The first thing you need to do is when choosing a radio in a store, check its completeness. If the radio is different than the one you have now, then be sure to pay attention to the presence of an adapter included from the connector of the radio itself to a standard ISO connector - two wide two-row contacts, the connectors may be different, depending on the manufacturer (SONY, Kenwood etc.). Check with the seller whether additional adapters will be needed, telling him the make and year of your car; this applies in particular to foreign-made cars.

Everything you need has been purchased, you can start replacing. We remove and install it with the ignition off. You can remove the radio from the socket using special keys, which were included with the radio upon purchase. The keys for a new radio may not fit, so remember where the box or documentation for the old radio is, the keys are most likely there. Before inserting the keys, remove the outer frame and front panel radios. Having inserted the keys from the sides of the radio to the full length, pull it towards you, bringing the keys slightly closer to each other, the radio will come out along with the keys.

Half the job is done. Do not rush to disconnect the wires, they may fall behind the central panel, tighten them with an elastic band or a long wire that will remain outside, now they can be disconnected. Remember which wire was connected to which connector on the radio. Now remove the frame for installing the radio from the socket; it can simply be pressed with petals that need to be bent, or screwed with bolts or self-tapping screws (they must be carefully unscrewed).

Prepare a new radio, remove the installation frame from it and connect the adapter to the ISO connector. Having passed the connecting wires into the frame from the new radio, we install it in the socket for the radio, securing it in the same way. Check by hand that the frame is securely installed. Now you can start connecting the wires to the radio. Connect the ISO connector, antenna wire, additional wires if available. The antenna connectors are standard and have a corresponding icon next to them, just like other connectors not included in the ISO connector.

After all the wires are connected, you need to check the connection. Attach the front panel to the radio and insert it into the socket to the middle of the case. Turn on the power to the radio; if the backlight lights up, it means the radio is receiving power. Turn on the radio function and tune in to any radio station, after the radio broadcast starts, listen to each speaker separately, they should all work. Receiving radio broadcasts also means that the antenna is working and connected correctly. Then check the operation of the radio when playing sound from a disk and from a flash drive, if there is a USB connector. Now turn off the radio, remove the front panel and, using both hands applied to the sides of the front part, push the radio into the frame until it clicks. Install the front panel and outer frame. Now you can fully enjoy high-quality sound.

note

When connecting the radio, do not forget to “ground” it; the wiring is screwed onto the body of the radio, this way you will get rid of many problems during its operation.

Helpful advice

Sometimes you can’t pull out the radio with just the special keys; after inserting the keys, try to carefully pry off the top or bottom of the radio with a thin slotted screwdriver. After disconnecting the old radio, do not rush to remove the frame; perhaps the new radio will fit into it without the need to replace it with a new one.

In order to connect speakers to a brand new radio, you don’t have to go to a car service center and spend a considerable amount of money. If you have at least a little knowledge of electrical engineering, you can do this yourself.

You will need

• To connect the front speakers to the radio, you will need 6 meters of flexible speaker cable 2x0.75 mm, 2 rubber corrugations with a diameter of 14 mm with the outputs rotated 90 degrees. It is possible without turning, but then you will need to carefully wrap the wires with insulating tape so that they do not rub against the edges of the holes that you drill in the front doors, since the manufacturer did not provide any electrical wiring in the doors.
• To connect the rear speakers, you will need 11 meters of 2x0.75mm speaker wire. Here you can use a not very flexible cable, even a regular one, for home electrics of the PVS brand, will do. These wires will lie motionless throughout their entire service life, so they are not in danger.

Instructions

In the front door, directly under the top hinge, closer to the outer trim, make a hole with a diameter of 13mm. The second hole must be drilled 100mm lower so that when the door is opened, the wire turns and does not bend. Then it will last a long time. Try on how the wire will be positioned in the door, and mark with a marker the section of wire passing through the corrugation, with a small margin.

Wrap 5 layers of insulating tape around the exit points from the body and the door entrance.

Put on the corrugation and, using thin steel wire, tighten the wire into the door. Attention! In order not to damage the insulation, it is necessary to lengthen the wire to make it easier to run. The part of the wire that will go inside the body cannot be laid - the wire can be easily damaged there; it must be taped with insulating tape to general wiring.

