Replacing the radio on a Nissan Note E12: a detailed guide with photos and tips

Replacing the standard radio with Nissan Note E12 - a challenge faced by many owners of this compact hatchback. The reasons may be different: from the desire to get modern functions (Apple CarPlay, Android Auto, navigation) to the banal failure of the original head unit. In this article we will analyze the entire process from choosing a new radio to its installation and configuration, taking into account all the nuances of a particular model.

It is important to understand that Nissan Note E12 (2012-2020) has unique connectivity features that set it apart from other vehicles of the brand. For example, some trim levels use a non-standard antenna connector, and steering wheel control requires an additional adapter. We will go into detail on these points so that you can avoid common mistakes and save time.

If you have never worked with car electronics, don’t worry - with the right approach and preparation, replacing a radio does not require professional skills. The main thing is to follow the instructions and take your time. And for those who already have experience, the article will contain useful life hacks, for example, how to do without adapters or where to buy original frames for a perfect fit.

Choosing a new radio: what parameters are important for the Nissan Note E12

The first and most important step is choosing a head unit. Not only functionality, but also ease of installation depends on this. For Nissan Note E12 Two sizes of radios are suitable:

• 📏 1DIN (178x50 mm) - standard size, suitable for most universal models. However, in this case, you will have to purchase an adapter frame, since the standard place is designed for 2DIN.
• 📺 2DIN (178×100 mm) is the best option, as it completely replaces the original radio without additional modifications. Most modern multimedia systems (with touch screen, navigation) are produced in this format.

When choosing, pay attention to the following parameters:

• 🔌 Connector Compatibility: U Nissan Note E12 a standard ISO connector is used for power and speakers, but the antenna connector may be non-standard (most often - FAKRA). Check this in advance or choose a radio with a universal antenna input.
• 🎵 Steering wheel control support: If your car is equipped with steering wheel buttons, you will need an adapter (for example, Metra ASWC-1 or Pac SWI-RC). Some radios (for example, Pioneer SPH-DA130DAB) have built-in support for such adapters.
• 📱 Smartphone integration: For Apple CarPlay and Android Auto, choose models with official support (eg. Sony XAV-AX5000 or Alpine iLX-W650). Please note that some Chinese radios may have problems connecting to the iPhone.
• 🔊 Output power: If you do not plan to install an amplifier, choose a device with a power of at least 50 W × 4. This guarantees good sound without distortion.

Popular replacement brands include:

• 🏆 Pioneer - reliable models with good sound and support for all modern functions. For example, Pioneer DMH-Z5350BT with wireless CarPlay.
• 💰 Sony — optimal price/quality ratio. Model Sony XAV-AX1000 often chosen for ease of operation.
• 🛠️ Alpine - premium solutions with excellent sound processing. Alpine Halo9 iLX-F409 suitable for music lovers.
• 🌍 Chinese brands (For example, Xtrons, Eonon) - budget options with wide functionality, but sometimes suffer from build quality.

⚠️ Attention: If your Nissan Note E12 equipped with a system Bose, make sure that the new radio supports operation with an external amplifier. Otherwise, the sound will be distorted or absent altogether. For such cases, you will need an amplifier bypasser (for example, LC2i from AudioControl).

Required tools and materials for replacement

Before starting work, prepare everything you need. The absence of even small things (for example, a plastic spatula) can complicate the process. Here is a complete list of tools and materials:

Category	Name	Note
Tools	Plastic paddles (or picks)	For removing the panel without scratches
Tools	Phillips screwdriver (PH2)	For mounting the radio and frame
Tools	10 mm socket wrench	To remove the brackets (if necessary)
Materials	ISO adapter for connection	If the new radio is not compatible with the original connectors
Materials	Antenna adapter (FAKRA → standard)	If the connectors do not match
Materials	Double-sided tape or mounting frame	For fixing a 1DIN radio in a 2DIN compartment

Additionally you may need:

• 🔧 Multimeter — to check the voltage on the connectors (especially if the radio does not turn on after installation).
• 🔌 Crimp terminals — if you have to resolder the wires (for example, to connect a rear view camera).
• 📦 Organizer for hardware - so as not to lose screws and clips during disassembly.

If you are installing a radio with support for a rear view camera, think about the cable route in advance. B Nissan Note E12 It’s most convenient to pull the wire along the left side of the cabin, hiding it under the trim and sills. For this you may need dismantling loop (sold in auto stores).

⚠️ Attention: When purchasing adapters and adapters, pay attention to the year of manufacture of your car. For example, in restyled versions Note E12 (after 2016) a different connector can be used for steering wheel control. Check with the seller or check by VIN code.

Removing the standard radio: step-by-step instructions with photos

The process of dismantling the original radio Nissan Note E12 takes about 30–40 minutes if done carefully. The main thing is to take your time and not use excessive force to avoid breaking the plastic clips.

