Which radio should I choose for the X-Trail T31: 1DIN or 2DIN?

Choosing the size of the radio depends on your needs and budget. 1DIN (height 50 mm) - a compact option that does not require modification of the panel, but is limited in functionality. 2DIN (height 100 mm) allows you to install a multimedia system with a touch screen, but will require replacing the frame or modifying the seat.

Benefits 2DIN-radio:

  • 📱 Support Android Auto And Apple CarPlay (For example, Pioneer SPH-DA160DAB or Sony XAV-AX5000).
  • 🎥 Possibility of connecting a rear view camera (relevant for X-Trail T31 without standard camera).
  • 🔊 Better sound processing (built-in equalizers, support FLAC/WAV).
  • 📡 Built-in GPS navigator (in some models).

If you're not ready to change the panel, consider 1DIN-options with a retractable screen (for example, Alpine iLX-W650) or models with a separate monitor on the dashboard. Suitable for lovers of retro style Clarion FX502E — a modern radio in a classic case, but with Bluetooth and USB.

📊 What kind of radio are you planning to install?
  • 1DIN (compact)
  • 2DIN (with screen)
  • With pull-out display
  • I haven't decided yet
⚠️ Attention: When installing 2DIN- radios in X-Trail T31 Often it is necessary to replace the climate control with a model with separate buttons (for example, from Nissan Qashqai J10), since the standard panel covers part of the screen.

Connection diagrams for the radio in the Nissan X-Trail T31

Connecting a new radio to X-Trail T31 requires understanding the pinout of the standard connector ISO. This generation uses standard ISO-10487, but with some features:

  • 🔌 Yellow wire (B+) - constant power supply (12V).
  • 🔌 Red wire (ACC) — power supply when the ignition is on.
  • 🔌 Black wire (GND) - mass.
  • 🔌 Blue/White Wire (REM) — antenna/amplifier control.

For radios with Android Auto or Apple CarPlay will need to connect CAN bus (if you need to save the steering wheel buttons). B X-Trail T31 CAN-signals are in orange (CAN-H) and orange-black (CAN-L) wires. To process them you need an adapter, for example, PAC RP4-NIS01.

Wire color Purpose Notes
Yellow B+ (constant +12V) Connect directly to the battery or through a fuse.
Red ACC (+12V at ignition) Can be taken from the ignition switch or used CAN-adapter
Black GND (mass) It is better to attach it to a metal part of the body.
Blue/white REM (antenna control) Important for automatic switching on of the amplifier Bose.

If your car has a system Bose, you will need an additional adapter to keep the amplifier running. Popular models:

  • 🔊 Metra 70-7552 - adapter for saving Bose and steering wheel buttons.
  • 🔊 PAC RP4-NIS01 - supports CAN-bus and integration with the on-board system.

Setting up sound and solving common problems

After installing the new radio in X-Trail T31 There are often problems with sound. Main reasons:

  • 🔇 Quiet sound - wire not connected REM (blue/white) or there is no adapter for Bose.
  • 🎛️ Distortion at high frequencies — the equalizer is incorrectly set or the speaker impedance is incompatible.
  • 🔊 No sound from behind — the rear channels are not connected or there is a problem with the amplifier Bose.

To optimize the sound:

  1. Disable all sound processing in the radio settings (for example, Loudness, Bass Boost).
  2. Set the equalizer to a flat frequency response (all sliders to 0).
  3. Check the balance and fader (should be in the center).
  4. If used Bose, reduce the level of low frequencies - standard speakers are not designed for deep bass.
⚠️ Attention: If after replacing the radio the parking sensors stop working, check the connection to CAN-tire. B X-Trail T31 parking sensor signals can be sent through the audio system (in configurations with a rear view camera).
How to reset the radio settings to factory settings?

For most radios (for example, Pioneer or Sony) you need:

1. Turn off the radio.

2. Press the button SRC (or Menu).

3. Turn on the ignition by holding the button for 5–10 seconds.

4. Select from the menu Reset or Factory Default.

For Android-the radio may need to be reset via Recovery (similar to a smartphone).

Compatible with steering wheel buttons and CAN bus

One of the main problems when replacing a radio in Nissan X-Trail T31 is the loss of functionality of the steering wheel buttons. This is due to the fact that the signals from the buttons are transmitted via CAN-bus, and most after-market radios do not know how to handle them.

Solutions:

  • 🔄 CAN adapter (For example, PAC RP4-NIS01 or Metra AX-NIS32) - converts signals CAN to standard commands for the radio.
  • 🎛️ Flashing the radio (relevant for Android-devices, for example, Joying or Atoto).
  • 🔧 Connecting buttons directly — requires soldering work and knowledge of the circuit (not recommended for beginners).

To connect the adapter:

  1. Find CAN-H (orange) and CAN-L (orange-black) wires in standard connector.
  2. Connect them to the corresponding adapter pins.
  3. Connect the adapter output to the radio connector (usually KEY1 And KEY2).
  4. Set up the adapter according to the instructions (you may need to select your car model from the menu).
💡

Without a CAN adapter, the steering buttons will not work. Even if the radio supports “universal” connection of buttons, this will not work in the X-Trail T31 due to the specific CAN protocol.