Fold the eleven meter wire in half. Pull one of the ends out a meter and wrap the wires in this form with insulating tape. Cut the fold with pliers.

Now we need to lay the resulting bundle of wires in. It is better to lay along the threshold. For greater reliability, the section of the harness running along the floor can be tightened into a plastic corrugation for electrical cables. The part of the harness that runs directly along the rear shelf can be secured using plastic clips.

Also lift the section of the harness in the front of the car from the floor and tie it with insulating tape to the main wiring, and then lead it to the same place where the wires for the front speakers are already routed. In order not to have to look for which wire is which later, it is better to label them right away. For example, “front right” or abbreviated in English as FR. The rest: front left - FL, rear right - RR, rear left - RL. Do the same with all other speaker wires. After this, if the wires are the same color or without a stripe along the entire core, and it is impossible to distinguish between the conventional plus and minus in each pair, then the negative wire must also be marked.

When the wires are marked, check with a tester for a short circuit between the wires and, making sure that there is none, you can connect them to the connector and put the radio in place.

Then we check the speakers to ensure that their nominal impedance matches. Modern radios are compatible with speakers with a coil resistance of 4 ohms. If the device shows a resistance of 3.2 to 3.6 Ohms, you can install the speakers in previously prepared places and connect them to the speaker wiring. The main thing is not to confuse the polarity, otherwise there will be little bass. Make sure that the speaker terminals do not come into contact with metal parts of the machine.

When everything is connected, check the system is working.

Perhaps the first thing every owner who buys a car strives for is equipping the car interior with modern sound system. Musical compositions have the ability to reduce the driver’s stress while driving through city traffic jams, or cheer him up during monotonous driving along country highways.

Instructions

The place intended for installing a car radio in the front passenger compartment is usually closed with a plastic plug, which is removed, opening a niche for inserting a metal shaft into it, which is included in a pre-purchased set of radio equipment.

Having inserted the shaft, metal petals are bent outward along its perimeter so that, when bent, they do not prevent the radio from entering it. The petals of the shaft are made extended towards the base; their bend reliably fixes the shaft itself from spontaneous falling out along with the radio during movement.

After the shaft is inserted into the front panel, you need to connect the wires to the electrical connector of the car radio, which is also supplied. IN in this case guidance is required electrical diagram for each radio. Having studied the colors of the electrical wiring insulation, the wires are soldered to the terminals of the block, and then insulated with electrical tape.

Replacement head unit often causes difficulties for car owners. Below we will look at what breakdowns of the audio system can occur during operation, and how to properly replace and connect the device.

Below watch the video on how to replace the standard radio on cars Daewoo Nexia And Renault Megane 2 .

Basic malfunctions of radio tape recorders

Car radios with or without a subwoofer fail for a number of reasons:

• The radio does not turn on. This problem often occurs when Not correct connection devices. If the car owner does not have installation experience, he may confuse the “plus” and “minus”, which will lead to the fuse insert burning out.
• Sound amplifier failure. You can diagnose a malfunction by loss of sound in one or all speakers at once. In case of such a breakdown, as a rule, it is necessary to change the sound amplifier or repair the power supply circuit of the board.
• The linear output on the standard radio has failed.
• There is no backlighting of keys or screen. The problem can be explained by the burnout of the LED backlight or a group of light bulbs. As a rule, repairing a breakdown by a specialist takes a minimum of time.
• The drive mechanism is damaged. Depending on the type, the standard radio may be equipped with different types drive - for CDs, MP3 or USB output. In case of jamming or failure, the cause must be sought in this device. As a rule, failure is caused by wear and tear on the internal components of the system.

How to change the standard radio: instructions for action

The reason for replacing the standard radio can be many factors, including the lack of GPS navigation or USB input. If the decision is made, please note design features devices. On the audio system panel there may be buttons for controlling car systems - climate control, fan and others. That is why, when replacing a radio, preference is given to audio systems designed for a specific car brand. Fortunately, there are no problems with the assortment.

When incorrect operation standard radio and the impossibility of repairing it, the only solution is replacement. Let's look at how to do this job correctly below.

