How to connect a Mystery car radio

Connecting a mystery radio

Car radios of the Mystery family can be classified as fairly inexpensive musical equipment, designed for use in cars with an on-board voltage of up to 14.4V and, at the same time, having quite decent indicators for the quality of reproduced sound and reliability.
However, in order for such a multimedia system to show its best side, one should not forget that installing a mystery car radio with your own hands requires the obligatory fulfillment of certain rules. First of all, it is necessary to remember that before starting any work related to interfering with the electrical circuit of the car, you should disconnect the “negative” terminal of the battery and, thereby, eliminate as much as possible the creation of conditions for the occurrence of short circuits during the process of connecting the car radio. In addition, the connection diagram for the mystery radio presupposes the presence of a universal ISO connector on your car, and in its absence, you need to pay special attention to observing the color markings of the connecting wires (however, in order to avoid annoying surprises, it would be useful to perform at least a selective “diagnosis” of this connector). You should also ensure that the negative terminals of the sound speakers are connected correctly, avoiding connecting them directly to the car body.

It is also not recommended to power the Mystery car radio directly from the battery, that is, bypassing the ignition switch - such a “simplification” of installation will lead to accelerated battery discharge, especially during long periods of parking.

As for installing the receiver itself, as a rule, a compartment on the dashboard designed specifically for these purposes is perfect for it. However, in any case, this place must be protected from direct sunlight, vibration and excessive dust. The angle of inclination of the front panel of the receiver should not exceed 30°.

To securely secure the receiver in the installation compartment, use the special frame included with the system, which is fixed in the niche by bending special metal “tongues”. Secure the receiver unit in the frame using a metal bracket and a 5x25 mm mounting screw.

If it becomes necessary to dismantle the receiver, this procedure is performed in the reverse order by inserting special keys from the kit into the installation grooves on the side walls of the unit.

Before final fixing the receiver, including installing the external decorative panel, connect all electrical connections using the diagram below and check the multimedia system for functionality. In order to initialize the system before connecting for the first time, use a thin object (for example, the tip of a ballpoint pen) to press the RESET button located on the cassette player. A similar procedure should be carried out in other cases of complete blackout of the car, in particular when replacing the battery.

Mystery MCD

For the best performance of the multimedia system, you need to follow some rules. Most Mystery radios have almost the same connection principle. However, in some situations they may differ between different models.

When purchasing from a dealer, you need to purchase a special adapter. It will simplify the installation of the car radio. You can cope with the task without an adapter. Additionally, you should take a multimeter or voltmeter. They will help determine the functions of the wires. You can connect the cable to the connectors based on the colors. The latter may sometimes not coincide.

1. Before starting installation, you must disconnect the negative terminal of the battery. This precaution is necessary to prevent short circuits during connection.
2. After reading the manual, you can proceed directly to installation. You must strictly adhere to the proposed scheme. If the wire is incorrectly connected, the device will work poorly or not function at all.
3. Connect the yellow or green wire to the positive terminal of the battery. The black wire is used for grounding. Bring it to mass. To power the red wire, it must be connected to the ignition switch.
4. Pinouts should be carried out taking into account the information provided. Similar shades of veins are often used.
5. Connect the blue wire to automatically activate the audio amplifier of the radio and antenna. The vein may have a white stripe.
6. The orange connector is used to connect to the terminal that controls lighting switching. Black and yellow is for remote volume control.

After aligning the inputs, connect the outputs. Connect such conductors to the speakers. Attach wires of identical colors to one column. Finally, check that the device is working properly.

Radio setup

If the question arises - how to set up a radio on a Mystery brand radio, then the manufacturer has greatly simplified the task for users and installed all the necessary modules for conducting a high-quality search for a radio signal.

All operations for searching and selecting a wave range are carried out automatically. All the owner of such a system needs to do is select the necessary settings and launch the program to search for radio channels.

To do this, on each model, both linear and touch, there is a corresponding key or inscription with the word “ Scan” . In order to select a suitable station for searching and playing, you must hold this button for 3 seconds. After this, a list of channels will appear where you can select the desired wave to configure and launch.

All Mystery brand radios operate in the following wavelength ranges:

To select the required wave, additional settings are required. The “ Band” button allows you to select the required range for searching. When pressed, it will be displayed on the screen of the device itself.

Mystery MMD

Some MMD versions may not have the black/yellow wire. There is simply no similar connector. The remote volume control function is not available in all cars. Its absence does not affect the quality of the device.

The conductors connected to the speakers deserve special attention. There is a thin black line in any pair of wires. It is used to designate the negative conductor. If you make a mistake and confuse it with a plus, low frequencies will not be heard. When playing back recordings, the bass will simply disappear. The speakers will start working out of phase. An error in the colors will cause an error in the balance adjustment.

