Reviews

Vitaly, 32 years old, Vologda

I bought a Mystery MDD-6270NV radio in 2016 based on reviews from friends. After a year of operation, problems with performance appeared; the device periodically froze and required an emergency reboot. Later, the navigation module began to work incorrectly, and six months later the display turned off. Contacting the service center did not bring any results; I did not have time to purchase a new device because I sold the car. The new car has a standard navigation system, which I have no intention of replacing with a third-party product.

Denis, 42 years old, Tambov

I have been using the 6270NV radio since the fall of 2022. Registered on the Navitel website, which allows you to download new versions of software and area maps. I listen to the radio, connect external drives with music, but I have never watched a video. Signal reception by the radio is unstable; it is difficult to catch stations outside the city.

Instructions on how to set up a radio on a radio from various manufacturers

You can use a radio to pass the time on the road. Typically, drivers prefer to listen to music that is unobtrusive, so that it plays in the background and does not interfere with steering. An autoradio is most suitable for this, which first needs to be configured. But many people don’t know how to properly set up the radio on their car stereo.

Setting up the radio

Basically, setting up the radio consists of several simple steps. The broadcast range is selected and radio channels are searched and stored in the tuner’s memory. The search for radio stations occurs either automatically or manually. In the first case, radio channels are stored in descending order of broadcast quality.

Let's take a closer look at how to configure the radio on common car radios.

Pioneer

If you are wondering how to set up the radio on your Pioneer radio, don’t worry, setup is very easy. When automatically setting up the Pioneer, press FUNC, followed by BSM. To start searching for radio channels, press the right or up button; after finishing, the music of the first radio station found will turn on.

For manual installation in BAND mode, long press >>|. A search will be launched for any first station within this radius. After which the device will stop scanning and start playing the found station. Then you will need to save it; to do this, hold the key with the desired number for a long time. If you do not need the found station, you need to press the right key and hold it. Scanning will continue until a new station is found.

With this function, you can store up to 6 stations in the first bank. After this manipulation, press the BAND button and get into the second bank, it is shown on the display as F2. In the second bank, you can similarly store up to 6 stations in memory, and there is also a third bank. Most often there are three banks, but there are more. As a result, if you have three banks, you will have 18 stations active and saved. Now you know how to set up the radio on your Pioneer radio.

Setting up the radio in the Sony radio will also not be a problem. Searching for stations is usually carried out in two common ways: manually or automatically. Automatic memorization of radio stations:

1. Turn on the radio. Long press the Source button and wait until TUNER appears on the display.
2. The range is changed by pressing the Mode button. If you press the joystick, a menu of options will appear.
3. Rotate the joystick until the VTM option appears. Radio channels are assigned to numbered keys as standard.

To manually scan and save you need:

1. Turn on the radio and start searching for stations.
2. Once the desired radio station has been found, you need to press the number key from 1 to 6, after which the name “Mem” will appear. Note: when saving a radio station on a digital number that already has a radio station, the previous one is automatically erased.

Thus, you can set up a radio in a Sony radio in 5-10 minutes.

Supra

After pressing the MODE button, select the Radio function, then RADIO and the saved band with the broadcast frequency will be displayed on the screen. Pressing BND selects the desired broadcast band.

Next, you need to press the key with numbers from 1 to 6 to use the already saved radio station in the radio.

Press and hold the >>|| button.

The receiver will tune in to six optimal stations, which are the most powerful in this broadcast range. This option can be used in any wavelength range. Once the automatic saving of stations is completed, the receiver will stop scanning them.

To tune into a specific radio station, press the >>|| button, this will scan and select radio channels with the best reception signal. By pressing the >>|| button, you can manually select the station you want. Hold down the key numbered 1 to 6 for about a couple of seconds to memorize the channel under the desired key.