Do-it-yourself dismantling of the head unit

The process of removing the car radio may vary depending on the car model. But the general sequence of actions remains unchanged. To replace the standard radio, proceed as follows:

1. Remove the armrest in the car (if equipped). As a rule, the audio system is installed in the center console, and partial disassembly is required to remove it.
2. Press the top of the cup holder to remove the panel.
3. You will see two bolts - unscrew them and remove them.
4. Unscrew the bolts securing the beard. Please note that this element may be held in place using clips.
5. Unscrew the switches and controls, and then the climate control. Once these activities are done, put the “beard” aside.

As a result of the work performed, you will have access to the screws that hold the radio. Unscrew all the elements, after which you can dismantle the system. The wires connected to the standard radio must be discarded during the replacement process.

Installation and connection

If you are removing your old device and installing new audio system, it is important to know the principle and sequence installation work. Before replacing the standard radio and connecting it, prepare a connection diagram in advance (must come with the device).

Let's look at the audio system installation process using the Renault Megane car as an example. The algorithm of actions is as follows:

• After dismantling all the elements, begin the process of replacing the standard radio. First, place and secure the metal frame (“shaft”) of the device. To do this, press on it until you hear a characteristic click.
• After installing the “mine”, connect all the adapters that come with the kit to the ISO outputs. At this stage, be careful and act, taking into account the connection diagram that comes with the audio system - it should contain a detailed description.
• Place the radio casing. During installation, proceed with extreme caution. You must control the installation space to ensure that no foreign elements or parts get into it. Otherwise, you may encounter a number of difficulties.

Once this step of replacing the stock radio is completed, secure plastic parts center console that you removed earlier. If the car does not yet have speakers installed, they will also need to be installed. The wires necessary for connection must be laid, so all that remains is to bring them to the head unit and make the connection.

After replacing the radio, make sure it is installed correctly. To do this, turn on the device and check that it is working correctly, different modes. Turn the volume up to maximum and evaluate the sound quality - there should be no wheezing. It is important that the speakers work normally at all frequencies.

You decided to connect the radio yourself, but when you saw the number of wires coming out of it, you were afraid that you couldn’t handle it? In fact, there is nothing wrong with this, and in this article we will figure out how to connect a radio in a car.

What can you encounter if your car radio is not connected correctly?

It is impossible to say that for correct installation To use a radio tape recorder you don’t need any skills at all. It is advisable to have at least basic experience connecting electrical devices, but this is not prerequisite Following the instructions, a person can complete the installation even without any experience. To understand whether everything was done correctly, it is worth monitoring the operation of the radio. A sign of an error will be the presence of the following factors:

• The radio turns off when the volume is increased.
• When you turn off the ignition, the radio settings are lost.
• The radio drains the battery when turned off.
• The audio signal is noticeably distorted, especially when listening at high volumes.

In very rare situations, it is not the person who connected it who is to blame, but the seller who sold the low-quality product. Of course, this option cannot be ruled out, but you will still need to double-check the connection diagram.

Size and types of car radios

Universal radios have a standard size, it can be 1 – DIN (height 5 cm, width 18 cm) and 2 DIN. (height 10 cm, width 18 cm.) If you change the radio from large to small (from 1 – DIN, to 2 – DIN), you will need to buy a special pocket that will cover the missing din. In terms of connection, these radios all have the same connector, its name is ISO or it is also called a Euro connector.

1-DIN radio

Radio size 2 - DIN

Pocket for installing radio 1 -DIN

Standard radios are installed on cars from the factory and have custom size, in this case there are two options for installing the radio. The first is the simplest, you purchase the same standard radio and install it, it fits in size and connects to the standard connectors. But the cost of these radio tape recorders is often inadequate. And if you found a budget option, then with 100% probability it will be China, which is not particularly famous for sound quality and reliability.

The second option is to install a “Universal” radio in place of the standard one, but for this you will need an adapter frame, which is an adapter with standard sizes radios to universal ones, i.e. 1 or 2-DIN. the frame plays a decorative role, covering extra holes.

Hint for TOYOTA owners. In most cars of this brand, the standard radio has a size of 10 by 20 cm. In this case, you can look for “Spacers for Toyota radios”, they are 1 cm in size and you can install the radio without any problems standard size, i.e. 2 – DIN, to install 1 – DIN you will still need to buy an additional pocket.

Connecting the radio.