The left front is connected with white wires. Gray ones are connected to the right front. The back left one is activated by green veins. Lilac is for the right.

Connecting a radio in a car without a connector diagram.

I came across this exhibit - radio cassette player Mystery MAR-818U (V5N10) car MP3 / WMA receiver, which must be connected to the car. This car radio has its own type of connector, with which a standard Euro / adapter is used, currently lost.

Anyone who has already watched the video of connecting a car radio Mystery MCD 664 MPU How to find the pinout of wires and connect a car radio without a chip - already has a primary understanding of the location and purpose of the contacts in the connector. Let's check if there is a difference between 818 and 664 models.

Patient car / radio Mystery MAR-818U with board PY-6618M3-MB (SPR) 4X7W (18P) 2014-07-04 REV: 03 06-106618-2004 appearance of the car radio receiver board in the picture.

The nameplate for connecting the car radio does not clarify the situation and does not contain the pinout of the connector / connection chip.

A simple opening of the car radio allows you to see on the back of the board the abbreviations for the names of the terminals connecting the radio to the car. Pinout of the connector/contacts in the photo. By the way, the markup contains an error. Instead of FL+ / FR- you should read FR+ / FR- . Car receiver outputs: NC (no contact), ACC (ignition) B+ (battery), GNC, FL, FR, RL, RR, ANT (power supply contact for active antenna).

After identifying the contacts for connecting the car radio receiver, you can close the case and begin the actual connection, but it’s too early to calm down. The flexible cable of the front panel is too hard and one of the terminals can easily break off, which will lead to a partial loss of functionality of the radio. After connecting, you should check the proper functioning of its operation and eliminate the detected defects (the radio panel goes out/does not light up, there is no power to the active antenna, the car radio does not turn on.) - if necessary.

Pinout of the connector on the body of the radio/receiver Mystery MAR-818U. For some reason, the ground is marked GNC instead of GND (was the paint worn off or a typo?) - in any case, the ground wire can be connected to the M5 screw on the rear panel, which is soldered to the board.

Correct connection of the car radio/cassette player ensures its reliable, safe and trouble-free operation during further use. So, final conclusions are needed and they are there. Perhaps most Mystery car radios adhere to the general standard connection connector; most - but not all (may depend on the board). The pinout of the connection connector will help to avoid unnecessary opening of the radio device and keep the front panel cable intact (you won’t have to study questions such as: how to fix / repair the cable; how to clean the cable; how to replace / solder the cable).

Useful tips

It is highly advisable to buy a licensed device. Then the kit will contain the necessary connectors with a cable to activate various options. These include power supply, acoustics, etc. When purchasing, you will need to take additional metal skids. They are necessary to connect the radio to the car panel.

Before installing the Mystery radio, it is recommended that you carefully read the attached manual and connection diagram. If you have doubts about your own abilities, it is better to seek help from a specialist. As an alternative, you can search the Internet and watch a video called “Connecting the Mystery Stereo System.”

What you will need

When purchasing licensed equipment, the kit comes with special connectors with wires designed to connect various functions: acoustics, power, and others. In addition, when purchasing along with the device, a person purchases metal slides, which are necessary for the car radio to be connected to the vehicle panel.

When purchasing from an authorized dealer, it is recommended to purchase a special adapter. It will make installation of the device easier.

However, it is possible to cope without having this device, although the work will become more complicated.

A voltmeter or multimeter may be required. Such devices will help determine the purpose of the wires. You can connect the wires to the connectors intended for them in the car by color, if they differ.

Turning on bluetooth

How to turn on bluetooth on the radio? There are two activation methods for this. Older Mystery head units use a special “Pair” connection button. It is located under the front panel in the lower right corner. To activate the synchronization mode with a mobile phone, you must hold this button for 4 seconds. After this, the indicator located next to it should light up.

The function allows you to answer and talk with the subscriber through the radio itself, without using a mobile phone. To answer an incoming call, use the “Talk” key. Modern models have the same button already on the front panel.

It is also possible to activate the synchronization mode and data transfer to the head unit through the settings. To do this, select the “Communication” item and find the “turn on bluetooth” tab. After this, you need to search for this device on your smartphone and synchronize with it. To communicate, you will need to enter the password both on the phone itself and on the radio “0000” and click connect. After a characteristic sound signal, you can listen to songs and communicate through the audio system.

Connection instructions

To connect the Mystery radio, you should first read the instructions. This will help avoid mistakes. It is important to adhere to the connection diagram; If this is not done, the device may function worse or not work at all.

Green (yellow) connects to the “+” sign of the battery. Black is intended for grounding; it should be brought to mass. To power the red one, it is important to connect it to the ignition switch.

