Introduction: why it is important to know the radio pinout Nissan Note

Replacing or upgrading the audio system in Nissan Note (especially models E11 And E12 2006–2016) often becomes a headache for owners due to non-standard connectors and lack of documentation. Head unit Nissan uses a unique 20-pin connector that is not compatible with most generic ISO adapters. Without accurate pinouts, the risk of damaging the car’s electronics or the new radio increases significantly.

In this article you will find detailed pinout diagram for all versions Note, including models with system Bose and navigation. We will analyze the purpose of each wire, the features of connecting non-standard devices (for example, Pioneer or Sony), and also give practical advice on diagnosing typical problems - from lack of sound to CAN bus errors. The material is based on official service manuals Nissan and the experience of auto electricians specializing in Japanese cars.

Standard pinout of the head unit Nissan Note (20-pin connector)

Head unit Nissan Note connects via two connectors: main 20-pin (A) and additional 8-pin (B) for antenna and steering wheel controls. Below is the pinout table for the basic version without Bose:

Contact number Wire color Purpose Notes
A1 Yellow +12V (constant) Power supply for radio memory
A2 Red +12V (ignition) Activated when turning the key
A3 Black Ground (GND) General minus
A10 Green/black CAN-High Data bus for exchange with the control unit
A11 White/black CAN-Low Synchronization with vehicle CAN bus

Feature Nissan Note - use CAN buses to transmit data about the state of the car (for example, speed, engine speed) to the radio display. If you are installing a non-standard device, you will need CAN adapter (For example, Connects2 CTNI23) to maintain the functionality of displaying on-board information.

⚠️ Attention: Connecting a radio without a CAN adapter will lead to loss of data on mileage, fuel consumption and errors on the dashboard. In some cases this may cause U1000 (CAN communication error).

Pinout for versions with system Bose and navigation

Modifications Nissan Note with audio system Bose or factory navigation (Nissan Connect) have an extended pinout. Additionally, contacts appear for:

  • 🔊 Amplifier Bose (orange/gray wires on pins A15–A18).
  • 📡 GPS antennas (blue wire, pin B4).
  • 📱 Bluetooth module (purple/green, pins B6–B7).
  • 🎵 AUX input (green/white, pin A19).

Important: in systems with Bose You cannot connect speakers directly to a non-standard radio - this will lead to sound distortion or failure of the amplifier. Must be used line output (RCA) or a specialized adapter, e.g. Nissan Bose Interface.

Connecting an aftermarket radio: step-by-step instructions

To install a third-party radio (for example, Pioneer AVH-X5800DAB) you will need:

  1. ISO adapter for Nissan Note (For example, Metra 70-7552).
  2. CAN adapter (if you need to save the on-board computer).
  3. A set of crimp terminals and heat shrink tubing.

Connection diagram:

  1. Connect yellow wire adapter with +12V constant (A1).
  2. Connect red wire to +12V ignition (A2).
  3. Black wire - on mass (A3).
  4. For speakers, use pairs:
    • 🔈 Front left/right: gray/gray-black (A4/A5) and white/white-black (A6/A7).
    • 🔈 Rear left/right: green/green-black (A8/A9) and purple/purple-black (A12/A13).

☑️ Check before turning on a new radio

Done: 0 / 4
⚠️ Attention: If after connecting the radio does not turn on, check for voltage on pins A1 and A2 with a multimeter. A common mistake is confusing +12V constant And +12V ignition, which causes the settings to be reset when the engine is turned off.

Diagnosis of typical problems after connection

Even with correct pinout, failures may occur. Let's look at the most common ones:

Problem Possible reason Solution
The radio does not turn on No +12V on A1 or A2 Check fuse F30 (10A) in the passenger compartment
No sound Unconnected speakers or CAN error Ring wires A4–A9, A12–A13. Reset CAN errors with a scanner
Error U1000 on the panel No communication via CAN bus Install a CAN adapter or check pins A10/A11

If the radio turns on, but does not see USB or Bluetooth, the problem may be an incorrect connection of the additional connector B. For diagnostics:

  1. Disconnect connector B and check the integrity of the wires (especially blue and purple).
  2. Update the radio firmware through the manufacturer's official website.
  3. Reset settings to factory defaults (Menu → System → Reset).
What should I do if the radio freezes when connected to the CAN bus?

