Head unit Nissan Qashqai J10 first generation (2007–2013) is a unit that often requires replacement or modernization. Owners are faced with the need to connect a new head unit, restore the functionality of the standard system, or integrate additional equipment (cameras, amplifiers). Without precise pinout of connectors, the risk of connection errors increases: you can burn fuses, damage the speakers or even the multimedia control unit.

In this article you will find detailed pinout diagram head unit Qashqai J10 taking into account the features of different configurations (with Bose and without), as well as practical advice on working with connectors. We will analyze not only standard connectors ISO And Nissan-specific, but also the nuances of connecting to CAN bus, control of steering wheel buttons and integration with on-board electronics. If you plan to install Android Auto or Apple CarPlay, there is critical compatibility information here.

Head unit connectors: types and location

B Nissan Qashqai J10 The radio is connected via two main connectors:

  • 🔌 Main power/audio connector (20-pin, Nissan-specific) - responsible for power, speakers and antenna. Available with Bose has additional contacts for the amplifier.
  • 📡 CAN bus connector (6-pin or 8-pin) - provides communication with the on-board network (displaying information on the display, operation of steering wheel buttons).
  • 🔊 Additional connector (optional) - in versions with Bose or navigation may have a third connector for an amplifier or GPS antenna.

Important: in Qashqai J10 no standard ISO connector — the manufacturer uses proprietary connectors. To connect universal radios you will need adapter (For example, Connects2 CTNI001 or Xcarlink NI10). Without an adapter, you will have to cut the standard wiring, which can lead to loss of warranty (if it is still valid) and difficulties during reinstallation.

The connectors are located behind the radio and are secured with plastic latches. To disconnect them, you must:

  1. Press out the fasteners on the sides of the connector (use a flat-head screwdriver or a plastic spatula).
  2. Pull the connector perpendicular the plane of the radio - not sideways, so as not to damage the contacts.
  3. When connecting a new device, make sure that the latches click into place.

Pinout of the main connector (20-pin): power and audio

The main connector contains contacts for power, speakers, antenna, and (in some versions) amplifier control. Below is the diagram for basic configuration without Bose:

Contact number Wire color Purpose Notes
1 Yellow BATTERY +12V Constant power supply from the battery (via fuse F37 (10A) in the cabin block).
2 Red IGNITION +12V Power supply when the ignition is on (via fuse F10 (10A)).
3 Black GND (Ground) General minus. Must be securely attached to the body.
4 Orange ILLUMINATION Button illumination (controlled by the dashboard lighting rheostat).
5–8 Green, purple, gray, white Front left/right and rear left/right speakers (+) Polarity is important! Failure to comply will result in antiphase.
9–12 Black-green, black-purple, etc. Speakers (-) Negative wires are always black with a colored stripe.
13 Blue ANTENNA CONTROL Active antenna control (if installed).

Critical note: in versions with system Bose Pins 5-12 do not go directly to the speakers, but are connected to the amplifier (located under the front passenger seat). Connecting a universal radio without an amplifier bypass will result in no sound!

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

  • 🔋 Between yellow (pin 1) And black (pin 3) there must be 12.6V (with the ignition off).
  • 🔑 Between red (pin 2) And black — 12.6V only when the ignition is on.

If there is no voltage, check the fuses F37 And F10 in the cabin block (left side of the steering column).

CAN bus and steering buttons: pinout and nuances

CAN bus connector in Qashqai J10 is responsible for:

  • 📱 Display information on the on-board computer display (track, radio station).
  • 🎵 Controlling the radio from the steering wheel buttons (MODE, VOL+/-, SEEK).
  • ⚠️ Error diagnosis (for example, code U1000 — loss of connection with CAN).

Pinout diagram for 6-pin connector:

Contact Wire color Purpose
1 Green-white CAN HIGH
2 Yellow-green CAN LOW
3 Red +12V (power supply to CAN module)
6 Black GND

Attention! Connecting a universal radio without a CAN adapter will lead to:

⚠️ Loss of functionality of steering wheel buttons and error U1000 in the on-board computer. For integration you will need a module like Pac RP4-NIS01 or Connects2 CTNI002, which emulates the signals of the standard radio.

