How to find out the radio code on Largus

The Lada Largus model is a joint brainchild of the designers AvtoVAZ and Renault-Nissan. Its design is based on the popular universal public car Dacia Logan MCV. When creating this car, the main focus was on the category of practical and family car enthusiasts, because the set of technical and operational features of the model fully correspond to its image.

The basic version of the equipment of the Lada Largus implies the presence of a standard radio, which the Korean company Daewoo kindly shared with Tolyatti residents. However, sometimes the firmware of the radio is required. In addition to the head unit, the developers addressed 4 loudspeakers located around the perimeter of the interior space, or rather in the door panels. Owners notice that this device fits harmoniously into the interior and has quite simple and convenient functionality. All controls and buttons are intuitive and do not cause “stupor” even for “wild” drivers. The high-quality fit of all components of the audio complex is also noted, since during operation it was not possible to find any backlashes or squeaks in the buttons.

To study in detail the full range of functions of this radio and how to control them, you should watch this informative and useful video:

Note that the consumer radio kit includes convenient instructions, which are designed to provide a quick acquaintance with the device and its functionality. In this article we will tell you how to unlock the Largus head unit.

Functions of the standard Largus audio radio

The audio device that is present in the Lada Largus allows the owner to acquire such useful options as:

• search and memorize radio stations broadcasting in the traditional FM or AM bands;
• the ability to display the names of tuned stations with a convenient “RDS” function;
• playback of audio programs recorded in the following formats: “MP3” and “WMA”, as well as “AAC” and “WAV”;
• connecting external sources to the head unit for the purpose of subsequent playback of information programs through standard speakers (for this, the radio has “USB” and “Jack” connectors, as well as a “Bluetooth” option;
• switching with the “Hands Free” wireless kit, which allows telephone communication with subscribers while driving.

Also, we should not forget about the presence of a security coding function in the radio, which allows you to increase the degree of protection of the device from theft attempts.

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.

Some car enthusiasts love their favorite car so much that they cannot live a day without it. And considering that many people live in huge cities, it takes a lot of time just to get to work and back. If you add traffic jams, you can spend almost half your life in a car. It’s good that at least the Lada Largus has modern acoustics at its disposal. This feature allows you to brighten up a little downtime in long lines, when your last nerves give out.

But it also happens that we have a standard Lada Largus radio, but understanding all its functions is not an easy task.

Coding of the original car radio

The standard Lada Largus device contains a set of protection functions that allow you to block attempts to turn on in cases where:

• the power supply from the on-board network (battery) is disconnected;
• the fuse-link protecting the device burns out;
• The radio is directly disconnected from the local power supply.

To be able to turn on a locked radio, you will need to enter a special four-digit code key. This code for the radio may be present in the service documentation attached to the device itself or simply be communicated to the owner at the time of purchase in the showroom.

Note that the code for the radio is entered using the keyboard, which is located on the front panel of the device.

Coding

The standard radio installed in the LADA Largus car is equipped with an electronic protection system that blocks its activation when:

• turning off the power supply (battery);
• disconnecting the radio from the vehicle's on-board electrical system;
• The fuse for the radio power supply circuit has blown.

In order to turn on a locked audio device, you must enter a special four-digit code, which when purchasing a new car can be:

• indicated in the service documentation;
• communicated to the owner at the car dealership where the purchase is made.

In order to decode the radio, you must enter a secret code using the keyboard located on the front panel of the audio device.

Entering the secret code

Entering the security code for the LADA Largus radio is carried out in the following sequence:

• turn on the audio device by pressing button 1 on the keyboard - the inscription CODE and a set of numbers “0000” should appear on the screen, the first of which will blink;
• by pressing button 1, ensure that the first digit of the code appears on the screen;
• the next digits of the code are entered in the same way, using buttons 2, 3 and 4 on the keyboard, respectively;
• after the entered four-digit code is displayed on the screen, you must press and hold button 6 of the keyboard for several seconds;
• If the code is entered correctly, the radio will immediately unlock.

Decoding

Decoding is a procedure during which the device’s security code is determined and it is unlocked. It is carried out in the case when the inscription CODE appears on the screen of the LADA Largus radio, but the owner does not know the secret code.

Enter the code. Step-by-step instruction

How to enter the code step by step. The input process itself involves following this sequence of manipulations.

