Infotainment System / Audio Players / Playing a CD (in Either the DVD or CD Slot)

If the ignition or radio is turned off with a CD in the player, it stays in the player. When the ignition or radio is turned on, the CD starts 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) System on page 7‑48 for more information. The DVD/CD decks (the upper slot is the DVD deck and the lower slot is the CD deck) of the radio are compatible with most audio CDs, CD-Rs, CD-RWs, and MP3s.

When a CD is inserted, the text tab DVD or CD symbol displays on the left side of the radio display. As each new track starts to play, the track number displays.

The CD player can play the smaller 8 cm (3 in) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

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 does 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” in Auxiliary Devices on page 7‑33 or “Audio/ Video (A/V) Jacks” under Rear Seat Entertainment (RSE) System on page 7‑38 for more information.

The DVD player only reads uncompressed audio and ignores MP3/WMA files on a mixed mode disc.

The CD player reads both uncompressed audio and MP3/ WMA files on a mixed mode disc.

Uncompressd audio is played before MP3/WMA files. Press the CAT (category) button to toggle between uncompressed audio and MP3/WMA files.

CD-R or CD-RW Supported File and Folder Structure

The DVD player supports:
• Up to 255 folders.
• Up to eight folders in depth.
• Up to 15 playlists.
• Up to 40 sessions.
• Playlists with an .m3u or .wpl extension.
• Files with an .mp3, .wma, or .cda file extension.

The CD player supports:
• Up to 512 files and folders.
• Up to 8 folders in depth.
• Playlists with an .m3u or .wpl extension.
• Files with an .mp3, .wma, or .cda file extension.

Root Directory

The root directory of the disc is treated as a folder. If the root directory has compressed audio files, the directory displays as F1 ROOT on the radio.

If a disc contains both uncompressed CD audio and MP3/ WMA files, a folder under the root directory called CD accesses all of the CD audio tracks on the disc.

Empty Folder

Folders that do not contain files are skipped, and the player advances to the next folder that contains files.

No Folder

When the disc contains only compressed files, the files are located under the root folder. The next and previous folder function does not function on a disc that was recorded without folders or playlists.

When displaying the name of the folder, the radio displays ROOT.

When the disc contains only playlists and compressed audio files, but no folders, all files are located under the root folder. The folder down and the folder up buttons search playlists first and then go to the root folder. When the radio displays the name of the folder, the radio displays ROOT.

Order of Play

Compressed audio files are accessed in the following order:
• Playlists (Px).
• Files stored in the root directory.
• Files stored in folders in the root directory.

Tracks are played in the following order:
• Play begins from the first track in the first playlist and continues sequentially through all tracks in each playlist. When the last track of the last playlist has played, play continues from the first track of the first playlist.
• Play begins from the first track in the first folder and continues sequentially through all tracks in each folder. When the last track of the last folder has played, play continues from the first track of the first folder.

When play enters a new folder, the display does not automatically show the new folder name unless the folder mode has been chosen as the default display. The new track name displays.

File System and Naming

The song name that displays is the song name that is contained in the ID3 tag. If the song name is not present in the ID3 tag, then the radio displays the file name without the extension (such as .mp3) as the track name.

Track names longer than 32 characters or 4 pages are shortened. Parts of words on the last page of text and the extension of the file name do not display.

Preprogrammed Playlists

Preprogrammed playlists that were created using WinAmp™, MusicMatch™, or Real Jukebox™ software can be accessed; however, they cannot be edited using the radio. These playlists are treated as special folders containing compressed audio song files.

Playlists that have an .m3u or .pls file extension and are stored on a USB device may be supported by the radio with a USB port.
