Wiring diagram for connecting speakers of the Lada Largus audio system

Lada Largus cars are available in several modifications, which differ in equipment. Basic versions do not have air conditioning and a standard head unit. Connecting a radio to a Lada Largus does not require the owner to have knowledge of electrical engineering or car design and can be done independently.

How to install

Some cars come from the factory with a 1 DIN car radio with CD player. Basic versions are equipped only with audio preparation; a plastic plug is mounted instead of the head unit.

To install the radio on Largus with your own hands, you need to:

1. After removing the plug, place guide slides with locks in the instrument panel.
2. Secure the mounting assembly using the tabs located around the perimeter of the part. Bending is done with a screwdriver; the installed shaft should not vibrate or make any extraneous sounds.
3. Connect the ISO connectors located on the standard wiring to the head unit.
4. Connect the antenna plug to the socket on the radio. If the sizes and shapes of connectors and plugs do not match, appropriate adapters are used.
5. Insert the audio device into the shaft and push it until it clicks, indicating that the latches engage.
6. Install a decorative frame around the radio panel.

Some owners install 2 DIN size radios on their Lada Largus. To place the head unit, it is necessary to replace the front plastic trim on the instrument panel, since it is impossible to accurately modify the original one.

The original panel is secured with latches, which can be removed manually or with a plastic screwdriver inserted into the gap between the parts.

The front panel with an extended window requires modification - it is necessary to install control buttons for additional equipment on it, borrowed from the Renault Logan sedan; original elements from Largus cannot be placed. This is due to the fact that the panel is designed for oval-shaped keys, which were never used on Largus.

At the same time, the mounting sockets for installing mounting clips are being finalized.

In the instrument panel, it is necessary to remove the horizontal jumpers located near the socket of the standard radio and climate control controls. Dismantling is carried out with a hacksaw and wire cutters, the remaining elements are cut off with a construction knife. All manipulations are carried out with caution, since there is a risk of damage to the standard electrical wiring. Then you need to reinstall the center console to assess the contact density of the elements.

Since the original wiring has cables with colored insulation that does not comply with the ISO standard, it will be necessary to compare the assignments of each element on the car and the radio. An adapter is used for connection; wire switching is allowed by twisting the necessary cables. It is recommended to reinforce the joints with tin-lead solder or a metal connecting sleeve. The connection point is covered from above with a heat-shrinkable tube, which provides protection from moisture and short circuits.

A budget option for replacing standard acoustics. Part 1.

When I first saw the Lada Largus, I immediately decided for myself: I will have it.

The sound from the standard speakers began to irritate me. .(

Less than a year has passed since the purchase of TRIFON, when the standard acoustics began to slowly “order to live long”! .) Strumming, metallic jingling, etc. began to appear. It all started with the front right speaker, then the rear left... And in order not to wait, it was decided to replace the standard speakers with something better than the standard ones. The budget for purchasing 2 sets of speakers was limited to $60. It was also decided to install speakers of standard size - 5.25″ (130mm). I turned to my friend. Outlined the situation. They inspected the speaker seats. The budget has been announced. And then it started. .) For the rear doors I was offered this kit: Coaxial speaker system DLS Matador M125G .

Characteristics: Type: Coaxial speaker Size: 130mm. (5.25″) Number of bands: 2 Rated power: 40 W. Maximum power: 60 W. Sensitivity: 90 dB (W/m) Frequency range: 60 - 20000 Hz Impedance: 4 Ohm

Tweeter Dimensions: 16mm. (0.63″)

Woofer Size: 130mm. (5.25″) Installation depth: 52mm. Installation hole: 120mm. (4.7″) Built-in filter.

I started replacing the standard acoustics. I started with the right rear door.

From above, I used a plastic spatula to pry off the standard protective mesh.

Released the top latch.

And carefully, pulling the protective mesh towards himself, he freed it from the hooks of the remaining latches.

I unscrewed the 4 screws that secure the speaker in the basket. And he took out the speaker.

This “miracle” is installed as standard acoustics.

