Nissan Altima Owners Manual: Audio operation precautions
Compact disc (CD) player
● Do not force a compact disc into the CD insert slot. This could damage the CD and/or CD player.
● Trying to load a CD with the CD door closed could damage the CD and/or CD player.
● Only one CD can be loaded into the CD player at a time.
● Only use high quality 4.7 in (12 cm) round discs that have the “COMPACT disc DIGITAL AUDIO” logo on the disc or packaging.
● During cold weather or rainy days, the player may malfunction due to the humidity.
If this occurs, remove the CD and dehumidify or ventilate the player completely.
● The player may skip while driving on rough roads.
● The CD player sometimes cannot function when the compartment temperature is extremely high or low.
Decrease/increase the temperature before use.
● Do not expose the CD to direct sunlight.
● CDs that are in poor condition or are dirty, scratched or covered with fingerprints may not work properly.
● The following CDs may not work properly: ● Copy control compact discs (CCCD) ● Recordable compact discs (CD-R) ● Rewritable compact discs (CD-RW)
● Do not use the following CDs as they may cause the CD player to malfunction: ● 3.1 in (8 cm) discs with an adapter ● CDs that are not round ● CDs with a paper label ● CDs that are warped, scratched, or have abnormal edges
● This audio system can only play prerecorded CDs. It has no capability to record or burn CDs.
● If the CD cannot be played, one of the following messages will be displayed.
● Confirm that the CD is inserted correctly (the label side is facing up, etc.).
● Confirm that the CD is not bent or warped and it is free of scratches.
This is an error due to excessive temperature inside the player. Remove the CD by pressing the EJECT button. After a short time, reinsert the CD. The CD can be played when the temperature of the player returns to normal.
The file is unplayable in this audio system (only MP3 orWMA(if so equipped) CD).
Compact disc with MP3 or WMA (if so equipped)
● MP3 — MP3 is short for Moving Pictures Experts Group Audio Layer 3. MP3 is the most well-known compressed digital audio file format. This format allows for near “CD quality” sound, but at a fraction of the size of normal audio files. MP3 conversion of an audio track from CD-ROM can reduce the file size by approximately a 10:1 ratio with virtually no perceptible loss in quality. MP3 compression removes the redundant and irrelevant parts of a sound signal that the human ear doesn’t hear.
● WMA—Windows Media Audio (WMA)* is a compressed audio format created by Microsoft as an alternative to MP3. The WMA codec offers greater file compression than the MP3 codec, enabling storage of more digital audio tracks in the same amount of space when compared to MP3s at the same level of quality.
● Bit rate — Bit rate denotes the number of bits per second used by a digital music file.
The size and quality of a compressed digital audio file is determined by the bit rate used when encoding the file.
● Sampling frequency — Sampling frequency is the rate at which the samples of a signal are converted from analog to digital (A/D conversion) per second.
● Multisession — Multisession is one of the methods for writing data to media. Writing data once to the media is called a single session, and writing more than once is called a multisession.
● ID3/WMA Tag — The ID3/WMA tag is the part of the encoded MP3 or WMA file that contains information about the digital music file such as song title, artist, encoding bit rate, track time duration, etc. ID3 tag information is displayed on the Artist/song title line on the display.

Playback order chart
Music playback order of a CD with MP3 or WMA files is as illustrated.
● The names of folders not containing MP3 or WMA files are not shown in the display.
● If there is a file in the top level of the disc, “Root Folder” is displayed.
● The playback order is the order in which the files were written by the writing software.
Therefore, the files might not play in the desired order.
*1 Files created with a combination of 48 kHz sampling frequency and 64 kbps bit rate cannot be played.
*2 Available codes depend on what kind of media, versions and information are going to be displayed.
USB (Universal Serial Bus) memory (if so equipped)
Do not connect/disconnect or operate the USB device while driving. Doing so can be a distraction. If distracted you could lose control of your vehicle and cause an accident or serious injury.
● Do not force the USB device into the USB port. Inserting the USB device tilted or up-side-down into the port may damage the port. Make sure that the USB device is connected correctly into the USB port.
● Do not grab the USB port cover (if so equipped) when pulling the USB device out of the port. This could damage the port and the cover.
● Do not leave the USB cable in a place where it can be pulled unintentionally.
Pulling the cable may damage the port.
The vehicle is not equipped with a USB device.
USB devices should be purchased separately as necessary.
This system cannot be used to format USB devices.
To format a USB device, use a personal computer.
In some states/area, the USB device for the front seats plays only sound without images for regulatory reasons, even when the vehicle is parked.
This system supports various USB memory devices, USB hard drives and iPod® players. Some USB devices may not be supported by this system.
● Partitioned USB devices may not play correctly.
● Some characters used in other languages (Chinese, Japanese, etc.) may not appear properly in the display. Using English language characters with a USB device is recommended.
General notes for USB use:

● An iPod® nano (1st Generation) may remain in fast forward or rewind mode if it is connected during a seek operation. In this case, please manually reset the iPod®.
● An iPod® nano (2nd Generation) will continue to fast-forward or rewind if it is disconnected during a seek operation.
● An incorrect song title may appear when the Play Mode is changed while using an iPod® nano (2nd Generation).
● Audiobooks may not play in the same order as they appear on an iPod®.
● Large video files cause slow responses in an iPod®. The vehicle center display may momentarily black out, but will soon recover.
● If an iPod® automatically selects large video files while in the shuffle mode, the vehicle center display may momentarily black out, but will soon recover.
Bluetooth® streaming audio
● Some Bluetooth® audio devices may not be recognized by the in-vehicle audio system.
● It is necessary to set up the wireless connection between a compatible Bluetooth® audio device and the in-vehicle Bluetooth® module before using the Bluetooth® audio.
● Operating procedure of the Bluetooth® audio will vary depending on the devices. Make sure how to operate your audio device before using it with this system.
