Removing the Nissan Qashqai J11 radio: instructions with nuances and life hacks

Removing the standard radio Nissan Qashqai J11 (restyling 2017 or pre-restyling 2014–2016) is a task that owners face when upgrading an audio system, repairing or diagnosing errors. At first glance, the procedure seems simple, but hidden under the plastic panels are non-obvious fastenings, fragile latches and wires that are easy to damage. This article will help you avoid common mistakes: from choosing a tool to correctly disconnecting connectors without the risk of a short circuit.

We'll sort it out three key stages: preparation (including nuances with the battery), dismantling decorative panels and directly removing the head unit. We will pay special attention models with NissanConnect system — there are some peculiarities here with clamps. If you are planning to install a new radio, at the end of the article you will find tips on the compatibility of connectors and adapters.

Preparation: Tools and Safety Precautions

Before you begin dismantling, make sure you have everything you need. Minimum set of tools for Qashqai J11:

• 🔧 Plastic mounting blades (2–3 pcs.) - for removing panels without scratches.
• 🔩 10 mm socket wrench — for unscrewing the radio mounts (in some configurations).
• 📦 Phillips head screwdriver (PH2) - for decorative frame screws.
• 🔌 Multimeter - to check the voltage on the connectors after disconnecting.
• 📱 Smartphone with flashlight — lighting will help you see the latches.

The most critical moment - work with the battery. B Qashqai J11 The radio is connected directly to the on-board network, and if disconnected incorrectly, the fuse can burn F37 (10A) in the block under the hood. Be sure to remove the negative terminal with the battery 10–15 minutes before starting work - this will allow the capacitors in the audio system to discharge.

⚠️ Attention: If your Qashqai equipped with a system Bose, before removing the radio, turn off the amplifier (located in the trunk behind the right trim). Otherwise, when you turn on the power without a connected radio, the speakers may make a popping sound, damaging the membranes.

Removing the decorative frame and panels: step by step

The main difficulty when dismantling the radio is in Nissan Qashqai J11 - this is multi-layer center console design. The radio frame is secured not only with latches, but also with hidden screws. Let's start with the top panel:

1. Open the glove compartment and pull it all the way out - this will give access to two screws under the frame. They are hidden behind the plugs (carefully pry them off with a spatula).

2. Remove decorative trim around the gearshift lever. It is held on by 4 latches - pull up with force, but without jerking.

3. Unscrew two screws under the cover (they secure the radio frame) and two more - to the right and left of the screen (visible after removing the glove compartment).

4. Gently pull the frame towards you, starting from upper right corner — here the latch is the most fragile. If you feel resistance, check that all screws are unscrewed.

After removing the frame you will see four radio mounting screws (two on top and bottom). Available with NissanConnect Additionally, there may be a metal retaining plate - it must be moved to the left before unscrewing.

Removing the radio: connectors and typical errors

When all fastenings are removed, the radio Qashqai J11 moves forward 5-7 cm - this is enough to get to the connectors. The main thing here is do not pull the wires, and carefully disconnect all connectors. There are three of them:

Connector	Purpose	Color	Features
A	Power (+12V, ACC, ground)	Black	Has a latch - press it before removing
B	Audio inputs/outputs (speakers, antenna)	Gray	Fragile! Do not bend the contacts
C	CAN bus, USB, Aux	White	In configurations with a rear view camera there is an additional wire

The most common mistake is connector damage B (audio). Its contacts are thin, and if removed incorrectly, they bend. If this happens, use tweezers to straighten it. One more nuance: in cars with Bose connector B has an additional wire for the subwoofer - it should not be confused with regular speakers.

⚠️ Attention: If after removing the radio on the connector A voltage remains (check with a multimeter), which means the fuse is not disconnected F37. Working in this condition is dangerous - there is a risk of short circuit when touching metal parts of the body.

What to do if the radio does not come out?

If after unscrewing all the screws the radio does not come out, check:

1. **Metal retaining plate** (in configurations with NissanConnect) - it must be moved to the left.

2. **Hidden latches** on the sides - sometimes they get stuck. Try gently pressing on the side of the radio casing.

3. **Wires** - they may have gotten caught on something in the back. Pull the radio up at an angle.

Features of removing the radio from NissanConnect

Versions Qashqai J11 with multimedia system NissanConnect (5" or 7" screens have additional nuances:

• 🔧 Additional screw hidden under the plug to the right of the screen (you need to pry it off with a spatula).
• 🔌 CAN bus connector (C) is expanded here - it has wires for climate control through the screen.
• 📡 Antenna cable can be screwed to the radio body with a small screw (do not pull it by force!).
• 🔄 After installing a new radio You will need to re-flash the CAN adapter for the steering wheel buttons to work correctly.

If you remove the radio to replace it with abnormal (For example, Pioneer or Alpine), please note that in NissanConnect A non-standard connector is used for climate control. Without adapter (Nissan M12) you will lose the ability to adjust the temperature from the screen. An alternative is to use universal CAN emulators (For example, Connects2 CTNI0002).

Checking connectors and diagnosing faults

Before installing a new radio or returning the old one to its place, be sure to check the integrity of the connectors. Here's what to do:

1. Visually inspect the contacts on oxidation or scorch. If there is a green coating, clean it with an eraser or a special liquid. Contact Cleaner.

