Largus head unit instructions

Many people spend a lot of time in their car. This is especially true for residents of megacities, because in order to get to work and back, they often have to sit in traffic jams. The Lada Largus car is equipped with a modern audio system that allows you to brighten up your time on the road. Let's take a closer look at what capabilities the standard radio in Largus has.

The radio installed in the car comes with a user manual, so it won’t be difficult to figure out how and what works. Schematically, the instructions indicate two devices: a double-din version and a standard one. The difference between them is mainly in the form of buttons and the inscriptions on them. Four speakers allow you to reproduce clear and high-quality sound.

The radio provides good sound through four speakers

The most useful and necessary characteristic of the radio is the ability to connect it via a wireless Bluetooth connection to a mobile phone. This is not only convenient and comfortable, but also safe, because now you can talk on the phone without using your hands. And the quality of such communication is quite decent, the interlocutor hears perfectly, and there is no need to shout.

Radio in action

It is clear that there is no friend for taste and color, as they say. Some people like the standard audio system, but others don't like it at all. Let's figure out what Lada Largus owners actually acquire along with the car.

Visually, the design of the radio tape recorder fits perfectly into the interior of the cabin. Its buttons and controls are quite convenient, and the symbols are intuitive. No loosening, backlash or failures are observed. Everything is adjusted very clearly.

Music in Lada Largus via Bluetooth:

As for playback, any genre of music will sound great. If you want to listen to radio stations, then an excellent antenna allows you to catch the signal even where it is too weak. It is possible to save certain radio stations in the amount of 6 stations in each band.

You can listen to music from existing CDs, flash drives, or simply from your phone or player via Bluetooth. The audio system reads formats such as CD, MP3, AAC, WMA and WAV. If this is Bluetooth playback, then pause and rewind control is available not only in albums, but also within songs.

The charge indicator of the Bluetooth device is visible on the display of the radio. There is also RDS - this is when the title of the song and its artist are displayed on the display. The device understands Russian fonts in ID Tag. The audio system has several options for connecting additional devices: Jack connector, USB connector and Bluetooth connection.

The radio has various inputs for reading music from external devices

Many car enthusiasts are not happy that the standard radio panel is not removable. However, there is nothing to worry about, because drivers often store the removable panel of their audio systems directly in the car, either in the glove compartment or under the seat. Therefore, if someone decides to steal a radio, it is unlikely that the main criterion when choosing a device will be the absence of a removable panel.

Summarizing all of the above, we can conclude that the standard radio in the Lada Largus car is quite good. It has a sufficient number of functions so that drivers do not have any difficulties when using it. And detailed instructions will help you easily master all the capabilities of this audio system.

5 Firmware for Largus car radio

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.

Secret menu of the Lada Largus audio system

You may know that on the Lada Largus, which is produced, the standard installed radio looks exactly the same as on the Duster and Sandero models from Renault - after all, they are also assembled in Russia. True, on Largus the radio tape recorder is installed only in the “standard” and “luxury” trim levels.

The product itself is quite good, and, despite its somewhat proletarian appearance, it is well assembled, nothing loose or sticks in it. Reproduction of sound and music is at a quite decent level, “buns” in the form of mp3, Bluetooth, ID3tag (Russian file names), Hands free, RDS are also present.

On the front panel of the radio on the left there is a SET button, which is responsible for using individual user settings. However, this key also has a number of undocumented functions. So, if you press this button and hold it for at least six seconds, you can get to a secret menu with additional settings. As already mentioned, there is not a word about this in the user manual.

After entering this menu, three new items will open: “Diagnostics”, “Radio Monitor” and “Device Configuration”:

You can move up and down items in this menu using the rotary knob on the right. Confirm your choice by pressing the same right handle.

If you need to return to the previous menu item at any level, you can press the “Back” button (it is located to the left of the right “spin”, which you control by moving the cursor around the menu).

When you select the “Radio Monitor” item, you can view the frequency of the radio signal of the received station, as well as a number of other parameters.

By selecting the “Diagnostics” menu item, a new submenu opens before us with the lines “Monitor”, “Errors” and “Autotest”.

The “Errors” submenu is designed to notify the driver about on-board computer errors occurring in the system. If everything is in order with the machine, when you enter this submenu the screen will be blank (therefore, there will be no errors).