There are many cars, and each of them can use its own set of connectors to connect such equipment. Basically, there are three options:

1. Option one is the most favorable. You already have a chip in your car to which everything is connected correctly, i.e. All speakers, power wires, antennas are connected to this chip, and everything is connected correctly. This happens but, unfortunately, very rarely. This means that you are lucky, you just connect your brand new radio to this chip, and everything works for you.
2. The necessary wires are routed and connected, but the socket on the radio is different from the plug on the car.
3. There is no power lead out or it was done incorrectly.

With the first point, everything is almost clear. When the device socket does not match the connector, you will need to use an adapter. Despite the fact that these connectors are most often individual for each model, many companies practice supplying a separate ISO adapter. If there is no adapter or its format is not suitable in this case, you can either purchase such an adapter or twist the wires yourself. Of course, the second step is longer, more complex and riskier. Only technical centers that have experience in such procedures do this, so before you connect the radio in your car in this way, you need to think about everything very carefully.

Connecting the ISO adapter - Toyota

If you want to do the twisting yourself, you need to check the correspondence of the wires on the radio and the car connector. Only if the colors match can you disconnect the battery and disconnect the car and audio system connectors.

How to connect a car radio without getting tangled in the wires? It is recommended to bite off the remaining part after attaching the connector to the radio. All connections are soldered and insulated. If the wires do not match, you will need to check them using a tester or multimeter, as well as a 9-volt battery; you may also need to lay those wires that are not enough for connection. Ringing is necessary to determine the polarity of a pair of wires. When testing a loudspeaker, the wires are connected to the battery, after which you need to look at the position of the diffuser - if it extends, then the polarity is correct, if it retracts, you need to correct the polarity to the correct one. Thus, each wire is marked.

ISO - connector

Decoding the color code of wires

1. The negative of the battery is painted black, the wire is marked GND.
2. The battery positive is always yellow and is marked BAT.
3. The plus of the ignition switch is designated ACC and is red.
4. The left front speaker wires are White color, marking – FL. The minus has a stripe.
5. The right front speaker wires are grey colour, marking – FR. The minus has a stripe.
6. The left rear speaker wires are gray and marked RL. The minus has a stripe.
7. The right rear speaker wires are purple, marking – RR. The minus has a stripe.

How to properly connect a car radio?

First you need to purchase all the necessary wires. The wires must be made of pure oxygen-free copper and have silicone insulation. The yellow and black wires are power wires, the cross-section of these wires should be more than 2.5mm. For speaker wires and AAC (red), wires with a cross section of 1.2 mm are suitable. and more. Try to avoid a large number of twists, the ideal option is where there will be none at all, because... twists add extra resistance and this negatively affects sound quality and volume.

Connection diagram for radio and speakers

All radios have a black wire for the battery negative, yellow for the battery positive and red for the ignition switch positive. The car radio connection diagram is as follows - first it is better to connect the yellow and black wires, moreover, to the battery, which will allow you to get high-quality sound.
You will definitely need to install a fuse at a distance of 40 cm. The fuse must correspond to a minimum value of 10 A. The red wire is connected to the circuit, which is powered after turning the ACC key. When connecting the red and yellow wires together to the battery positive, the radio will not depend on the ignition, but the battery will discharge faster. Powerful radios have four pairs of wires, each of which has its own marking. When connecting a radio to a car, the polarity may be incorrectly determined - nothing bad will happen here, unlike grounding to minus to ground. The speakers have either two terminals, basically the speaker connection diagram is as follows: the wide terminal is a plus, and the narrow terminal is a minus.

Everything in our world of electronics is gradually becoming obsolete, and the car stereo ndash; certainly no exception. Just a few years ago, a high-quality radio with good sound ndash; was a real waste for the vast majority of motorists. Now any store selling radio tape recorders can simply overwhelm anyone with various offers, from the most expensive and high-quality radio tape recorders, to budget models. If you are planning to replace your old radio that was installed when you bought the car, then I will tell you how to do it!

Let's start with initial configuration car radios in the store ndash; If you buy a car radio of a different brand than the one that was installed in yours, then you need to check whether the radio comes with an adapter from its connector to a standard ISO connector. You can, of course, identify this very connector by looking at it. appearance ndash; it looks like twin wide double-row contacts. And on the radio itself, the connectors can be completely different; it depends on the model and manufacturer of the car radio. You can also try to check with the seller whether any other adapters are needed. Be ready to say old model your car radio, and your car's mag.

