Media types

Media types supported by the car radio.

— CDs. Support for optical discs usually assumes at least compatibility with CD, the ability to work with DVD is somewhat less common . For more information about these types, see "Disk Types". Here we note that nowadays, disks are gradually being replaced by more compact and functional media — in particular, memory cards and USB devices; so many modern radio tape recorders, including high-end ones, do not have optical drives at all.

Memory cards. Ability to work with removable memory cards, usually SD or microSD; the module for reading them is called a card reader. This feature is convenient primarily because such cards are supported by many other devices — in particular, laptops and photo / video cameras. The card reader facilitates the exchange of data between these devices: for example, a selection of music from a laptop can be written to a memory card. Note that the specific type of supported cards needs to be specified separately — the (micro)SD format includes several varieties that are not quite compatible with each other.

USB drive (front). The ability of the radio to work with external USB-drives — " flash drives ", hard drives, MP3 players, etc. — to pla...y content directly from them. In this case, it means connecting such media to the USB connector located on the front panel of the radio — it is convenient because the connector is in close proximity, right at hand.

USB drive (rear). Connecting USB drives (see above) through the rear panel. However, the external device is connected not directly to the rear panel, but to an external USB connector, which, in turn, is connected to the rear panel with a cable. Such a connector does not take up space on the front panel, but you can place it on a shelf under the dashboard — and the connected drive will not stick out of the radio, but lie neatly on the shelf. But in standard radios (see above), the “rear” connection can be carried out a little differently — there the cable from the rear panel can be connected to the standard USB socket on the instrument panel using a special connector.

Connecting an iPod/iPhone. The ability to connect portable devices from Apple to the radio — primarily iPods and iPhone smartphones — through a special docking connector. Even the simplest options for such a connection, in addition to playing music, provide a number of additional features — in particular, control of the player's functions (for example, switching a track) from the control panel or remote control of the radio itself. And the most advanced models have a proprietary CarPlay system; for more information about it, see "Control functions".

Android connection. The ability to connect smartphones and other devices based on the Android operating system to the radio. Connection methods may vary: for example, some radio models support only a wired connection, others can use Bluetooth (see "Multimedia"). The same applies to the set of functions available in each case, this point should be clarified according to the manufacturer's official data. Specific features include direct playback of music from the phone (with control through the radio), working with the contents of its drive, watching videos, using the radio as a car kit for receiving calls, etc. And in high-end models, there is support for Android Auto smartphone integration technology; for more information about it, see "Control functions".

Number of fixed settings

The number of fixed settings (presets) provided in the car radio equalizer.

The presence of such settings can greatly simplify the adjustment: choosing the right preset is easier than manually adjusting each EQ band. At the same time, presets are often selected by the manufacturer for certain genres of music and have the appropriate names — "Rock", "Pop", "Jazz", etc.; this simplifies the task even more. And the more fixed settings in the device, the wider the choice of the user. In some radio tape recorders, in addition to pre-flashed ones, user presets are also provided — they can be programmed in advance and turned on in the same way as the preset ones.

Bass Boost function

A function that enhances the bass sound. In some way similar to the equalizer, however, unlike it, when using BassBoost, the bass boost is turned on and off with literally one touch of a button — this is more convenient and safer than fiddling with the equalizer settings.

Volume control

The type of volume control provided in the radio. Rotary knobs, sensors or mechanical buttons are most often used in this role; Here is a more detailed description of each of these options.

— Rotary regulator. The traditional regulator in the form of a round knob, which does not lose popularity nowadays — in fact, it is he who is installed in most modern car radios. Such prevalence, among other things, is due to the fact that the rotary knob is compatible with both digital and analogue volume control circuits — which means that it can be used in devices of any level, from top-end to the most simple and inexpensive. In addition, such a regulator stands out noticeably on the radio panel, so you can even find and turn it by touch, without being distracted once again from the road. The disadvantages of rotary knobs include perhaps some bulkiness compared to buttons and sensors, but this moment is extremely rarely significant.

— Mechanical buttons. Traditional mechanical buttons — more precisely, most often one double-sided rocker button, vertical or horizontal. Unlike the rotary knobs described above, they can only be used with digital volume control circuits; therefore, most radio tape recorders with buttons are advanced devices with extensive functionality and a size of at least 2DIN (or a screen of at least 5 ", for standard models). In such cases, the advant...age of buttons over rotary controls is that the rocker can be made very narrow and install even on a very thin screen frame, while the handle requires a fairly wide additional panel. And if you compare this option with sensors, then mechanical buttons are somewhat cheaper, and you can control them blindly without taking your eyes off the road to the radio panel. On the other hand, the mechanics tend to wear out with use, making it less reliable, and many users simply don't like buttons more than sensors, and for these reasons, and a few others, this option is relatively rare.

— Touch buttons. Controls in the form of sensors that are triggered not by pressing, but by touch. Like mechanical buttons (see above), this control is only compatible with digital volume control and is mainly used in advanced radios with large screens. At the same time, the sensors give the device the most advanced and “technological” appearance, attractive to many users from a purely aesthetic side. The main disadvantage of this option is that the touch buttons usually do not protrude from the panel — so it is almost impossible to find the right sensor blindly, and when controlling the radio, you inevitably have to be distracted from the road. However, with more or less decent driving skills and due care, this moment is not a serious drawback, so this type of control in high-end radio tape recorders is used much more often than traditional buttons.

