Pinout of the standard Nissan X-Trail T32 radio: connectors, wire colors and connection diagram

Head unit in Nissan X-Trail T32 (2014–2020 model year) is not just an audio system, but a key element of the car’s multimedia complex. It is integrated with on-board electronics, a hands-free system and even climate control in top versions. However, when replacing a third-party radio or diagnosing faults, owners are faced with a problem: official documentation does not contain detailed pinouts of connectors, and universal diagrams often do not match the actual wiring.

In this article we will look at exact pinout of the standard radio for X-Trail T32 taking into account the features of different trim levels (including versions with navigation and rear view camera). You will learn which wires are responsible for power, speakers, antenna and CAN bus, as well as how to avoid common mistakes when connecting. The material is based on an analysis of service manuals, wiring diagrams and the experience of auto electricians working with Nissan.

What connectors are used in the standard radio X-Trail T32

B Nissan X-Trail T32 The standard radio is connected via two main connectors:

• 🔌 Connector A (24-pin) — responsible for power supply, speakers and control. Used in all versions, including basic ones.
• 📡 Connector B (16-pin) — connects an antenna, CAN bus, rear view camera and additional functions (for example, Bose in premium trim levels).

Depending on the year of manufacture and configuration, the number of contacts may vary slightly. For example, in 2017–2020 models with NissanConnect added wires for USB And AUX, which are displayed separately. It is also important to note that in versions with Bose The wiring diagram for the speakers is different - they use amplifiers rather than a direct connection.

To accurately determine the type of connector in your car, pay attention to the markings on the radio body or use VIN decoder to check the contents. For example, if in your X-Trail T32 system installed NissanConnect with navigation, then connector B will have additional contacts for GPS antennas And microphone.

Pinout of connector A (24-pin): power and speakers

Connector A is the most important as it carries power and signals to the speakers. Below is a table with the colors of the wires and their purpose for the standard configuration X-Trail T32 (without Bose).

Contact number	Wire color	Purpose	Notes
1	Yellow	Battery +12V	Constant battery power
2	Red	ACC +12V	Power when ignition is on
3	Black	GND (Ground)	General minus
4	Green/black	Right front speaker (+)	Polarity is important for correct sound
5	Green	Right front speaker (–)	Negative wire

Attention: in versions with the Bose system, the wires to the speakers (pins 4–11) do not go directly, but through the amplifier. Connecting a third-party radio without an adapter will result in no sound.

To check the power supply, use a multimeter in DC 20V:

• 🔋 Between pins 1 (yellow) and 3 (black) there should be 12V constantly.
• 🔑 Between pins 2 (red) and 3 (black) 12V appears only when the ignition is on.

If there is no voltage, check the fuses F37 (10A) And F38 (15A) in the block under the hood.

Ring the yellow wire (Battery +12V)

Ring the red wire (ACC +12V)

Check ground (black wire)

Make sure fuses F37 and F38 are intact

Pinout of connector B (16-pin): CAN bus, antenna and camera

Connector B is responsible for connecting the radio with other vehicle systems. Contacts are most critical here CAN-H And CAN-L — their incorrect connection can lead to errors on the dashboard (for example, No Communication with Audio Unit).

Below is the pinout for version with NissanConnect (with navigation and rear view camera):

Contact number	Wire color	Purpose	Notes
1	Orange	CAN-H	High CAN bus level
2	Orange/black	CAN-L	Low CAN bus level
3	Blue	Antennen +12V	Active antenna power supply
4	Brown	Camera +12V	Rear view camera power supply
5	Green/white	Camera Signal	Video signal from camera

⚠️ Attention: When connecting an aftermarket radio CAN bus cannot be ignored. If you don't connect CAN-H And CAN-L, an error message will appear on the dashboard and the steering wheel buttons will stop working. For integration you will need CAN adapter (For example, Connects2 CTNIS001).

To check the rear view camera signal:

1. Turn on the ignition and move the gearshift lever to position R.
2. Measure the voltage on pin 4 (brown) - there should be 12V.
3. Check the resistance between pin 5 (green/white) and ground - it should be within 50–100 Ohm.

If the resistance approaches infinity, the wire may break or the camera may malfunction.

What happens if you confuse CAN-H and CAN-L?

If the CAN bus is connected incorrectly, the radio will not exchange data with the vehicle's control unit. This will lead to:

- No sound through steering wheel buttons

- "Audio Unit Malfunction" error on the dashboard

- Incorrect operation of climate control (in versions with integration)

- Lost connection with the rear view camera

In some cases, the protection may work and the radio will go into "Safe Mode".

Connection features in versions with the Bose system

B Nissan X-Trail T32 with audio system Bose The speaker connection diagram is fundamentally different. Instead of a direct connection, the signal goes through external amplifier, which is located behind the rear trunk trim. This means that:

• 🔊 The wires to the speakers (connector A, pins 4–11) are actually linear outputs to the amplifier.
• 🚫 Connecting a third-party radio directly to these wires won't make a sound - You will need to bypass the amplifier or use an adapter.
• 🔧 In amplifier Bose has its own switching logic, which is synchronized with the radio via the CAN bus.

To integrate an aftermarket radio into the system Bose there are two options:

1. Use adapter (For example, NavTV Zen-BOSE), which emulates the signals of the standard radio and allows you to connect to an amplifier.
2. Bypass amplifierby connecting the speakers directly to the new radio. To do this, you will need to lay new wires from the radio to each speaker (a labor-intensive process).

⚠️ Attention: When bypassing the amplifier Bose you will lose your signature sound settings (equalizer, bass processing, etc.). In addition, in some configurations the amplifier also controls the subwoofer, which will also stop working.

Common connection mistakes and how to avoid them

Even experienced auto electricians make mistakes when working with the radio. Nissan X-Trail T32. Here are the most common problems and how to solve them:

• ⚡ Short circuit in power supply — occurs when the yellow one is connected incorrectly (Battery +12V) or red (ACC +12V) wires. Symptoms: the fuse trips, the radio does not turn on.

  ⚠️ Attention: Never connect both power cords to the same source (such as ACC). This will lead to battery discharge, since the radio will work even when the ignition is turned off.

• 🔇 No sound from speakers - most often caused by incorrect polarity or open ground. Check the black wire on pin 3 of connector A.

  The sound may also disappear due to:

  • 🔌 Unconnected wire ANT Control (blue, connector B) - some radios block audio output without a signal from the antenna.
  • 🎵 Speaker impedance incompatibilities (in Bose 2 ohms are used, and standard radios are designed for 4 ohms).
• 📵 Rear view camera does not work - check:
• 🔋 Power on the brown wire (pin 4, connector B).
• 📺 Signal on the green-white wire (pin 5, connector B).
• 🔧 Setting up the radio: the mode must be activated in the menu Reverse Camera.

Another common mistake is ignoring radio encoding. In some versions NissanConnect After turning off the power, you must enter a PIN code. If you don't know the code, you can get it:

• 📄 From the service book (usually indicated on a sticker along with the VIN).
• 🔑 Through the dealer Nissan by VIN number (for a fee, ~1000–1500 rubles).
• 🛠️ Using specialized software (for example, Nissan Consult), but this requires diagnostic equipment.
