How to properly remove the radio from a <em>Nissan Almera Classic</em>: instructions with photos and tips

Owners Nissan Almera Classic (especially models B10 And N16) sooner or later they are faced with the need to remove the standard radio - be it for replacement with a modern multimedia system, repair or diagnostics. The process seems simple, but has a number of nuances: from hidden fasteners to the risk of damage to the wiring. In this article we will look at step-by-step dismantling algorithm, we will list the necessary tools and warn about common mistakes that can result in expensive repairs.

It is important to consider that the design of the radio is Almera Classic depends on the year of manufacture and configuration. For example, in versions before 2006 there are often radios with non-standard ISO connectors, and in restyled models (2006–2012) - more universal fastenings. We will look at both options, and also give recommendations on working with wiring and connecting new equipment.

Preparing for dismantling: tools and safety precautions

Before you begin removing the radio, make sure you have everything you need. Wrong tool - the main cause of broken latches and scratches on the panel. Here's what you'll need:

• 🔧 Plastic mounting blades (2–3 pcs.) - for carefully prying off the panel. Use metal screwdrivers it's impossible, they will scratch the plastic.
• 🔌 A set of keys for removing the radio (if your model is equipped with them). For Almera Classic keys like this are often suitable DIN 75490.
• 📦 Phillips screwdriver (PH2) — to unscrew the panel fastening screws (if any).
• 🔋 Multimeter or tester - to check the voltage on the wires before disconnecting (optional, but recommended).
• 📸 Smartphone for photography — fix the location of connectors and wires before disconnecting!

Also prepare your workspace: disconnect the negative terminal of the battery (this will prevent a short circuit) and make sure there is enough light in the interior. If the radio is connected to the system CAN-bus (in models with an on-board computer), after disconnecting, the time and climate control settings may be reset - be prepared for this.

⚠️ Attention: If your Almera Classic equipped with a system Nissan Anti-Theft System (NATS), after turning off the radio, you may need to enter an unlock code. Check your instruction manual for this information. in advance!

Step 1: Removing the decorative panel around the radio

In the majority Nissan Almera Classic The radio is covered with a plastic frame, which is secured with latches. To remove it:

1. Insert a plastic spatula into the gap between the frame and the center console on the right or left side (usually there is less resistance there). Gently pry until you hear the latch click.

2. Repeat on the opposite side. Do not pull the frame towards you - first release all the latches around the perimeter.

3. If the frame does not budge, check for hidden screws under ashtray or climate control buttons (in some trim levels).

In models 2003–2005 the frame can be mounted on two self-tapping screws under decorative plugs. To find them, carefully pry up the plugs with a screwdriver (usually they are located on the bottom or top of the radio).

Step 2: Removing the radio from its seat

After removing the frame, you will see the radio itself, mounted either on four latches on the sides (in most cases) or self-tapping screws (rarely). Algorithm of actions:

• 🔍 Inspect the sides of the radio - there should be grooves for key removers (if they are included in the kit). Insert the keys all the way until you feel resistance.
• 🔄 Gently pull the keys towards you, pressing evenly on both sides. The radio should come out of the seat by 2-3 cm.
• 🖐️ If there are no keys, try to pry the radio with the lower or upper edges with spatulas, but don't try too hard - fastenings can be broken.

In some versions Almera Classic (for example, with a system Bose) the radio is additionally secured with a metal bracket. To remove it, you will need to unscrew two screws with a Phillips screwdriver.

⚠️ Attention: If the radio does not come out after using the keys, do not try to pull it out by force - this may damage the connectors on the rear panel. In this case, check whether there are additional fasteners at the top or bottom.

Step 3: Disconnecting Connectors and Wiring

When the radio comes out of the seat by 3-5 cm, you will see from behind one or more connectors:

• Main power and speaker connector (usually black or gray, standard ISO 10487).
• Antenna connector (coaxial cable with threaded connection).
• Additional connector (in systems with CD changer or Bluetooth module).