If, after connecting a new head unit, the icon appears on the dashboard ! next to the clock - this indicates a lack of CAN communication. In this case:

  1. Check the integrity of the wires CAN HIGH And CAN LOW (pins 1 and 2).
  2. Make sure the adapter supports the protocol Nissan Consult III.
  3. Reset errors via diagnostic scanner (eg Launch X431).
How to check the CAN bus without a scanner?

Connect the multimeter in mode DC 20V between CAN HIGH (pin 1) and CAN LOW (pin 2). When the ignition is running, the voltage should be in the range 2.5–3.5V. If it shows 0V or 12V - open circuit or short circuit. You can also temporarily turn off the radio and check if the error disappears U1000 (if yes, the problem is in the head unit or adapter).

Features of versions with the system Bose

Available with audio system Bose The connection diagram becomes more complicated due to an external amplifier. It is located under the front passenger seat and has a separate fuse box (F40 (30A) And F41 (10A)).

Key pinout differences:

  • 🔊 Pins 5–12 of the main connector don't go to the speakers, and are connected to the amplifier via RCA connectors (if they are not there, the signal is transmitted via a digital bus).
  • 🔋 The amplifier requires separate power (+12V on the orange-black wire in the additional connector).
  • 📉 When replacing the radio with a universal one amplifier bypass required (For example, LC7i from AudioControl), otherwise the sound will be distorted or absent.

Amplifier connection diagram Bose:



Усилитель Bose (разъём 16-pin):


1  — +12V (оранжево-чёрный, предохранитель F40)


2  — GND (чёрный)


3–10 — Входы от магнитолы (RCA или цифровой сигнал)


11–16 — Выходы на динамики (мощность 180W на канал)

Attention! If after replacing the radio, the amplifier Bose does not turn on:

⚠️ Check for signal REMOTE (usually the blue wire in the main connector). In some cases, a signal emulator is required (for example, Pac TR-7), since the standard radio sends the power-on command via the CAN bus.
💡

If you install a radio without digital output support (for example, a budget Pioneer), use a DAC converter to convert the analog signal into a format that the amplifier can understand Bose.

Compatibility with alternative radios

When choosing a new radio for Qashqai J10 consider the following criteria:

  • 🔌 Connection type: Without an adapter, only devices that support Nissan-specific connectors (for example, Clarion NX409 or Kenwood DDX4060BT).
  • 📱 CAN integration: An adapter is required to operate the steering wheel buttons and display tracks on the display (see section above).
  • 🔊 Output power: if you have Bose, the radio must have linear outputs RCA (minimum 4 channels).
  • 📡 Antenna: in Qashqai J10 an active antenna is used (controlled by the blue wire, pin 13).

Recommended replacement models:

Model Type CAN adapter Notes
Pioneer SPH-DA160DAB Android Auto / CarPlay Required Pac RP4-NIS01 Supports digital radio, but requires an external antenna.
Sony XAV-AX5000 Android Auto / CarPlay Required Connects2 CTNI002 10.1" display, but deep seating - may interfere with climate control.
Alpine iLX-W650 Wireless CarPlay Built-in support Nissan Compact size, but no DVD drive.

For Chinese multimedia complexes (for example, Joying or Atoto) you will need:

  1. Power adapter (they often don't support IGNITION +12V on a separate wire).
  2. CAN box with firmware for Qashqai J10 (universal ones will not work!).
  3. Amplifier bypass if you have Bose.
💡

The most reliable option for preserving the functionality of the steering wheel buttons is a radio with built-in support Nissan (For example, Alpine or Kenwood with adapter included). Chinese devices often require modification of the CAN module firmware.

Common mistakes and how to avoid them

Even if the diagrams are followed exactly, owners Qashqai J10 face typical problems:

  1. No sound after replacing radio:
    • 🔊 In versions with Bose forgot to connect the amplifier (check the orange-black wire).
    • 🔌 The polarity of the speakers was mixed up (swap + And - on one speaker - if sound appears, the problem is in polarity).
  2. Steering wheel buttons don't work:
    • ⚠️ The CAN adapter is not connected or it is incompatible with the protocol Consult III.
    • 🔧 Check the integrity of the wires CAN HIGH/LOW (pins 1 and 2).
  3. The radio turns off when the engine starts:
    • 🔋 Confused BATTERY +12V (yellow) and IGNITION +12V (red).
    • 🔌 Weak ground contact (black wire, contact 3).

