate. Song title, artist name, and album are available for display by the radio when recorded using ID3 tags version 1 and 2. O (Power/Volume): Turn clockwise or counterclockwise to increase or decrease the volume of the portable player. You might need to do additional volume adjustments from the portable device if the volume is not loud or soft enough. BAND: Press to listen to the radio while a portable audio device is playing. The portable audio device continues playing, so you might want to stop it or turn it off. Compressed Audio The radio also plays discs that contain both uncompressed CD audio (.CDA files) and MP3 files. By default the radio shows the MP3 label on the left side of the screen but plays both file formats in the order in which they were recorded to the disc. 3-77
