Nissan X-Trail T32 radio pinout: connectors, wire colors and connection diagrams

Nissan X-Trail T32 (2014–2020) was equipped with standard radios with a unique connection system, which often raises questions among owners when replacing them with aftermarket multimedia systems. Unlike earlier models, it uses a combination connector Nissan Consult with non-standard pinout, and the colors of the wires may differ even depending on the vehicle configuration.

If you are planning to install a new radio with support Apple CarPlay or Android Auto, it is important to correctly identify the power, speaker and antenna wires. Connection errors can lead to a short circuit, amplifier failure, or even blocking the standard system Bose (if installed). This article contains current pinout diagrams, step-by-step instructions and nuances that are not written about in standard manuals.

Standard radio connectors Nissan X-Trail T32: where to look and how to distinguish

B X-Trail T32 There are two main connectors used to connect the radio:

• 🔌 Main power and speaker connector - 20-pin block (often mistakenly called "ISO", although this is not a standard ISO 10487). Located at the back of the radio, it has a trapezoidal shape with a lock.
• 📡 Connector for antenna and additional signals — separate 6-pin connector (can be combined with the rear view camera connector in top trim levels).

In vehicles with the system Bose a third connector has been added - for connecting an external amplifier. It is easily identified by the thick orange and black cable that runs to the amplifier in the trunk. Connecting a non-original radio without an adapter to a Bose amplifier will result in no sound at mid and high frequencies. — the standard system uses a digital signal, not an analog one.

To get to the connectors you need to:

1. Remove the decorative frame of the radio (pry it off with plastic paddles on the passenger side).
2. Unscrew two screws Torx T20 on the sides of the head unit.
3. Carefully pull the radio towards you, having first disconnected the retaining clips.

Pinout of the main connector: wire colors and purpose

The main 20-pin connector is responsible for power supply, control and speaker connections. Below is the current diagram for most configurations X-Trail T32 (2014–2020). Please note: Colors may vary slightly depending on production year and market (e.g. European and Japanese versions).

Contact number	Wire color	Purpose	Notes
1	Yellow	Battery +12V	Constant battery power
2	Red	ACC +12V	Power when ignition is turned on
3	Black	GND (Ground)	General minus
4	Green/black	Parking Brake	Parking brake signal (for video while driving)
10–13	Grey, green, purple, white	Front speakers (FL+/FL-/FR+/FR-)	Polarity is important for correct sound

Rear speakers use pins 14–17 (orange, light green, pink, brown). On systems with Bose Speaker wires can be shielded with foil - they should not be confused with antenna cables!

⚠️ Attention: Available with NissanConnect (navigation) contact 6 (blue wire) is responsible for the signal Speed Pulse — speed impulses for correct navigation operation. When installing a non-original radio, this wire can be left unconnected, but then the speed binding to the cards will disappear.

Connecting an antenna and rear view camera: nuances

Antenna connector in X-Trail T32 - standard FAKRA (type SMB), but with an unusual pinout:

• 📶 Central contact — antenna signal.
• 🛡️ Screen (braid) — mass.
• 🔴 Red wire (if any) - power supply to the active antenna (+12V).

Cars with a rear view camera use a separate connector RCA (yellow "tulip") for video signal. Important: the camera is activated by the reverse gear signal (purple wire in the main connector, contact 5). If, after installing a new radio, the camera does not turn on automatically, check:

1. Connecting the purple wire to the contact Reverse on a new radio.
2. Menu settings (in some models you need to manually activate the option Rear Camera).

What to do if the camera shows a mirror image?

In the radio settings, find the option Camera Flip or Mirror Image and turn it off. If there is no option, check the polarity of the video connector (swap the central contact and the screen).

Compatibility with aftermarket radios: what adapters are needed

To connect radios Pioneer, Sony or Alpine you will need:

1. Power adapter - converts the connector Nissan Consult to standard ISO (For example, Metra 70-7552).
2. Antenna adapter — FAKRA on ISO (if the new radio does not support FAKRA).
3. Camera interface - if the standard camera is analog (RCA), and the new radio requires a digital signal.

For systems with Bose additionally needed amplifier emulator (For example, Nissan Bose Amp Bypass), since the standard amplifier expects a digital signal from the original radio. Without an emulator, the sound will be distorted or absent altogether.

⚠️ Attention: In radios with Android Auto The microphone of the standard public address system may not work. To solve the problem, you will need a separate microphone (for example, Parrot MKi9200) or radio firmware with support Nissan MIC.

Common connection mistakes and how to avoid them

Mistake #1: Wires mixed up Battery +12V And ACC +12V. Symptoms: the radio does not save settings (time, radio stations) or does not turn off when the key is removed. Solution: yellow wire - constant power, red - only when the ignition is on.

Mistake #2: Ignoring the wire Parking Brake. In some radios (for example, Pioneer AVH-Z5200BT) Without connecting this wire, watching videos on the go is blocked. Solution: connect to the parking brake sensor or “deceive” the radio by shorting the wire to ground (but this violates traffic rules!).

Mistake #3: Speaker polarity is incorrect. Signs: weak bass, “dirty” sound. Solution: check polarity with a tester or swap positions + And − on one of the front axle speakers.

Step-by-step instructions for replacing the radio

To replace the radio in X-Trail T32 you will need:

• 🔧 Screwdriver Torx T20.
• 🔌 Plastic spatulas for removing the panel.
• 📶 Adapters (see section above).
• 🔋 Multimeter for checking voltage.

Step 1. Dismantling the old radio

Disconnect the battery (remove the negative terminal). Remove the radio frame, unscrew the screws and carefully pull out the device, disconnecting all connectors. Take a photo of the wire location - this will help with reassembly.

Step 2. Connecting adapters

Connect the power and speaker connectors via an adapter Metra 70-7552. Connect the antenna and camera (use adapters if necessary). Check the voltage with a multimeter Battery +12V (should be ~12.6V) and ACC +12V (appears when you turn the key).

Step 3. Installing a new radio

Insert the radio into the seat, secure it with screws and connect the connectors. Turn on the ignition and check:

• 🔊 The operation of the speakers (is there any wheezing or lack of sound).
• 📱 Connecting a smartphone via Bluetooth/USB.
• 🎥 Rear view camera operation.

FAQ: answers to frequently asked questions

Is it possible to connect a radio without an adapter?

Technically yes, but it would require direct soldering of wires, which is not recommended: there is a high risk of short circuit or damage to the standard wiring. Adapter Metra 70-7552 is inexpensive (~1,500 ₽) and guarantees a secure connection.

Why doesn't the microphone work after replacing the radio?

Standard microphone in X-Trail T32 connected to the original radio using a digital protocol. Solutions:

1. Buy an external microphone (for example, Parrot).
2. Use a radio with support Nissan MIC (For example, Pioneer SPH-DA120).

How to reset the error No Sound System after connection?

This error appears if the radio does not see the amplifier Bose. Solutions:

• Install an amplifier emulator (for example, Nissan Bose Amp Bypass).
• Disable option Bose System in the radio settings (if available).

In some cases, resetting the radio settings to factory settings helps (Reset).

Which radio to choose for X-Trail T32 with a 360° camera?

To support all-round visibility, models with 4-channel RCA input for cameras, for example:

• Alpine Halo9 iLX-F411 (requires camera adapter).
• Pioneer AVH-Z9200DAB (compatible with Nissan 360° through Maestro RR).

Please note: standard cameras Nissan transmit an analog signal, so a converter may be required AHD-to-RCA.