By going to the “Autotest” menu, you will receive information about the status of the current equipment (if “OK” is visible in the line with the equipment, therefore, the equipment written in the line is working as expected:

Thanks for subscribing!

FM,AM Ant OK (Pas). Operation of the radio module (FM and AM range).
MICROPHONE OK. Microphone operation.
SPEAKERS OK. Is there sound coming from the speakers?
BT MODULE OK. Is the Bluetooth module working?
CD OK. The mechanical part of the CD player is in good working order.
FASIA BUTTON OK. Normal operation of car radio keys.
POWER IC OK. Operation of the on/off button.

If you go back and select the line called “Monitor”, the display will display basic information about the vehicle parameters.

This includes data on the network status, the status of the car's backlight (you can check the operation of this function by turning off or on the side lights of the car - the backlight status will change in real time to ON/OFF), battery voltage, USB device connection status , as well as about automatically decreasing/increasing the sound volume when the car speed decreases/increases (if the car has the appropriate wire for this function to work correctly).

In general, we dare to note that the undocumented menu of the Lada Largus car is really an excellent addition to the standard functionality of the audio system - we hope that it will not be difficult for you to understand its operation and the operating features of certain functions in more detail.

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.

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.

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.

How to unlock the radio? Radio code generator

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.

Radio malfunctions and methods for diagnosing them

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

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

When it comes to repairs, it is often cheaper to replace the device. Especially considering the availability of alternatives in different price categories and with different capacities. At a cost of no more than 6,000 rubles, repairs may cost half of this amount.

Main problems

If, when you press the power button, the main unit does not respond and does not turn on, first of all you need to pay attention to the mounting block, checking the 15A fuse in socket F28. Connect the device's memory circuit with the saved settings. The mounting block cover is located on the front panel at the left end. You can understand that this fuse is blown by the absence of signs of operation of the instrument cluster, interior and trunk lighting, since their electrical circuit is also powered by F28. If the fuse has not blown, the next check will be the condition of the connection contacts and the integrity of the wire going from the fuse to the A4 power connector on the rear panel of the radio.

A common problem is no sound, meaning the device itself turns on but there is no speaker output from any of the speakers when playing music.

In this case, the fuse could also be to blame, but F38. It supplies power to audio output devices. A non-functioning cigarette lighter also indicates a faulty fuse. If the latter works, the fuse is good. The lack of sound is also caused by a violation of the integrity of the wire going from the fuse to connector A7 on the radio. And if only the rear speakers fail, it may be due to loose connections in the unit, which is located directly behind the driver's seat between the front and rear doors.

The cause of the malfunction could be the lack of ground: this is the black wire going to the radio (terminal A8). In all other cases, intervention in the electrical circuit of the device will be required. Without proper knowledge in this area, there is a high probability of complete failure of the radio. When contacting specialists, repairs can cost at least 1000 rubles, not counting diagnostics.

Removing and installing the radio

If the device does not work, you will need to disassemble it to install another one. Removal is also required when connecting speakers, repairing, cleaning terminals or reflashing. Visually, there are no latches or keys for removal on the front panel.

In fact, there are four holes in the front of the radio 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 are on the right.
Now you have to simultaneously press all the rods at the same time.
At the same time, use a suitable plate, such as a plastic card.
After characteristic clicks indicating loosening of the latches, the device can be removed.

Installing the radio is even easier: simply insert it into the slot and press until the latches engage in the grooves.

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 code Largus how to find out

If you need to unlock the audio system of a Lada Largus car, then you should find out the PRE-CODE. Turn on the radio and press buttons “1” and “6” at the same time for about 5 seconds. The inscription “PRE-CODE XXXX” should appear on the screen; this code must contain one (first) letter and 3 numbers.

This code must be entered into the window of our calculator, click on the “Get code” button, then an unlock code consisting of 4 digits and instructions for entering it will appear.

Instructions

Usually a user manual is included with the radio. There are detailed characteristics of how it is used, what to press and when, and most importantly, why.