As you can see in the photo, the standard speakers are connected with a specific chip (Renault). And in order to connect a third-party speaker system to the standard wiring, you need to buy special adapters! And since: “Our hands are not for boredom. ". And the price for these adapters is very steep, so I decided to make them myself. (Since I already took out one standard speaker, I made 4 adapters in advance.)

The recently purchased “nice thing” came in handy again.

Crimped and insulated with heat shrink casing - 4 adapters.

Let's continue. I disconnected (took out) the connector from the standard speaker and took the wires out of the chip.

And further. If you don't have a wiring diagram for the speaker system at hand. For ease of definition, so as not to guess where is the “+” and where is the “-“.

I connect and isolate the adapters.

And at the same time I wrapped a plastic chip with electrical tape. So as not to lose it in the garage, and... But what if. .)

There was also an incident with the installed speaker system. Due to the slightly wide petals (with which the speaker fits into the recesses of the cup and is attached to it with self-tapping screws), they fit very tightly into the regular places. And so that the diffusers are not damaged when dismantling them. I bent the petals a little.

How to connect a radio

Connecting the head unit depends on the vehicle modification. When installing the radio, you need to firmly snap the ISO plugs in place, and then reinstall the antenna connector.

If the product is equipped with a wired remote control, it is located on the steering column or the front of the instrument panel. The wire is laid inside the panel along the standard lines of the electrical harnesses.

With 2 speakers

The 2-speaker circuit is used only on cargo vans; the loudspeakers are located in the doors under the plastic panels.

The radio is ready for use immediately after connecting to the standard connectors. The car owner can install additional speakers in the cabin by laying separate speaker wires to them.

With 4 speakers

On passenger versions, 4 speakers are used, which improves the sound quality in the cabin. The wiring has a separate harness leading to the speakers in the rear doors.

The connection does not require any additional modifications to the vehicle wiring.

No speakers

The layout without speakers is found on the basic configuration. The car has connectors for connecting the radio and front speakers, as well as an antenna output. After switching the radio, you need to disassemble the door trims, which will allow you to mount the speakers in their standard places.

Loudspeakers are attached to factory mounting points, and wooden adapter rings may be used. After installing the elements, it is necessary to return the removed parts to their place.

Lada Largus is largely copied from models of the French brand Renault. And this applies not only to components and assemblies, but also to the standard radio. For example, the Renault Duster, Sandero, Logan models have exactly the same audio system head units. There is nothing surprising in this, because the assembly of these cars is completely organized in Russia. On Largus, the standard radio can only be seen in the “luxury” or “standard” configuration.

Pinout of Lada head unit

Among Lada drivers there is a special type of driver who constantly improves and refines the car’s audio system. Changing, often in a circle, a bunch of head units, eventually arriving at the point where the standard radio is put in place. If you belong to this type, or simply, for some other reason, removed the radio from its original place, and now want to return it, then our material today is for you! The pinout of the standard Lada radio does not hide anything particularly complicated; anyone with growing hands can handle it. Well, at least from somewhere. To begin with, we will have to deal with the wires, namely their color. Which wire will be responsible for some component of the car's audio system, and it would be advisable not to confuse them. Although in this case there will be nothing terrible and it is not forbidden to search at random. But there’s no need for you and me to wander around; we’ll figure out the color marking of the Lada wires right away. So let's get started.

Device characteristics

It can't be called complicated. In addition, the instructions and user manual supplied with the system will help you understand the structure, functionality and characteristics of the device. Structurally, a car can be equipped with either a conventional 1 Din or 2 Din radio. The differences between them are minimal and lie in the location of the buttons and inscriptions.

To reproduce high-quality sound, the audio system provides four speakers:

One of the main features and at the same time advantages of this device is the ability to connect to a smartphone via Bluetooth wireless channel. In addition to comfort and convenience, this function provides passive safety, since the Hands free system allows you to talk on the phone while driving without using your hands. The quality of communication is decent, communication with the interlocutor is not associated with difficulties, the driver does not need to raise his voice, and passengers hear him well.

Speakers in Largus size

When I first saw the Lada Largus, I immediately decided for myself: I will have it.