Installing stations manually:

1. Select a broadcast band by pressing the TUNER BAND key.
2. Click on button 4 to set the station.
3. Hold down the key with any selected number on the panel to memorize the station in the radio's memory. The selected number will start blinking, after which you will see the station stored under the selected number. For example: To tune to station number 14, press the +10 key, followed by the 4 key for approximately three seconds or more.
4. To store other radio stations in the device’s memory, you need to repeat steps one through three. And to change the settings of the entire station, you need to repeat the entire process from the beginning.

Specifications

A car radio can be called not just a practical, but also a stylish device. The design has been carefully thought out to ensure maximum user comfort.

The front panel is removable. This is done for security purposes, so even when the driver has to leave the vehicle, he does not have to worry about equipment theft. On the front panel there is an AUX output and a USB port, which allows you to listen to files from a flash drive.

The model is equipped with built-in amplifiers (4*50 W). This allows you to achieve powerful and clear sound. The driver can also use the 2 RCA preamplifier outputs to connect an additional stereo component, for example, an amplifier for the rear speakers.

The device is compact, its size complies with accepted standards: width - 17.8 cm, height - 5 cm, and installation depth - 16.0 cm.

The car radio is designed for an operating voltage of 11-14 V. The frequency range of the VHF tuner is 65-108 MHz, for a medium-wave receiver it is 522-1620 kHz. This model has 30 built-in memory cells for radio stations.

Installation

Before installing the radio, you need to check the electrical wiring and make sure that the vehicle systems are working correctly.

Although you can set up the receiver yourself, it is better to first consult with a specialist. Changes may need to be made (for example, additional holes need to be made). In addition, in order to install everything correctly, you should use the parts included in the package.

The radio must be installed so that it does not interfere with the driver while driving, and in the event of an emergency stop, does not injure the passenger.

The receiver frame is inserted into the corresponding compartment on the car dashboard. There are special “tongues” for installation. They do not all fit the compartment in size, so the user’s task is to select the necessary elements. It is convenient to bend them using a small screwdriver.

First, connect the receiver and only then mount its front panel.

Connection diagram

Before starting installation work, you should review the user manual. There should be a wiring diagram for the car radio. But even with the most careful study, many questions may arise.

If all the work related to the connection has already been completed in the car, that is, the wires have been installed, all that remains is to connect the radio as shown in the figure in the instructions. In this case, you can handle the task yourself.

If there is no power wire output, it is better to seek help from specialists. This is especially true in cases where the device socket and the existing connector do not match. Then you need to either look for a suitable conductor, or twist the wires in a special way, so that during the work the risk of errors increases.

Independent connection, even in a simple case, requires knowledge of symbols.

For example, the positive terminal of the battery is marked as “VAT” and is always yellow. The red tint is at a similar terminal of the ignition switch, designated as “ACC”. Negative - black wire. Speaker wires have gray, white, and purple shades.

Connection diagram

The connection diagram of the Mystery 818 device is based on an ISO connector, which includes switching points:

• front and rear speakers;
• positive constant signal from the battery;
• antennas;
• negative nutrition;
• positive pulse given when the ignition is turned on.

On the back of the radio, used as a radiator to cool the built-in amplifier, there are 2 linear inputs. The plugs are made of red and white plastic and are used to connect the right and left speakers, respectively. Additionally there is an antenna input.

Setup and operation

When the radio is connected, further setup or operation is not difficult. To turn the device on or off, use the “PWR” button. In order to adjust the sound volume, a rotary control is provided. You need to be careful - it has no travel limiters.

All control buttons are located on the front panel of the radio. For example, you can adjust the equalizer using the “DSP” function. The “SEL” button is needed to adjust the tone of low and high frequencies. It also sets the playback mode - stereo or mono. To select a wave range, press “BND”, and to search for radio stations, press “AMS”.

The “RESET” button allows you to reset the current settings. It is also used to initialize the device after the connection is completed. It is also pressed when the system reboots.

All the necessary information is presented in the user manual, and until the motorist remembers in practice the operation of all the buttons, he will have to look at the instructions often.

You can view information regarding the current status of the device on the LCD display. For example, it displays the radio station that the user is currently listening to, or the name of the song being played. The LED indicator only lights up when the front panel is removed.