1. We turn on the Lada Largus radio by pressing the “1” button in the keyboard field. In this case, an inscription appears in the form of “CODE” with the numeric dial “0000”. The first digit character will be in flashing mode.
2. Now, by pressing the “1” button, we achieve the first digit to appear on the display.
3. Entering the next digits in the code line is carried out in a similar way. However, this will require pressing the keyboard buttons corresponding to the serial number of the code digit (“2”, “3” and “4”).
4. Once you have completed entering all four code characters, you will need to press and then hold the “6” button, also located in the keyboard field.
5. Immediate unlocking of the radio will indicate that the code on the radio has been entered correctly.

Important! When the radio code is entered incorrectly, a message in the form of “CODE ERROR... WAIT” is displayed on the screen, after which a 2-minute time delay will be required. Then you can start re-entering.

Each subsequent input attempt, if it turns out to be incorrect, requires a shutter speed twice the previous time interval, etc.

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.

How to decode the head unit

The procedure involves determining the radio code, entering which allows you to activate the head unit in the Lada Largus. Such actions should be resorted to when the word “CODE” appears on the display, and the owner does not know its digital version. Let's consider the option of how to unlock the radio, as well as how to enter the code correctly.

Here you will need access to a special code generator applicable to Renault and LADA Largus radios. You can get this service by registering for free on the corresponding website on the network.

The decoding process involves an algorithm consisting of several stages.

1. We simultaneously press and hold the “1” and “6” buttons present on the keyboard (for 5-6 seconds).
2. After this, the display will display the inscription “pre code xxxx”, where the last four characters indicate that same “pre code”. It is necessary to gain access to the secret code combination, by entering which the radio will be instantly decoded. The radio code itself is formed from one letter and 3 numbers.
3. If this operation fails, you will need to dismantle the radio. For this purpose, you need to acquire two pullers “7711381821” or four pins. These devices are inserted into special holes present on the front panel of the audio device. Simultaneous pressing on the integrated removable components allows you to remove the radio from the landing shaft. Now disconnect the cable connector and antenna wire.
4. There is a sticker on the back wall of the device on which the manufacturer has applied a special barcode and other information related to this product. There you can also find the same “PRE-CODE”.
5. We go to a site with a code generator and enter the “PRE-CODE” read on the sticker into a special window for this service.
6. Now we confidently click on the “Generate” button, after which we get the code we need.
7. Next remains the method indicated by us to enter encoded information into the radio.

Attention! Before dismantling the device, we recommend disconnecting the power supply by removing the terminals from the corresponding terminals of the LADA Largus battery.

The principle of operation of the radio

You can't please all people. Some people like the original standard audio system that comes with a new car, while others want a more advanced option. So what is it like - the original Lada Largus radio? The appearance harmonizes very well with the interior design. Convenient control buttons help you quickly figure out what to press or scroll where.

You can play music from discs or via the Bluetooth connection of your smartphone. It should be noted that the quality does not suffer. Yes, and tuned radio stations can be recorded so that they do not disappear. In addition to disks, you can also use a USB connector, to which you can easily connect a flash drive and play music from it. The device reads basic formats perfectly.

You can rewind and pause even in the middle of a song without having to start over every time. The display shows information about connected devices if a song is playing, that is, the title and artist. In general, connecting devices and operating them is a simple task.

If necessary, you can connect to it, in addition to the above, also headphones via the Jack connector. Some people don’t really like that the outer panel is non-removable, like the previous options. But to think that this is not a problem at all, because if someone wants to steal it, then the absence of an external socket is unlikely to stop the attacker. And he didn’t come for her, but for the radio.

So, the Lada Largus factory head unit has a good set of functions. As soon as the thought arises that something is missing, you need to take the instructions and read them carefully. It is possible that we simply do not know about some possibilities.

Largus car radio firmware

When the owner of LADA Largus is dissatisfied with the standard functionality of the radio, then you can resort to firmware. The reasons prompting such actions may include failures of configured programs, failure of buttons to respond to the activation of specific functions, etc.

Important! When flashing the firmware of the radio, you should remember the responsibility for the subsequent performance of the LADA Largus radio. This operation is quite complicated and no manufacturer will provide warranty service for the radio if the owner decides to take such measures as flashing the radio's firmware. When an irresistible desire arises to carry out the firmware procedure, it is better to entrust it to specialists who have considerable experience in this field. Now you know how to unlock the car radio, as well as how to enter the code correctly.