Step 1: Turn off the power

Remove the negative terminal from the battery to avoid short circuit. This will also reset the radio settings (if it was protected with a code, you will need to enter it again after connecting a new one).

Step 2: Remove the decorative frame

The frame around the radio is secured with latches. Carefully pry it with a plastic spatula from the lower right corner and pull it towards you. If it starts to snap off, continue around the perimeter. Be careful: the clips are fragile and easy to break.

Photo of the frame removal process

The image shows that the frame is secured with four clips at the top and two at the bottom. If the frame does not budge, check to see if there are any unnoticed latches.

Step 3: Unscrew the screws securing the radio

After removing the frame, you will see four screws (two on top and bottom) that secure the radio in the socket. Unscrew them with a Phillips screwdriver. In some configurations, the screws may be hidden by plugs - they need to be pryed off with a knife or spatula.

Step 4: Remove the radio

Gently pull the radio towards you - it should come out of the socket. Do not pull too hard: the connectors are connected at the back. If the radio does not work, check that all screws are unscrewed.

Step 5: Disconnect the connectors

On the back of the radio you will see:

• 🔌 Main ISO connector (power + speakers).
• 📡 Antenna connector (maybe FAKRA or standard).
• 🎛️ Steering wheel control connector (if any).

Carefully disconnect all connectors, remembering or photographing their location. If the wires are stuck, do not pull - it is better to gently rock the connector from side to side.

Step 6: Check the contents

In some versions Nissan Note E12 The radio can be connected to the climate control unit. If this is the case, do not try to separate them by force - first study the connection diagram.

Connecting a new radio: diagrams and nuances

Connection is the most critical stage. Errors here can lead to a short circuit, failure of the radio, or even a fire. We will look at two options: using adapters and direct connection.

Option 1: Connect via ISO adapter (recommended)

This is the safest and easiest way. You will need an adapter that is suitable for Nissan Note E12 (For example, Metra 70-7552). Connection diagram:

• 🔴 Red wire (ACC) → +12V with ignition on.
• 🔵 Blue wire (ANT) → +12V constant power (for memory).
• 🖤 Black wire (GND) → Weight (minus).
• 🔊 White, grey, green, purple → Speakers (front and rear).

Option 2: Direct connection (for experienced)

If you decide to do without an adapter, you will have to connect the wires manually. Here is the color match for Nissan Note E12:

Car wire color	Purpose	Color of the wire on the radio
Yellow	Constant +12V	Yellow or orange
Red	+12V with ignition on	Red
Black	Weight	Black
Green	Right front speaker (+)	Gray
Green with black stripe	Right front speaker (–)	Gray with black stripe

To connect the wires use:

• 🔧 Crimp terminals - reliable, but requires special tools.
• 🔥 Soldering - the most reliable option, but it takes a long time.
• 🧲 Scotch locks - fast, but less reliable (may oxidize over time).

B Nissan Note E12 after 2018, a CAN bus can be used to transmit data on engine speed and rpm. If your new radio supports this function (for example, to adjust the sound depending on the speed), you will need an additional CAN-bus adapter.

⚠️ Attention: Never connect yellow (+12V constant) and red (+12V from ignition) wires together! This will lead to battery discharge, since the radio will always be on. If you want the device to work without a key, use only the yellow wire, but then the radio will consume energy even when the ignition is turned off.

Installing a new radio and assembling the panel

When all the wires are connected, you can begin installing the new radio. There are several nuances here depending on its size.

Installing a 2DIN radio

If you have selected a device format 2DIN, the process is as simple as possible:

1. Insert the radio into the socket and secure it with screws (included in the kit).
2. Connect all connectors (power, antenna, USB, etc.).
3. Install the decorative frame (if included).
4. Secure the frame with clips.

Installing a 1DIN radio

For 1DIN device will require an adapter frame (for example, Pioneer SM-D210). Algorithm of actions:

1. Install the adapter frame into the standard socket and secure it with screws.
2. Insert the radio into the frame and secure it using the slide (included).
3. Cover the empty space under the radio with a decorative panel (you can use a plastic plug or arrange additional connectors there, for example, USB).

After installation, check:

• 🔊 Sound — turn on the radio or music, make sure all speakers are working.
• 📡 Antenna — if reception is poor, check the antenna cable connection.
• 🎛️ Steering wheel control — if the buttons do not work, configure the adapter according to the instructions.

If you installed a radio with a rear view camera, do not forget to connect it to the connector REVERSE (usually orange wire). Some models Nissan Note E12 The reverse signal can be taken from the reverse lamp (purple wire in the rear optics harness).

How to hide rear view camera wires?

It is convenient to lay the camera wire along the left threshold, hiding it under the trim. In the trunk, the cable can be secured with plastic ties to the standard wiring.