According to the diagram in the instructions, two versions of the radio are indicated:

There is nothing complicated about the first category, it’s just the name that is incomprehensible. These two versions differ only in different buttons and what is written on them. The most useful and practical feature is the ability to pair with some wireless devices via Bluetooth, such as connecting to a mobile phone. In this case, the standard radio on the Lada Largus will provide you with the opportunity to talk on the phone even without using your hands, thereby not violating traffic rules. If you think that you will have to talk very loudly or shout so that the interlocutor can hear clearly, then nothing like that. A normal tone of voice will be sufficient.

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. The radio tape recorder fits into its proper place tightly and without unnecessary play. The sound is also good, music for every taste sounds excellent and clear. The radio picks up the signal well, even if the reception is so-so.

Radio setup

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.

Level two. Replacing standard speakers

This is where you need to be very careful. This is a field with a rake; you can’t run with your eyes closed. This upgrade option is not always applicable. If you replace only the speakers and leave everything else, then it is far from a fact that the system will “sing.” Moreover, in some cases the result may be completely negative. Although the standard audio system itself is not of a high class, everything in it is matched to each other and balanced.

It is clear that the audio system is far from a priority element when designing a car, but sometimes the methods for installing standard speakers are simply surprising. The photo shows a standard BMW speaker, which was simply attached to the inside of the upholstery and covered with a light casing

One of the tricks that automakers resort to is reduced acoustic impedance. In general, the most common acoustics in car audio are 4-ohm ones, but in “standard” speakers they often use 2-ohm ones. All in order to boost the dead standard amplifier and slightly increase the volume headroom. Replace these speakers with more conventional 4-ohm ones and you get a quiet system, and any attempts to increase the volume will be accompanied by an increase in distortion.

But that’s okay, there are plenty of aftermarket acoustics with 2-ohm ones. Don't step on another rake - a corrected signal. This, by the way, is one of the “tricks” of many branded standard systems - it’s not the components that are better, but correction that compensates for the features of cheap speakers and the shortcomings of their acoustic design. Replace the dynamics in such a system, and such a correction will no longer be appropriate.

But there is no need to be scared and completely discard this option. Today you can find many acoustic kits that are tailored specifically for certain brands and models of cars. Mainly for European ones, in this part of the world such an upgrade is most in demand.

The video demonstrates the ease of upgrading a standard audio system by simply replacing the OEM speakers with a set specially designed for a specific car brand:

Replacing car radio Lada Largus

Suddenly you decide to replace the device. Or maybe you just want to clean it, change the firmware, install a code, or repair a tired standard device. Another relevant question arises: how to remove the Lada Largus radio without any visible external latches, keys and locks? If you have seen the removal process on Renault cars, then you know that there are four holes along the perimeter of the front panel. This is where the tricky latch and the answer to the question of how to remove it are hidden.

You will need 4 short rods at once, something similar to metal knitting needles or wire 2-2.5 mm thick. You need to first insert our two pins into the left side, and then the remaining two into the right. By simultaneously pressing all four, you need to pry the plastic card from below, and the radio will come out of its grooves. Now you can do anything with it: change the firmware, program the code, repair, etc. You will especially need this procedure when you disconnected the battery terminals.

After this procedure, you need to enter the code again, and if you don’t know it or don’t remember where you put the documents, you will need information from the back panel. There we will find a barcode, the last four characters of which we will need in order to generate a new code for the Lada Largus radio. It is advisable not to forget it. Without the correct code, the radio will not even turn on.

Firmware for Lada Largus radio

It was already mentioned a little higher that sometimes the radio needs new firmware. Why is it needed - you tell me. It's simple, at the factory setting our standard Lada Largus radio sometimes displays fonts clumsily, especially Cyrillic. Otherwise, she writes everything humanly, but in some options there are only hieroglyphs. This is where you will need to install updated firmware. How to make it? At one's own risk. If something goes wrong, all you have to do is remove and throw away the non-working device. It’s better to find out everything right away and find out before installing the firmware.

If the radio is still under warranty, flashing the firmware will void the warranty. In this case, why not remove it and take it to a service center and do everything wisely, without the risk of losing even those functions that already work well. Self-installation will also require certain skills. First you need to find out everything, find and download the firmware onto a flash drive. The installation will take place with the radio in place by pressing certain keys. The procedure itself will last several minutes. If everything works out and the installation finishes correctly, you will know about it right away.