To disconnect connectors:

1. Take a photo of their location - this will help with reassembly.
2. Press the connector latches (usually plastic latches on the sides) and gently pull them towards you. Don't pull the wires!
3. Unscrew the antenna connector counterclockwise (if it is sour, use WD-40).

If the radio is connected via non-standard connector (for example, in earlier versions Almera Classic B10), may be required ISO adapter to install new equipment. In this case, write down the wire colors and their purpose (see table below).

Typical problems and how to avoid them

When dismantling the radio in Nissan Almera Classic Owners most often encounter the following difficulties:

• 🔌 Soured connectors — if the machine was operated in a humid climate, the contacts may oxidize. Solution: Process WD-40 or alcohol before turning off.
• 🔧 Broken latches — if you pull the radio without keys, the plastic latches break. Solution: Use only plastic spatulas and key removers.
• 📡 Antenna problems — in some models the antenna connector becomes stuck. Solution: Do not apply force, but first treat the joint with a penetrating lubricant.
• 🔒 Locked radio - after turning off the power, a code may be required. Solution: check with the previous owner or service Nissan (vehicle VIN required).

Another common mistake is wiring damage when forced to remove connectors. If the pins become bent, it may result in a short circuit or non-functioning speakers. To avoid this, always disconnect the battery before work and use pliers with insulated handles for careful removal of connectors.

Installing a new radio: compatibility and connection

If you remove the standard radio for replacement, consider the following nuances:

• 📻 Seat size - in Almera Classic standard is used 1DIN (height 50 mm). For 2DIN-The radio will require modification of the panel.
• 🔌 Connector compatibility - if the new radio has a standard ISO- the connector is non-standard in the car, buy it adapter (For example, Nissan to ISO).
• 🎵 Sound amplifier - in versions with Bose The signal to the speakers goes through an amplifier. When replacing the radio, it may be necessary lineman (bypass).
• 📱 Support for modern features - if you want Apple CarPlay or Android Auto, make sure that the new radio supports these protocols.

To connect a new radio, follow this diagram:

1. Connect power connector (yellow wire - constant +12V, red - +12V from ignition, black - ground).
2. Connect the speaker connectors, observing the polarity (usually the wires are marked: gray - front left, white - front right, etc.).
3. Connect the antenna and additional modules (for example, USB or Bluetooth).
4. Install the radio in the seat, fixing it mounting frame or keys.

⚠️ Attention: If, after installing a new radio, the buttons on the steering wheel stop working (in models with SW Control), will be required Save Control Adapter (For example, Pac SWI-RC).

Frequently asked questions after replacing a radio

❓ Why doesn’t the sound work after installing a new radio?

There may be several reasons:

• The speakers are not connected correctly (check the polarity and integrity of the wires).
• The sound in the radio is turned off in the settings (go to the menu Audio Settings).
• If the car has an amplifier (for example, Bose), it may need to be configured or a crawler.

❓ How to reset the radio code after disconnecting the battery?

If the radio is locked:

• Find the code in the car documents (usually in the service book or on a card stuck to the radio).
• If there is no code, contact the official service Nissan with the car's passport (VIN required).
• For some models, the code can be calculated using the serial number of the radio (look for it on the sticker on top of the device).

❓ Is it possible to install a radio with a rear view camera?

Yes, but you will need:

• Buy a camera with a viewing angle of at least 120° and protection IP67.
• Lay the video cable from the trunk to the radio (preferably through the ceiling or thresholds).
• Connect the camera to the connector RCA on the radio and set up automatic activation in reverse gear (you need a wire from the reverse light).

❓ Why does the new radio turn off when the engine starts?

This occurs due to incorrect connection red wire (+12V from ignition). Solutions:

• Check that the red wire is connected to ACC or IGN (and not to constant +12V).
• If the radio still turns off, install delay relay or connect it directly to the battery (but then it will discharge it).

❓ How to remove the radio if the key removers are broken?

If your keys are broken or lost:

• Use two flat screwdrivers, inserting them into grooves instead of keys. Be careful not to damage the housing.
• As a last resort, you can drill out the plastic clips inside the grooves (but this will damage the radio).
• Contact a car service - they have special pullers for such cases.