Setting up the radio after installation

After physical installation, the radio needs to be configured. This includes:

• 🔊 Balance and equalizer — adjust the sound to your preferences. B Nissan Note E12 Often there is a problem with bass due to weak standard speakers. Try reducing the bass frequencies in the settings.
• 📡 Setting up the radio — perform an automatic search for stations. If reception is poor, check the antenna amplifier (in Note E12 it is located under the rear roof trim).
• 📱 Connecting a smartphone — Apple CarPlay or Android Auto may require a firmware update for the radio. Download the latest version from the manufacturer's website.
• 🎛️ Setting up steering wheel controls — if the buttons do not work, reprogram the adapter (instructions are usually included in the kit).

For radios with navigation:

• 🗺️ Update the maps (for example, via Naviextras for devices Pioneer or Alpine).
• 📍 Set up your GPS antenna. B Nissan Note E12 it is convenient to place it on the dashboard).

If the radio supports displaying images on the head display (in versions with Around View Monitor), an additional video converter will be required, since the standard system uses its own data transfer protocol.

⚠️ Attention: In some radios (especially those made in China), after connection, the overvoltage protection may be triggered and the device will reboot. This is due to unstable voltage in the on-board network Nissan Note E12. The solution is to install a voltage stabilizer (for example, LC-PWR) or connect the radio through a noise filter.

Common problems and their solutions

Even with careful installation, problems may occur. Let's look at the most common ones and how to eliminate them.

Problem	Possible reason	Solution
The radio does not turn on	Incorrect power connection or blown fuse	Check the fuse F30 (10A) and correct connection of the yellow and red wires
No sound	Unconnected speakers or incorrect polarity	Check the connections of all speakers, especially the rear ones (in Note E12 they are often connected via an amplifier)
Steering wheel buttons don't work	The adapter is not configured or the CAN bus connection is incorrect	Reprogram the adapter (eg ASWC-1) according to the instructions
Poor radio reception	The antenna amplifier is not connected or the cable is damaged	Check the power supply to the amplifier (usually comes from the radio via the blue wire with a white stripe)
The radio is rebooting	Unstable voltage in the on-board network	Install a voltage stabilizer or noise filter

If after installation there is noise in the speakers, most likely the problem is a bad ground. Try to clean the place where the black wire is attached to the body and re-attach it. Noise can also occur due to the proximity of the power cable to the audio wires - in this case, they need to be separated.

You can use a multimeter to diagnose faults:

• Check the voltage on the yellow wire (should be 12V constantly).
• Check the voltage on the red wire (should appear when the ignition is turned on).
• Check the speakers for a break (the resistance should be 4–8 ohms).

FAQ: Answers to frequently asked questions

Is it possible to install a radio with Android instead of the standard one?

Yes, but there are a few things to consider:

• 📱 Most Chinese Android radios (for example, Xtrons or Eonon) have non-standard connectors, so adapters will be required.
• 🔄 Firmware updates for such devices are rarely released, and lags may occur over time.
• 🎛️ Steering wheel controls may not work correctly (for example, not all buttons will be supported).

If stability is important to you, it is better to choose a radio from a well-known brand (Pioneer, Sony, Alpine) with Android Auto support.

Do I need to code a new radio after installation?

No, modern radios do not require entering a code after connection (unlike standard devices Nissan 2000s). However, if you are installing a used radio, it may request a code, which can be obtained from the previous owner or through the manufacturer's service center (the serial number will be required).

How to connect a rear view camera?

To connect a rear view camera:

1. Connect the camera to the connector REVERSE on the radio (usually orange wire).
2. Connect the camera video input to the appropriate connector (usually RCA).
3. Supply power to the camera from the reverse lamp (purple wire in the rear light harness).
4. Set up the radio: turn on the rear view camera function and calibrate the parking lines.

B Nissan Note E12 It is convenient to mount the camera above the license plate by drilling a hole in the plastic trunk trim.

Is it possible to keep the standard climate control display when replacing the radio?

Yes, but it depends on the configuration:

• 🔧 In basic versions Note E12 The climate control is mechanical and does not require replacement.
• 📟 In versions with automatic climate control (display in the radio), you will either need to keep the standard unit or purchase a separate display (for example, Metra Turbo2 for Nissan).

If you want to completely remove the standard display, you will have to reprogram the climate control unit, which is difficult to do without diagnostic equipment.

What should I do if, after replacing the radio, the parking sensors stop working?

This problem occurs if the new radio does not support the CAN bus. Nissan. Solutions:

• 🔌 Buy a CAN-bus adapter (for example, iDatalink Maestro), which emulates a standard radio.
• 🔧 Connect parking sensors directly to the radio (if it supports such functionality).
• 🚗 Contact the service to reflash the sensor unit (rarely, but it helps).

In most cases, the first option helps - a CAN-bus adapter.