2. Ring with a multimeter power wires:

   • Yellow — constant +12V (should be there even with the ignition off).
   • Red — +12V when ACC is on.
   • Black — ground (resistance to the body should be close to 0 Ohm).

Check integrity of audio wires. A common problem is a break in the rear speaker wires (they pass under the threshold and can fray).

If the radio did not turn on before removal, pay attention to fuse F37 (10A) in the block under the hood. It is responsible for powering the audio system and often burns out due to short circuits. Also check the relay R17 (in the cabin unit) - it controls the voltage supply to the radio when the ignition is turned on.

Installing a new radio: compatibility and adapters

When replacing the standard radio with universal (1DIN or 2DIN) you will need:

• 🔌 Connector adapter - for Qashqai J11 fits Nissan M12 (retains steering and CAN bus).
• 📏 Installation frame - for example, Metra 99-7513 for 2DIN radios.
• 🔊 Antenna adapter - if the new radio has a different connector (for example, ISO instead of FAKRA).
• 🎵 Amplifier — if you install a system without a built-in amplifier (in Bose it is external).

To connect a rear view camera in a new radio, use original video input (usually RCA). B Qashqai J11 the signal from the camera goes through a separate wire in the connector C — it needs to be soldered or an adapter used. If the camera does not work after installation, check the voltage at purple wire (should appear when reverse gear is engaged).

When choosing a radio, pay attention to CAN bus compatible. Supported Models Nissan CAN (For example, Pioneer SPH-DA130DAB or Alpine ILX-702D) allow you to save:

• Steering wheel control.
• Display information on the dashboard (for example, tracks from USB).
• Climate control operation through the screen (if an adapter is used).

Assembly and testing: what to check before turning on for the first time

After installing a new radio or returning the old one to its place don't rush to turn on the ignition. First:

1. Make sure all connectors tightly fixed. Check the connector especially carefully B (audio) - it should click when connected.

2. Secure the radio all screws (even if she “holds on anyway”). Vibrations during movement can weaken the fastening.

3. Connect negative battery terminal and check the voltage at the connector with a multimeter A (should be 12V on yellow and red wires).

4. Turn on the ignition and check:

   • The operation of the speakers (is there any wheezing or lack of sound in one of the channels).
   • Functionality of steering wheel buttons.
   • Display information on the dashboard (for example, the name of the radio station).

If after assembly the radio does not turn on, and the fuse F37 intact, check:

• Connection polarity — mixed up +12V and ground can damage the device.
• CAN bus — if the adapter is not flashed, the radio will not see signals from the steering wheel.
• Antenna cable - sometimes it moves away during installation, and the radio “does not see” the radio station.

⚠️ Attention: In the first batches Qashqai J11 (2014) there was a connector defect C — its plastic retainer broke when first removed. If you feel that the connector is “loose”, secure it with electrical tape or replace it with a new one (part number 28421-JM00A).

FAQ: answers to frequently asked questions

Is it possible to remove the radio without disconnecting the battery?

Technically yes, but highly not recommended. B Qashqai J11 The radio is connected to the CAN bus, and in the event of a short circuit, not only the fuse can burn out, but also the audio system control unit (Audio Unit). If you still take the risk, at least remove the key from the ignition and wait until the instrument lights go out (this means that the system has entered the “sleep” mode).

Why did the speakers stop working after removing the radio?

Probable reasons:

1. Broken wire in the connector B (especially if you pulled the wires).
2. Amplifier protection tripped (in systems Bose). Try disconnecting the battery for 10 minutes to clear the error.
3. CAN adapter is damaged - if the radio does not “see” the command to turn on the sound.

Check the speaker resistance with a tester (should be 2–4 ohms). If there is a break on one of the channels, the problem is in the wire or the speaker itself.

What adapter is needed to connect Android Auto?

For Qashqai J11 with NissanConnect suitable:

• Original adapter Nissan M12 + firmware for support Android Auto (for example, from NavTool).
• Universal CAN emulator Connects2 CTNI0002 - allows you to connect any radio with Android Auto without losing steering wheel buttons.

Please note: for correct operation Android Auto It may be necessary to update the firmware of the radio (for example, in Pioneer this is done through the manufacturer's website).

Is it possible to install a radio with a large screen (for example, 9-10 inches)?

Yes, but you will need:

• Replacing the center console to a modified one (for example, from Qashqai J11 2020 with a 9-inch screen).
• Climate control adaptation - in large radios, the climate buttons are transferred to the screen, and in Qashqai J11 they are physical.
• Flashing the CAN bus for compatibility with the new head unit.

Companies offer ready-made solutions Dynavin or Seicane — their radios come with frames under Qashqai and adapters for CAN.

What should I do if Bluetooth does not work after installing a new radio?

The problem is typical for Qashqai J11 with NissanConnect. Causes and solutions:

• Microphone not connected - in a standard system it is built into the radio, but in a new one it may require a separate connection (the wire is usually gray with black stripe).
• CAN bus conflict - some radios (for example, Sony XAV-AX5000) require disabling the standard Bluetooth module (located behind the radio).
• Activation required - in some models (for example, Alpine) Bluetooth turns on only after entering the PIN code (default 0000 or 1234).

Check your radio settings: sometimes Bluetooth is disabled by default in the menu Settings → Connections.
