Nissan Sentra B18 (2020-2025) Owner's Manual: Audio operation precautions

MP3 or WMA terms

• MP3 – MP3 stands for Moving Pictures Experts Group Audio Layer 3. It is one of the most widely used compressed digital audio file formats. In the Nissan Sentra audio system, MP3 files allow playback of near “CD-quality” sound while using significantly less storage space than uncompressed audio files. When an audio track is converted from a CD-ROM to MP3 format, the file size can typically be reduced by about a 10:1 ratio with little or no noticeable loss in sound quality. This is achieved by removing redundant and inaudible parts of the sound signal that the human ear cannot perceive.
• WMA – Windows Media Audio (WMA)* is a compressed audio format developed by Microsoft as an alternative to MP3. The WMA codec provides higher compression efficiency than MP3, allowing more music tracks to be stored in the same amount of memory while maintaining comparable sound quality when used with the Nissan Sentra audio system.
• Bit rate – Bit rate refers to the number of bits processed per second in a digital audio file. The overall size and sound quality of a compressed music file are directly related to the bit rate selected during encoding. Higher bit rates generally result in better sound quality but larger file sizes when played in the Nissan Sentra.
• Sampling frequency – Sampling frequency is the rate at which an analog audio signal is converted into a digital signal during analog-to-digital (A/D) conversion. A higher sampling frequency allows for more accurate sound reproduction.
• Multisession – Multisession describes a method of writing data to storage media. Writing data once is referred to as a single session, while writing additional data at different times is called a multisession. Some multisession discs may not be fully compatible with the Nissan Sentra audio system.
• ID3/WMA Tag – The ID3 or WMA tag is the portion of an encoded MP3 or WMA file that contains descriptive information such as the song title, artist name, album, bit rate, and track duration. In the Nissan Sentra, ID3 tag information is displayed on the artist and song title line of the audio display.

USB (Universal Serial Bus) Connection Port

WARNING

• Do not connect, disconnect, or operate a USB device while driving. Doing so may distract the driver. If you become distracted, you could lose control of the Nissan Sentra and cause an accident resulting in serious injury or death.

CAUTION

• Do not force a USB device into the USB port. Inserting the device at an angle or upside down may damage the port. Always ensure that the USB device is correctly aligned before connection.
• Do not pull on the USB port cover (if so equipped) when removing a USB device. This could damage both the cover and the USB port.
• Do not leave the USB cable where it may be pulled unintentionally. Pulling on the cable may damage the USB port.

The Nissan Sentra is not supplied with a USB storage device.

USB devices must be purchased separately as needed.

This audio system cannot be used to format USB devices. To format a USB device, use a personal computer before connecting it to the Nissan Sentra.

In some regions, the USB connection for the front seats may support audio playback only, without image display, due to local regulations, even when the vehicle is parked.

The Nissan Sentra audio system supports a wide range of USB memory devices, USB hard drives, and iPod players. However, some USB devices may not be compatible with this system.

• Partitioned USB devices may not operate correctly.
• Characters from certain languages (such as Chinese or Japanese) may not display properly. For best results, use English characters for file and folder names on USB devices used in the Nissan Sentra.

General notes for USB use:

• Refer to the USB device manufacturer’s instructions for proper use, handling, and care of the device.

Notes for iPod use:

iPod is a trademark of Apple Inc., registered in the United States and other countries.

• If the iPod is not connected properly, a checkmark icon may appear and disappear repeatedly. Always ensure the iPod is securely connected to the Nissan Sentra audio system.
• Audiobooks may not play in the same sequence as shown on the iPod.
• Large video files stored on an iPod may cause slow system response. In some cases, the center display may temporarily go black but will recover automatically.
• If large video files are selected during shuffle playback, the center display may momentarily turn black and then return to normal operation.

iPod* player

• Some characters used in non-Latin languages (such as Chinese or Japanese) may not be displayed correctly on the vehicle center screen. For optimal compatibility and readability when using the iPod player in the Nissan Sentra, it is recommended to use English or Spanish characters for song titles, albums, and artist names.
• Large video podcast files may cause slower response times from the iPod. In such cases, the Nissan Sentra center display may temporarily turn black; however, normal operation will resume shortly without indicating a malfunction.
• If the iPod automatically selects large video podcast files while operating in shuffle mode, the vehicle center display may momentarily black out and then recover. This behavior is considered normal system operation.
• An improperly connected iPod cable may cause a checkmark icon to appear and disappear repeatedly (flickering). Always ensure the iPod cable is securely and correctly connected before use in the Nissan Sentra.
• Audiobooks may not play back in the same sequence as they are listed on the iPod. Playback order is determined by the iPod’s internal indexing.
• To prevent cable damage and possible loss of function, avoid the following conditions when using the iPod connection cable in the Nissan Sentra:
  • Bending the cable excessively (maximum bend radius of approximately 1.6 in (40 mm)).
  • Twisting the cable beyond 180 degrees.
  • Pulling, stretching, or dropping the cable.
  • Forcing the iPod cable connector into the device port.
  • Closing the center console lid on the cable or connectors.
  • Storing sharp-edged objects near the cable.
  • Spilling liquids on the cable or connectors.
• Do not connect the cable to the iPod if the cable or connectors are wet, as this may cause permanent damage to the device.
• If the cable or connectors have been exposed to water, allow them to dry completely before reconnecting to the iPod. A drying period of at least 24 hours is recommended.
• If the connector is exposed to liquids other than water, evaporative residue may create a short circuit between connector pins. In this case, replace the cable to prevent damage and loss of functionality.
• If the cable shows visible damage (such as cut insulation, cracked connectors, or contamination from liquids, dust, or debris), discontinue use immediately. It is recommended that you visit a NISSAN dealer to replace the cable with a genuine replacement.
• When the iPod cable is not used for extended periods, store it in a clean, dry, dust-free environment at room temperature and away from direct sunlight.
• Use the iPod cable only for its intended purpose within the Nissan Sentra audio system.

Bluetooth streaming audio

• Some Bluetooth audio devices may not be recognized or may have limited functionality when paired with the Nissan Sentra audio system.
• Before using Bluetooth streaming audio, a wireless connection must be properly established between a compatible Bluetooth audio device and the in-vehicle Bluetooth module.
• Bluetooth audio operating procedures vary depending on the device used. Become familiar with your device’s controls before using it with the Nissan Sentra audio system.
• Bluetooth audio playback may be interrupted under the following conditions:
  • When receiving a call through the Bluetooth Hands-Free Phone System.
  • When the system is checking or re-establishing the hands-free phone connection.
• Do not place the Bluetooth audio device in an area surrounded by metal or far from the in-vehicle Bluetooth module, as this may degrade sound quality or disrupt the wireless connection.
• When a device is connected via Bluetooth, its battery may discharge faster than usual due to continuous wireless communication.
• The Nissan Sentra audio system supports Bluetooth Audio Distribution Profile (A2DP) and Audio/Video Remote Control Profile (AVRCP) for compatible devices.
