Nissan Sentra B18 (2020-2025) Owner's Manual: Radio

Place the ignition switch in the ACC or ON position and press the PUSH button to switch the radio on. When listening to the radio in your Nissan Sentra with the engine turned off, always keep the ignition switch in the ACC position to avoid unnecessary battery discharge.

Radio reception quality in the Nissan Sentra is influenced by several factors, including station signal strength, distance from the broadcast transmitter, surrounding buildings, bridges, mountains, and other environmental conditions. Temporary fluctuations in reception quality are normal and usually result from these external influences.

Using a cellular phone inside or near the vehicle may also affect radio reception quality.

Radio reception

Your Nissan Sentra audio system is equipped with advanced electronic circuits designed to enhance radio reception. These systems help extend the reception range and improve overall sound clarity under normal driving conditions.

Despite the use of high-quality components, certain natural characteristics of both FM and AM radio signals can affect reception in a moving vehicle. These behaviors are normal within a given reception area and do not indicate a malfunction of the Nissan Sentra radio system.

Reception conditions change continuously as the vehicle moves.

Obstructions such as buildings, terrain variations, signal distance, and interference from other vehicles may reduce ideal reception. The factors described below commonly influence radio performance.

Some cellular phones and electronic devices may cause interference or a buzzing sound from the audio system speakers.

Placing such devices in a different location inside the Nissan Sentra may reduce or eliminate this noise.

FM radio reception

Range: FM reception is typically limited to approximately 25–30 miles (40–48 km). Monaural (single-channel) FM signals generally have a slightly longer range than stereo FM. External conditions may interfere with FM reception even when the broadcast station is within 25 miles (40 km). FM signal strength is directly related to the distance between the transmitter and the receiver. FM signals travel in a line-of-sight path and share characteristics similar to light, including reflection from surrounding objects.

Fade and drift: As your Nissan Sentra moves farther from the transmitting station, the signal may gradually fade or drift.

Static and flutter: Interference from buildings, large hills, or antenna positioning—often combined with increased distance from the transmitter—may cause static or fluttering sounds.

Reducing the treble setting may help minimize this effect.

Multipath reception: Due to the reflective nature of FM signals, both direct and reflected signals may reach the receiver simultaneously. This can cause signal cancellation, resulting in brief sound loss or flutter.

AM radio reception

AM signals operate at lower frequencies, allowing them to bend around objects and travel along the ground. They may also reflect off the ionosphere and return to the earth. Because of these characteristics, AM signals are more susceptible to interference during transmission.

Fading: This may occur when driving through freeway underpasses or areas with numerous tall buildings. Fading can also happen briefly during ionospheric disturbances, even in open areas.

Static: Static noise may be caused by thunderstorms, electrical power lines, illuminated signs, or traffic signals.

Satellite radio antenna

When using satellite radio for the first time in your Nissan Sentra, or after the vehicle battery has been replaced, the system may not operate immediately. This is normal. Allow more than 10 minutes with the satellite radio turned ON while the vehicle is parked outdoors and away from large buildings or metal structures so the system can receive the required data.

Satellite radio operation requires an active SiriusXM Satellite Radio subscription. Satellite radio service is not available in Alaska, Hawaii, or Guam.

Satellite radio performance may be reduced if cargo on the roof obstructs the antenna signal.

Whenever possible, avoid placing cargo near the satellite radio antenna.

A buildup of ice on the satellite radio antenna can also affect reception quality.

Remove any ice accumulation to restore optimal satellite radio performance in the Nissan Sentra.