The sound from the standard speakers began to irritate me. .(

And the price for these adapters is very steep, so I decided to make them myself. (Since I already took out one standard speaker, I made 4 adapters in advance.)

Radio malfunctions and methods for diagnosing them

As you know, the Lada Largus is equipped with an audio system with a set of speakers already from the factory (depending on the configuration). The amplifiers are located in the front and rear door panels. To connect non-original speakers, several wiring harnesses are provided (including for increasing power using an amplifier when connecting a subwoofer). Since the connector plugs do not comply with the current standard, to connect another head unit you will need to additionally purchase adapters.

A standard car radio sometimes brings not only the pleasure of listening to music, but also some problems. The device may not work or function incorrectly for various reasons. In general, the list of faults includes only those that an ordinary driver (without special knowledge of electrical engineering) can fix with his own hands, without the need to contact a specialized center.

When it comes to repairs, it can often be cheaper to replace the device. Especially considering the availability of alternative options in different price categories and with different capabilities. At a cost of no more than 6,000 rubles, repairs can cost half this amount.

Connection diagram

The procedure for connecting the car radio may differ slightly due to the modification of the car. The audio device sometimes comes with a remote control. It is installed on the steering column or the front of the dashboard. The cable is laid along the length of the electrical harness lines.

The exact wiring diagram may vary due to the number of speakers. Therefore, it is advisable to remember the following information:

The speakers need to be fixed to the factory points. You can use wooden adapter rings. After installing the parts, the removed elements must be returned to their original place.

Firmware for audio device on Lada Largus

The standard head unit on cars of this model does not look very presentable, but at the same time the functionality is complemented by a large number of possibilities. Unfortunately, despite the decent quality of the technical part, the manufacturers did not pay enough attention to the software. It's no secret that modern audio systems have a full-fledged electronic control unit, which is a kind of computer. There is a processor, devices for reading removable media, various connectors and other functionality. In addition, the standard radio is combined with the on-board computer.

On the other hand, the more complex the audio system, the greater the likelihood of failures and malfunctions. The radio installed on the Lada Largus is no exception to the rule. The software has not been properly tested, so malfunctions are not uncommon. The most common problems are the inability to recognize the file format, reproduce high-quality sound, or identify the removable storage device. Also on Largus, incorrect display of Russian fonts on the display is often encountered. As a result, instead of the usual Cyrillic alphabet, the driver sees incomprehensible symbols. It is in these cases that updating the device firmware will help solve the problem.

Where to download and how to install

You can find out the firmware version directly on the device case, on the back side. The manufacturer regularly releases updated, i.e. improved firmware. You can find them either on the official website of the developer or on specialized thematic forums. If necessary, please contact your authorized dealer.

The firmware for the Largus radio is identical to the software from Duster or Sandero. At the factory, these cars are equipped with T2024 firmware (starting from 2014).

Preparation for the procedure

A firmware update may not be necessary if you try to reset the current settings to factory settings. The procedure is simple, but in most cases ineffective. If you update the firmware to a new version, you can expect a significant improvement in device performance. Typically, an official update is released rarely and always turns out better as testing is done and bugs are fixed.

The updated version V2030 was released in 2015. To install, you will need a flash drive or adapter with other removable media. Before you begin the procedure, you should prepare the media and find the appropriate firmware. You can download the firmware on the official AvtoVAZ website or on thematic official forums for Renault cars.

The file with the firmware is in the archive, so you need to first unpack it into a separate folder on your PC. The unpacked firmware provides a special archive that does not need to be unpacked further. The flash drive must be clean and formatted in FAT format. The unpacked CAB firmware archive is placed on it.

Update process

Now you can connect the media to the radio in your car.

1. Before starting the procedure, be sure to turn on the ignition. Otherwise, the radio will automatically turn off and the firmware process will be interrupted, which may lead to device failure.
2. When reading information on the media, the radio will determine that the contents on the drive are material for flashing. After analyzing the information, the device will offer to update the software. You should select "Yes" to refuse to click "No".
3. Confirm the information by clicking the “OK” button.