The manual should provide a pinout. You need to connect the radio, taking into account the information provided. Differences in colors are possible for different models and brands. Most often, however, similar colors are used. You should not decide where to connect the cords yourself, as this may spoil the good sound quality.

Blue (possibly with a white stripe) is intended for automatic connection of a sound amplifying device and antenna.

The orange connector is required to connect to the lighting switch terminal.

Another connector of the Mystery radio is black and yellow: it is needed to remotely lower or turn off the volume.

This option is not available on all machines; sometimes there is nowhere to connect it.

In such a situation, the connector remains unclaimed; There is no need to connect it anywhere other than a special wire. This function does not affect the quality of the car radio.

When the inputs are combined, you need to connect the outputs. These are the wires that connect to the speakers. Cords of the same color should be attached to the same column.

In each pair, on one of the wires there is a thin black line, which indicates the negative cord.

If you confuse the plus and minus, or connect them incorrectly, the bass will not be heard when playing recordings, since the speakers will begin to play in antiphase. An error in color will lead to errors in balance adjustment.

White ones are intended for the left front. Those with a gray tint are connected to the right one located in front. For the rear left, green ones are used; for the right - lilac.

Post navigation

Connecting speakers This procedure is carried out carefully and carefully, since not only the purity of the sound depends on this, but also the operation and durability of the radio and speakers. MUTE Responsible for muting the sound when the button is pressed.

Sometimes there are two of them, and they control the operation of devices that operate only when the system is turned on. To ensure safety, disconnect the battery.

If the connector in the purchased radio does not match the car connector, then that’s okay too.

It will be better to use shrink sleeves and other precautions. Double-din radios are twice as large as single-din radios, which allows manufacturers to make models with a larger touch screen, as well as introduce more multimedia functions

Of course, the downside in this case is that the radio is in standby mode all the time. If the car does not have standard wiring from the battery, you will need a copper stranded wire with a cross-section of approximately 4.2 mm2.

Connections and installation of car radio

It is not recommended to connect the device to the cigarette lighter or ignition switch. Look in stores for an adapter for a multifunction steering wheel.

White ANT wire The wire with this marking is responsible for controlling the car radio's antenna. How to connect a car radio without getting tangled in the wires? Japanese, Korean and American usually work with 2 din - such models have 2 times the height, so the car must have a niche of the appropriate size. Connection method using an alarm Often the driver thinks whether I turned off the music in the car or not while parked. Thus, there are three main options for the procedure for connecting the radio yourself.

Connections and installation of car radio

Minimum wire length reduces resistance that distorts sound. Sometimes, if the phasing is not observed, some problems arise, namely, distorted transmission of low frequencies and bass. If your speakers are equipped with these types of connectors, you can use them to connect

The easiest way to connect

Subwoofer in the car

In this case, we mean the use of an active subwoofer, which does not require an additional amplifier. Started:

• We select a position for the subwoofer and supply power to this location. It is best done directly from the battery. If this is not possible, then as a last resort you can connect it through the cigarette lighter.

Note. It is very important to check everything correctly and maintain polarity. It is also important to additionally install a capacitor to power the subwoofer, so that when peak loads arise when playing low frequencies, problems do not arise.

• The subwoofer is connected to the car radio using a “tulip” wire or screw power contacts;
• After the connection is made, the setup will be reduced to limiting the upper limit of the speaker's low frequencies and selecting the speaker's oscillation phase.

How to connect a subwoofer

Note. Typically, many subwoofers have this feature.

A problem when connecting a subwoofer can be poor matching of amplitude-frequency characteristics. If you choose a subwoofer that has a special function that makes it possible to adjust the upper limit frequency using adjustment, then this would be considered as an advantage.

Advantages and disadvantages

How to connect an active Mystery subwoofer

The most important advantages of this active subwoofer are the following functions:

• It is equipped with a built-in amplifier, due to which an even higher sound level is achieved.
• This device is very compact in size.

Note. Due to this, it can be easily placed, as mentioned above, directly under the car seat.

• Thanks to the quality characteristics of this speaker, it is possible to reproduce sound with clear low frequencies. At the same time, due to this, the frequency of the sound will be slightly increased, which is why it will be clearer.
• The speaker costs very little - only 2500 rubles. But despite the price, it is very reliable.
• Its sale began in the Russian Federation in 2012. That is why purchasing such a device will not be difficult, since it is now quite common.
• And although the device has a very compact size, the sound quality can be called very good. That is, the subwoofer (see How to make a subwoofer: practical tips) has excellent sound output.

How to connect an active subwoofer Mystery

It has a stylish design (although this is not so important, because it will still have to be “hidden” under the seat). However, due to this, it can be placed near the rear window without any problems

But in no case will it affect the overall style of the car. The body is aluminum and very durable. As a matter of fact, you can be convinced of this only once you see this speaker.