Attention! If after connecting a new radio the radio stops working parking sensors or rear view camera:

⚠️ This is due to the fact that the standard radio transmits a signal to the on-board computer via the CAN bus. Install an adapter that supports Parking Sensor Interface (For example, Pac RP5-NIS01) or connect the camera directly to the new radio via RCA-entrance

Use a scanner to diagnose errors ELM327 with the program Nissan DataScan. Frequent codes:

  • U1000 — loss of communication with CAN (check the adapter).
  • B1328 — audio system error (the amplifier may not be connected Bose).
  • C1130 — a problem with the parking sensors (you need to reconfigure the radio).

Step-by-step instructions for replacing the radio

To replace the standard radio Nissan Qashqai J10 you will need:

  • 🔧 Plastic spatulas for dismantling the panel.
  • 🔌 Power adapter/CAN (if you are installing a universal radio).
  • 📡 Antenna adapter (if the new radio does not support the standard connector).
  • 🔊 Amplifier crawler (for versions with Bose).

Algorithm of actions:

  1. Disconnect the battery (remove the negative terminal).
  2. Remove the decorative frame:
    • Use a spatula to pry up the bottom of the panel under the climate control.
    • Unclip the 4 latches (2 on top, 2 on the sides).
  3. Remove the radio:
    • Remove 4 screws Torx T20 in the corners.
    • Pull the device towards you, disconnect the connectors (first CAN, then main).
  4. Connect the new radio:
    • Connect the wires through the adapter (follow the color scheme from section 2).
    • Connect the CAN module (if required).
    • Install an antenna adapter (eg Nissan to ISO).
  5. Check functionality:
    • Turn on the ignition, check the power.
    • Test the sound (on all speakers), steering wheel buttons, rear view camera.

Attention! When installing a radio with a large screen (7" or more), the panel may need to be modified:

⚠️ B Qashqai J10 The depth of the compartment for the radio is limited. If the new model is not included, you will have to cut the plastic behind the panel (use Dremel with a nozzle for plastic). Alternative - purchase extension frame (For example, Metra 99-7303).
💡

Before final assembly, turn on the radio and check the temperature of the wires after 10–15 minutes of operation. If any wire gets hot, this is a sign of a short circuit or incorrect connection (most often the culprit is GND).

FAQ: answers to frequently asked questions

Is it possible to connect a universal radio without an adapter?

Technically yes, but you'll have to:

  • Cut standard connectors and connect wires directly (risk of errors and loss of warranty).
  • Avoid steering wheel buttons and display information on the on-board computer.
  • Lay the wires for the antenna and rear view camera yourself.

We recommend using an adapter (eg Connects2 CTNI001) — this preserves the possibility of reinstalling the standard radio.

Why doesn't the rear view camera work after replacing the radio?

Probable reasons:

  1. The new radio does not support NTSC/PAL standard camera format (signal adapter required).
  2. The camera control wire is not connected (usually purple, pin 14 in the main connector).
  3. The CAN adapter does not transmit a signal to engage reverse gear (check the adapter settings).

Solution: use RCA video adapter (For example, Boyo VTL370) or connect the camera directly to the radio via A/V IN.

How to reset the error U1000 after replacing the radio?

Error U1000 indicates a loss of communication with the CAN bus. To reset it:

  1. Connect the diagnostic scanner (Launch CReader or ELM327).
  2. Select module BCM (Body Control Module).
  3. Find the error U1000 and clean it.
  4. If the error appears again, check:
    • Wire integrity CAN HIGH/LOW.
    • CAN adapter protocol compatibility Nissan Consult III.
    • Availability of power on the CAN module (pin 3, red wire).
Which fuses are responsible for the radio in Qashqai J10?

List of fuses related to the audio system:

fuse Denomination Location Purpose