Step-by-step car radio firmware

First of all, it is worth remembering that updating the Lada Largus standard radio is a rather risky undertaking. After all, the manufacturer is not responsible for its possible outcome and excludes repairs under warranty in case of failure.

Step one

Before the actual flashing procedure, you can use the help of various resources, including the manufacturer’s website. Especially if this is a new version of the car radio model. In most cases, this procedure is provided free of charge, so offers for a certain cost should already alert car owners. After all, fraudulent actions will not only deprive you of money, but can also “reward” your device with malware.

Step two

In the instructions for the car radio you should find information about the version of the software currently installed. By the way, the same data can be displayed in the settings of the device itself.

Step three

Having found the necessary information, you can start installing the firmware. In this case, you should remove the radio from the dashboard and connect it to a personal computer. As you know, the latest models are equipped for this with a special connector called mini-USB. If you don't have one, an adapter wire is perfect.

Step four

After the radio is recognized by the computer, all the necessary software is downloaded to a separate folder and installed in the specified order. As a rule, this does not take much time - just a few minutes. This is due to the small amount of memory available, much less than that of standard computer applications.

Step five

When the flashing procedure comes to an end, the message “COMPLETE!” appears on the disk, which indicates automatic reinstallation after loading new data. If this does not happen, then turn off the ignition and remove the negative seal placed on the battery for 1 minute.

Step six

After turning on the car radio again, if the installation is successful, a prompt to enter a security code appears on the display. It comes in addition to newly installed files or is written in the instructions.

The only nuance that requires attention is the display of the caller's name when connecting a mobile phone to the car radio. Here the version of the number is simply changed to the international format, that is, the eight changes to a seven with a plus.

Some car owners use pre-downloaded programs, which are subsequently simply transferred to a disk or memory card. In this case, there is not even a need to remove the radio from the “socket” of the dashboard.

Exterior of standard car radio

To paraphrase a well-known saying, it should immediately be noted that in terms of taste and color characteristics you will not find two identical people. This also applies to the radio in the Lada Largus. Some owners will zealously prove its superiority, elevating it to the rank of ingenious devices, while others, on the contrary, will sarcastically criticize it, wanting to find more shortcomings. In general terms, we will say that the device harmoniously combines with the design of the panel and does not cause a feeling of rejection. Its functionality is convenient, and all elements (buttons) are located in optimal places, which allows you to make switches and other manipulations on an intuitive level. There are no backlashes, squeaks or other negative factors here. The fit is excellent.

Useful tips

Instead of a 1 DIN device, you can install 2 DIN on the Lada Largus. To accommodate it, you need to update the front trim on the dashboard. It is impossible to improve the original one. It won't look neat. In the panel, remove the jumpers located near the connector for the radio and climate control controls.

The front panel with a wide window will require some work. You need to install control keys for additional equipment. They are borrowed from Renault Logan. Elements from Largus cannot be placed. Initially, the panel was designed for oval buttons.

The original wiring has colored insulation. It is not ISO compliant, which means you will need to match the functionality of the items on the machine and on the device.

Sound via Bluetooth

A standard car radio in combination with dynamic speakers “reads” music programs equally well, “digesting” any genre without much difficulty. The manufacturer has addressed radio lovers with a powerful antenna device that allows them to pick up a signal of even minimal power. The radio allows you to memorize 6 stations in each frequency range.

Listening to music is available via CD drives or flash devices. Also for the same purposes, switching using Bluetooth is possible.

With a wireless connection, it is possible to rewind not only between music programs, but also directly within a track.

The display clearly displays the charge level indication (if “Bluetooth”), as well as the “RDS” line. There is a Russified font in “IDTag”.

Other methods of connecting to this device are the “Jack” and “USB” sockets.

Some owners are not satisfied with the lack of a removable decorative panel for the radio. We consider this point to be unimportant, since it is not able to protect against fraudsters.

Let's sum it up

In our opinion, the standard car radio present in the practical Lada Largus station wagon is very worthy in terms of its functionality and sound. This can be confirmed by many owners of this practical car, because there are a lot of positive reviews on this topic on the Internet. In addition, a convenient manual is included, through which “making friends” with the radio will not be difficult and will not require much time.