Note. The speaker can easily withstand even the strongest mechanical shocks. And this is a fairly common occurrence, since the device is located directly under the car seat.

The remote control of any system perfectly controls the volume of the subwoofer. Also on its body there are several additional adjustments that facilitate the operation of the subwoofer itself.

Remote control that fits directly on the steering wheel

• The sub has an overload and power-on indicator, thanks to which the user can always understand whether the device has already booted up or whether it needs to wait a little longer.
• Suitable for any car as the speaker is universal.
• It is easy to connect, but this requires special knowledge.

Note. You can get them after reading our instructions.

This device has few disadvantages. But still they exist:

Connecting a subwoofer is specific, so you will have to tinker with it a lot.

Note. You should not purchase this subwoofer based solely on its price. This technique is perfect for those who are installing a subwoofer themselves for the first time. It will fit into a car that requires not too high acoustic parameters.

Connection via amplifier

This assumes connecting a passive subwoofer. So, let's begin:

• The first thing you need to do is connect the power. First, we connect the negative wire to the amplifier to the GND terminal. Don't forget to connect the other end of the wire to the car body.

Note. If you do not use a set of wires, but only pieces, then remember the following rule: the negative wire should always be thicker than the positive one!

• It is recommended to pay special attention to the cable cross-section. There is no need to skimp on good nutrition;
• We further connect the positive wire to the amplifier at terminal +12. Be sure to install a fuse, preferably as close to the battery as possible. It will protect against short circuit or sudden fire;
• In those places where the wire comes into direct contact with the metal of the body, it must be protected without fail. So, corrugations and bushings, as well as electrical tape, will cope with this task perfectly.

Note. We remember that connecting to the battery occurs at the very last moment.

• We connect with the REMOTE terminal. On all modern cars, or rather, in its head unit system, there is a blue wire with a white stripe applied to it. When the head unit is turned on, 12 volts are supplied to the wire and the amplifier turns on. Accordingly, if you turn off the car radio, the amplifier will also turn off. Convenient and safe.

Note. If for some reason there is no such wire, then the REM terminal is already connected to the ACC circuit. This goal implies such a position of the key in the ignition switch when only the radio works (typical for foreign cars).

• We carry out RCA cables. They connect the sound of the car radio with the amplifier (see How to connect an amplifier and subwoofer to a car radio: you are your own master). We try to lay these wires as far as possible from other cables and other sources of interference.

Note. If there is excess cable left, then it does not need to be twisted into a ring, but it is recommended to lay it in a snake.

If the Mystery car radio has one pair of line outputs, and the connection is to a 4-channel amplifier, it is recommended to use the Y-connector. Although with this connection the fader is lost. If the amplifier has an INPUT-SELECTOR, then this is the same Y-connector. We connect the subwoofer and this operation can be considered complete.

How to install and connect

The installation instructions for the radio contain the following recommendations to facilitate installation and connection of the device:

1. Before starting work, you need to turn off the power to the on-board network. To do this, remove the cable from the negative terminal of the battery.
2. Do not connect the negative terminals of the speakers to parts of the car body. The positive power cable for the audio system is routed through the ignition unit.
3. The connection should be made using the diagrams supplied with the instructions.
4. The head unit of the radio can be installed and configured with your own hands. For communication with the on-board network, a standard ISO connector is used.
5. The power part of the radio includes power cables connected to the battery and antennas. The woofers are connected to the auxiliary line outputs.

Connecting the Mystery subwoofer

Connect the mystery subwoofer to the radio

If you have a Mystery radio in your car, then there is a reason to connect a Mystery MBV-251A subwoofer to it. It is active and everything necessary for connection is included in its kit. Started:

• To begin with, it is better to check its operation at home. If the sound power is satisfactory, then everything is fine.

Note. It will also be useful to measure with a tester how much electricity this subwoofer consumes. As it turns out, when completely turned off, this subwoofer does not consume anything. When enabled, even if you turn off the bass, the speaker will consume power. Thus, it would be more appropriate to place the button on the control wire rather than on the thick positive wire.

• It's time to lay the wires. It is advisable to take the minus from the bolt securing the rear seat of the car and tighten it with a nut to ensure good contact.

Note. Laying a thick positive cable into the interior can be difficult. If you don’t want to drill the body, you can push it into the wiring harness going into the interior. In a word, decide for yourself - the easiest way is to make a hole with a drill and insert the wire.

• After the positive wire is inserted, you will need to connect it to the battery terminal (you can use a 10mm bolt);
• The remote bass control can be mounted directly above the fuse box. Here the regulator will not be conspicuous and the place is convenient, always at hand.

The installation should be carried out so that after turning on the head unit, use the button to turn on or off the subwoofer if it is not needed. Very comfortably.