After this, you can proceed directly to replacing the radio. Keep in mind that all manipulations must be carried out with the car's ignition turned off. First you need to remove the old radio from the socket ndash; this can be done using the special keys that came with it when purchased. The fact is that the keys for removing the car radio are different, depending on the model of the car radio itself. Therefore, those keys that come with new radio, may well not be suitable for removing the old one. Therefore, you will have to look for the old keys. Before inserting the keys, you must remove the front panel of the car radio and the outer plastic frame. The keys are inserted from the sides of the car radio to the full length. After that, they need to be pulled towards themselves; thus removing the car radio from the socket.

Be careful with the wires: you shouldn’t disconnect them right away; It’s better to prepare an elastic band in advance in order to pull them together, because if they laquo;missraquo;, then they will fall far under dashboard, and it won’t be easy to get them out of there. After the wires have been tied with an elastic band, you can disconnect them from the old radio. You need to remember which wires connect to which connector. Next, you need to remove the frame to install the radio. It can be screwed to the socket with self-tapping screws, or it can simply be fixed with plastic petals.

Next, you should begin preparing the new car radio for its new location: to do this, you need to remove the installation frame from it and attach the ISO adapter, which should be included in the kit. The wires should be passed into the installation frame, and then the frame itself should be installed in the socket. Again, you need to look at how to install it ndash; screws or petals. After installing the frame, check that it is installed firmly and is not loose.

Now you can connect the wires to the new car radio. To do this, you need to connect the ISO, wires from the antenna, and other additional wires, if any. For example, this could be additional food. Look closely ndash; All connectors and wires have icons, so you can't go wrong.

That's it, the wires are connected to the radio. Now you need to check if everything is connected correctly. To do this, you need to insert the radio into the socket to the middle, and connect the front panel to it. After this, you need to turn on the car radio and check if the backlight comes on. Next, you need to check whether the radio is working ndash; This will check that the antenna cable is connected correctly. You also need to clarify whether each speaker is working, or maybe some are not working. Next, it is advisable to check the playback of music from the disk and the functionality of the USB. If everything works, then turn off the radio, remove the front panel, and with both hands completely push the radio into the slot until it clicks. Then return the panel to its rightful place.

That's it, the car radio installation is complete.

To remove from the car standard car radio, no special skills required. All that is required is a set of special keys supplied with the device. But what if there are no keys? Is it possible in this case to remove the radio from the niche without breaking it? This is what we will discuss in today’s article.

Removing the radio using standard keys

Before moving on to the process, we will list what is needed for this.

Required Tools

1. A standard set of keys supplied with the radio (there can be either 2 or 4 keys, depending on the device model).
2. Knife (if you have to pry off the frame).

Sequence of removing the car radio from the niche

1. The front panel of the car radio is removed, and if necessary, the decorative frame located under the panel is also removed (on older radios this frame usually blocks the key slots, on more modern devices this problem does not exist).
2. Provides access to key holes. They are located on the side walls of the radio.
3. Standard keys are inserted into the holes until they click. Sometimes this will require significant force, or slightly rocking the key left and right while pressing it into the hole.
4. After the keys are installed, the device is carefully pulled out of the niche.

Removing the radio without keys

Sometimes it happens that for some reason there are no keys. They can get lost, and in particularly difficult cases they are simply not included in the delivery package. In such a situation, you will have to use improvised materials.

Required Tools

1. 2 pieces of steel strip (length 30 cm, width 1 cm, thickness 0.5 cm).
2. Protective gloves.

Sequence of removing a car radio without keys

Video: removing the radio using two steel strips

Important points

• When removing the device from the niche, under no circumstances should you apply great force, as you can damage the wires located behind the radio.
• If steel strips are used to remove the device, they must be used only with protective gloves, otherwise it will not be possible to avoid cuts.
• Steel strips are far from the only available tool that can be used to remove a radio. Very often, car enthusiasts use old ATM cards or thin plastic rulers, from which “keys” are cut out using ordinary scissors. And sometimes even barbecue skewers are used to remove the radio.

So, you can remove the radio from the niche without keys. This can be done using available materials; fortunately, there is no shortage of them. If we are talking about modern radio tape recorders, then preference should be given to “keys” made of plastic, since the cases of these devices in most cases are also plastic, and metal tools can leave deep scratches on them.
