Replacing the radio with Nissan Almera Classic (body B10, 2006–2012) is a challenge that many owners face. The standard audio system is morally and technically outdated: no support Bluetooth, USB or Apple CarPlay, and the sound quality leaves much to be desired. However, the replacement process has nuances: from non-standard size 1DIN with additional frame to the specifics of connecting to the vehicle’s CAN bus.

In this article you will find detailed instructions for dismantling the old radio and choosing a new one (taking into account compatibility with electrical Almera Classic), as well as a step-by-step installation description. We will look at what adapters are needed, how to avoid mistakes when connecting power and speakers, and what to do if the buttons on the steering wheel stop working after replacement. Let's look separately at models with climate control - the process is more complicated there due to the integrated control panel.

Preparing for replacement: tools and components

Before you get started, make sure you have everything you need. Without the right tools and adapters, you risk damaging the connectors or leaving your car with no sound.

Minimum set of tools:

  • 🔧 A set of plastic mounting spatulas (for removing the panel without scratches).
  • 🔨 Socket wrench or socket on 10 mm (for radio mounts).
  • 🔌 Phillips screwdriver (PH2) and flat screwdriver (for dismantling decorative elements).
  • 📏 Ruler or caliper (for measuring the seat).

Installation components:

  • 🎵 New radio (size 1DIN or 2DIN with adapter).
  • 🔌 Adapter for connecting ISO connectors (for example, Metra 70-7302 for Nissan).
  • 🔊 Antenna adapter (if the new radio has a different connector).
  • 📱 CAN bus adapter (if integration with steering wheel buttons is needed).

Choosing a new radio: compatibility and dimensions

Seat in Nissan Almera Classic designed for radio format 1DIN (180×50 mm), but with nuances:

  • 📏 Depth: Maximum hull depth - 160 mm. Deeper models will not fit due to the location of the ducts.
  • 🔌 Connectors: A non-standard connector is used as standard Nissan, so you will need an adapter for ISO.
  • 🎛️ Steering buttons: For their operation you need a CAN bus adapter (for example, PAC RP4-NIS01).

If you want to install 2DIN- radio (with touch screen), you will need:

  1. Adapter frame for increasing the space (for example, Scosche NI2006B).
  2. Additional fastening for fixing the case (standard latches will not work).
  3. Relocation of the climate control unit (in models with an automatic system).
Radio type Compatibility Additional adapters Model example
1DIN (no screen) Full ISO adapter, antenna adapter Pioneer DEH-S4200BT
1DIN (with retractable screen) Partial (check depth) ISO, CAN adapter for steering wheel buttons Sony XAV-AX1000
2DIN (touch screen) With frame adapter ISO, CAN, frame Scosche NI2006B Alpine ILX-W650

Important: In radios with Android Auto or Apple CarPlay check protocol support MOST or CAN for correct operation with the on-board system Almera Classic. Some Chinese models (for example, Joying) may require firmware for compatibility.

💡

If you plan to use a rear view camera, choose a radio with a video input RCA and check the camera's power supply voltage (should be 12V, not 5V).

Removing the standard radio: step-by-step instructions

Removing the old radio is the most important step. Errors here can lead to damage to the connectors or reset the on-board computer settings.

Procedure:

  1. Disable negative battery terminal (required! This will prevent short circuit).
  2. Remove the decorative frame around the radio. It is attached with latches - use plastic spatulas to avoid scratching the panel.
  3. Unscrew the two screws securing the radio (located on the sides, under the frame).
  4. Carefully pull the radio towards you, disconnecting the connectors at the back. Don't pull the wires!

On the back you will see:

  • 🔌 Main power and speaker connector (black, 16-pin).
  • 📡 Antenna connector (coaxial, standard Motorola).
  • 🔄 CAN bus connector (if there are steering wheel buttons).

☑️ Preparation for dismantling

Done: 0 / 5
⚠️ Attention: In versions with climate control Nissan Almera Classic The radio is connected to the control unit via CAN bus. When disconnecting connectors do not touch metal parts of the body - this may cause climate settings to reset or an error U1000 in the on-board computer.
What to do if the radio does not come out?

If the radio is jammed, check whether the climate control frame is interfering with it. In some configurations, the fastenings may be hidden under an additional panel. Try to slightly rock your body left and right, while pulling towards yourself.

Connecting a new radio: diagram and adapters

The most common mistake when replacing is incorrectly connecting the connectors. B Almera Classic Non-standard pinout is used, so an adapter is indispensable.

Pinout of standard connector Nissan (16-pin):

Contact Wire color Purpose
A1 Yellow Permanent +12V (memory power supply)
A2 Red +12V (ignition)
A3 Black Weight (GND)
A4 Orange Panel lighting
B5–B8 Green/Purple/White/Grey Speakers (front/rear)

To connect a new radio, use an adapter Metra 70-7302 or similar. It converts the standard connector Nissan to standard ISO, which is supported by most radios.

Connection order:

  1. Connect the adapter to the radio connector.
  2. Connect the antenna adapter (if required).
  3. Attach the CAN adapter for the steering wheel buttons (if equipped).
  4. Check the polarity of the speakers (incorrect connection will result in distorted sound).
