Code for Lada Largus radio: how to unlock and how to enter the code, firmware

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.

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:

After removing the plug, place guide slides with locks in the instrument panel.
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.
Connect the ISO connectors located on the standard wiring to the head unit.
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.
Insert the audio device into the shaft and push it until it clicks, indicating that the latches engage.
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.

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.

Good afternoon. I have the same situation. The official Renault center could not help. Has anyone overcome this problem?

Why the hell are they needed then if there is so much hassle with them? Isn't it easier to buy a regular normal radio?

The dealer couldn't supply me with a new one under warranty because of this CONNECT DIAG TOOL - I need some kind of special cord for it, I ordered it and I'm waiting.

Hello. That's right. My 2 service centers in Volgograd could not start due to lack of cable. But I solved the problem. True, I had to send the radio tape recorder to Lipetsk. There is a specialist there who stitched it for 500 rubles. Fortunately, an acquaintance went to Lipetsk on business and I saved on shipping.

Can I contact this specialist from Lipetsk?

If you ever find the lady, let me know.

What's the issue with connectdiag here? Same problem.

The seller cheated, Bitch. He promised to help but doesn’t answer the phone. I found a person who can flash it, but I need a dump, which I haven’t been able to find yet. It lies like a dead weight, next to the amplifier that I wanted to install on this radio

What's the issue with connectdiag here? Same problem.

Well, in principle, for 3k, of course, it’s normal, but I don’t really understand this “staffing”, anyway, there’s nothing very good there. for 5-6k, it looks like the radio already had bluetooth, but at least the sound quality will be more or less there, but here there’s not even 1 pair of RCA? creepy.

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.

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.
Now, by pressing the “1” button, we achieve the first digit to appear on the display.
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”).
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.
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.

Entering the code

To decode the car radio on Lada Largus, you need:

Press the button with icon 1 located on the front panel to turn on the equipment. The display will show the text message Code, next to which there is a field like 0000 for entering a number. The first register of the code range must operate in flashing mode.
To enter the first number, you need to successively press key 1; the number of short actions corresponds to the value of the number. Input using a standard joystick is allowed.
To proceed to entering the second digit, you need to press the button marked 2, and the corresponding field on the head unit screen will begin to flash.
Enter the value of the number by analogy.
Program register 3 and proceed to entering the last character.
Press button 4 on the panel until the last digit of the password is displayed.
After entering, press and hold button 6 until the head unit controller reads the password and writes it into memory. Once the lock is unlocked, a short confirmation beep will sound.
Check the functionality of the device.

If an error was made when entering a number, a message like Code Error will be displayed on the screen. To try again, you need to wait 2 minutes; each subsequent error increases the pause by 2 times.

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.

We simultaneously press and hold the “1” and “6” buttons present on the keyboard (for 5-6 seconds).
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.
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.
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”.
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.
Now we confidently click on the “Generate” button, after which we get the code we need.
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.

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.

Main problems

If, when you press the power button, the head unit does not respond and does not turn on, then first of all you should pay attention to the mounting block, checking the 15A fuse in socket F28. Through it, the electrical memory circuit of the device is connected to the saved settings. The mounting block cover is located on the front panel on the left side at the end. You can understand that this fuse has blown by the absence of signs of operation of the instrument cluster panel, interior lighting and trunk lighting, since their electrical circuit is also powered by F28. If the fuse has not blown, the next check point will be the condition of the connecting contacts and the integrity of the wire that goes from the fuse to the A4 power connector on the back of the radio.

A common problem is no sound, i.e. the device itself turns on but there is no sound coming from any of the speakers when playing music.

In this case, the fault may also be the fuse, but F38. It supplies power to audio output devices. A faulty fuse is also indicated by a non-functioning cigarette lighter. If the latter works, then the fuse is intact. The lack of sound can also be caused by a violation of the integrity of the wire running from the fuse to connector A7 on the radio. And if only the rear speakers do not work, the culprit may be a broken connection in the block, which is located directly behind the driver's seat between the front and rear doors.

The cause of the malfunction may be the absence of ground - this is the black wire going to the radio (terminal A8). In all other cases, intervention in the electrical circuits of the device will be required. Without appropriate knowledge in this area, there is a high probability of complete failure of the radio. When contacting specialists, repairs can cost at least 1,000 rubles, not counting diagnostics.

Removing and installing the radio

If a device fails, you will need to dismantle it to install another one. Removal will also be necessary if it is necessary to connect speakers, repair, clean terminals or reflash. Visually, there are no latches or keys for removal on the front panel.

In fact, on the front of the radio there are four holes into which you need to insert 4 rods of suitable diameter (about 2 mm). The dismantling process is as follows.

Two rods are inserted into the holes on the left side.
Two more - on the right.
Now you should simultaneously press all the rods at once.
At the same time, pry it with a suitable plate, for example, a plastic card.
After characteristic clicks indicating that the latches are loosened, you can remove the device.

Installing the radio is even simpler: just insert it into the mounting socket and press until the latches fit into the grooves.

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.
