Radio Messages Calibration Error: The audio system has been calibrated for your vehicle from the factory. If Calibration Error appears on the display, it means that the radio has not been configured properly for your vehicle and it must be returned to your dealer for service. Locked: This message is displayed when the THEFTLOCK® system has locked up the radio. Take the vehicle to your dealer for service. If any error occurs repeatedly or if an error cannot be corrected, contact your dealer. Playing a CD (In Either the DVD or CD Slot) Insert a CD partway into the slot, label side up. The player will pull it in and the CD should begin playing (loading a disc into the system, depending on media type and format ranges from 5 to 20 seconds for a CD, and up to 30 seconds for a DVD to begin playing). If the ignition or radio is turned off, with a CD in the player, it will stay in the player. When the ignition or radio is turned on, the CD will start playing where it stopped, if it was the last selected audio source. The CD is controlled by the buttons on the radio faceplate or by the RSA unit. See Rear Seat Audio (RSA) on page 332 for more information. The DVD/CD decks, (upper slot is the DVD deck and the lower slot is the CD deck) of the radio are compatible with most audio CDs, CD-R, CD-RW, and MP3s. When a CD is inserted, the text label DVD or CD symbol will appear on the left side of the radio display. As each new track starts to play, the track number will appear on the display.