This is a typical problem with Chinese adapters. Solution:

1. Disconnect the CAN adapter and check it for compatibility with the protocol Nissan (must support ISO 11898-2).

2. Install a 120 ohm resistor between CAN-High And CAN-Low on the adapter.

3. Update the adapter firmware via PC (for example, for Connects2 use the utility CTUpdater).

Adapters and accessories for easy connection

To avoid manual soldering of wires, we recommend using ready-made solutions:

  • 🔌 Adapter Metra 70-7552 - Ensures ISO compatibility, retains steering control.
  • 📶 Connects2 CTNI23 — CAN adapter for integration with the on-board system.
  • 🔊 Nissan Bose Interface - for connecting an aftermarket radio to an amplifier Bose.
  • 📱 Pac RP4-NIS01 — module for saving the rear view camera and parking sensors.

When choosing an adapter, pay attention to CAN protocol version. For Nissan Note 2013+ support required CAN 2.0B, whereas for models 2006–2012 it is suitable CAN 2.0A.

💡

Before purchasing an adapter, check the VIN of your car - some modifications Note for the European and Japanese markets they have different CAN bus pinouts.

Upgrading the audio system: what can be improved

Head unit Nissan Note often criticized for its weak sound and lack of modern features. Here's what you can do to upgrade:

  • 🎛️ Replacing speakers: Install component speakers (such as Focal PS 165) instead of the standard 13 cm speakers.
  • 📻 Amplifier: Add a 4-channel amplifier (such as Alpine KTA-450) to improve bass.
  • 🔋 Capacitor: Install a 1F capacitor (for example, Stinger SPC1000) to stabilize the power supply.
  • 📱 Android Auto/Apple CarPlay: Select a radio that supports wireless connection (such as Sony XAV-AX5500).

When upgrading, consider current limits: standard wiring Nissan Note designed for a maximum power of 180 W. For amplifiers with power over 500 W, you will need to run a separate power cable (at least 4 AWG) directly from the battery.

💡

The weakest point of the standard audio system Nissan Note — front speakers. Replacing them with component acoustics provides the greatest increase in sound quality at minimal cost.

FAQ: Frequently asked questions about radio pinout Nissan Note

Is it possible to connect a radio without a CAN adapter?

Technically yes, but you will lose the display of on-board information (mileage, fuel consumption, engine temperature). In addition, an error message may appear on the dashboard U1000. For models with Bose A CAN adapter is required - otherwise the amplifier will not turn on.

Which fuse controls the radio?

In the interior fuse box (to the left of the steering wheel) this is the fuse F30 (10A) — it protects the power circuit. Also check F15 (15A) - he is responsible for the amplifier (if there is one) Bose).

Why do the steering wheel buttons not work after replacing the radio?

The steering buttons are connected via a CAN bus. For them to work you need an adapter that supports Steering Wheel Control (For example, Pac SWI-RC). An alternative is to reflash the radio for the original commands Nissan (available on some models Pioneer And Alpine).

How to check the integrity of the CAN bus?

Use the multimeter in resistance mode:

  1. Disconnect the radio connector.
  2. Measure the resistance between CAN-High (A10) And CAN-Low (A11).
  3. Normal value - 60–120 Ohm. If the resistance tends to infinity, there is a break; if it approaches zero, there is a short circuit.

For accurate diagnosis, use a scanner (for example, Launch X431).

Is it possible to install a radio with a 2DIN screen in Nissan Note?

Yes, but the panel will need to be modified. Standard place for a radio in Note designed for 1DIN. Options:

  • Install retractable 2DIN (For example, Alpine INE-W990).
  • Use extension panel (For example, Metra 99-7502).
  • Remake the dashboard (requires skills in working with plastic).

Please note that after installing 2DIN, access to the climate control buttons may be blocked.