Control functions

Remote control. The radio has a remote control. This function will be convenient primarily for passengers behind the driver — from the rear seats you can’t reach the radio itself. In addition, remotes often have more keys than the stock control panel, which allows you to access various additional functions on the go without digging through the settings.

Remote control on the steering wheel. Remote control (see above) with the ability to mount on the steering wheel. Such a remote control allows the driver to control the functions of the radio without removing his hands from the steering wheel and thus not being distracted from driving the machine.

Control from regular steering wheel buttons. The ability to control the radio from standard buttons, originally provided on the steering wheel for this very purpose. This function is similar to the steering wheel remote control described above, with the adjustment that the "remote" in this case is built directly into the steering wheel. Before buying such a radio, you must definitely check its compatibility with a particular model of car.

Smartphone control. The presence of software (application) that allows you to control the radio using a smartphone, tablet, etc. This is not just about switching songs on the phone, but a full adjustment of all device functions.
...
Voice control. The ability to control the radio using voice commands. The implementation of such control can be different: in some models, to activate it, you need to press a button, others constantly “listen” to the environment and immediately respond to code words. Anyway, this function allows the driver to control the radio without taking his eyes off the road, which has a positive effect on traffic safety. Note that in its pure form, voice control in modern radio tape recorders is becoming less and less common, being replaced by advanced technologies like CarPlay and Android Auto (see “Control Functions”), which also include voice functions.

Apple CarPlay system. Support for car radio technology CarPlay. This technology is designed to connect portable devices from Apple to the radio, primarily the iPhone, although it is technically possible to work with any “apple” gadget that has iOS 7.1 or later firmware, as well as a proprietary 8-pin Lightning connector. Thanks to this technology, many smartphone functions (including the Siri voice assistant, navigation, call and message management, as well as music) are integrated into the radio; using them through on-board electronics can be much more convenient than holding the iPhone in your hands. At the same time, CarPlay puts special emphasis on safety: it is designed with the maximum use of voice control, so that the driver has to be distracted by the radio screen as little as possible. For example, the mentioned messages can be dictated by voice and listened to "performed" by Siri. The connection itself is carried out by wire, through the mentioned Lightning connector.

Android Auto system. Car radio support for Android Auto technology. Similar to the CarPlay described above, this technology is designed to combine portable devices with on-board electronics of a car — only, as you might guess from the name, in this case we are talking about gadgets running the Android OS. When you connect such a gadget, the radio actually plays the role of an external display for a mobile device, with its optimized interface and related capabilities. Features available through Android Auto include navigation (including mobile device access to external GPS antennas and modules), music control, receiving and making calls, listening to and composing SMS, and searching the Internet. Android Auto is only available for Android 5.0 Lollipop and later; in addition, if the mobile device uses proprietary firmware, its compatibility with the radio needs to be specified separately.

Line out

The number of line outputs (see above) provided in the design of the radio. It should be noted that usually these outputs use RCA connectors (“tulip”), and the analog format allows only one audio channel to be transmitted through one such. Therefore, to work with a stereo signal, two RCA connectors are required, and just a pair of such jacks is considered to be one line output - a set designed for one set of stereo speakers. The main difference between this interface and the same RCA used to connect speakers (see above) is that the line output receives a signal from a preamplifier that is unsuitable for feeding to passive acoustics. Such a signal must be sent to active speakers or an external amplifier (whereas the speaker is connected to the output of a power amplifier designed for passive speakers).

Other inputs

Additional outputs provided in the design of the radio in addition to those described above. These are, usually, rather specific connectors that are rare, for example:

— Control bus input. Input for connecting the control bus — CAN, 5L-Bus, etc. The general idea of the control bus is to combine all the electronics of the car using the simplest single or double wire — instead of complex and bulky multi-wire bundles. Connection to the control bus allows, in particular, to display various data on the radio screen — speed, fuel consumption, tyre pressure, engine temperature, etc.

— Coaxial. Digital input for audio transmission (including multi-channel) through a single connector via an electrical coaxial cable. It is used to connect various advanced audio equipment.

— For the microphone. Input for connecting an external microphone. The microphone itself can be useful, for example, when using the radio as a car kit for a mobile phone, or for voice control. And the input for this accessory in different models can use different types of connectors, this point (as well as additional connection features) should be specified separately.

— For GPS antenna. Input for connecting an external GPS antenna. For more information about GPS navigation itself, see "Multimedia", here we note that an additional antenna provides more reliable reception, improving positioning accuracy and reducing the start time of the GPS receiver after a break in oper...ation.

— For DVD changer. Service connector for connecting a DVD-changer — an external player for several DVD (or CD) discs. The presence of such an input allows not only to play music from the changer, but also to control its settings from the radio: switch between discs, manage playlists, etc. Note that the compatibility of the connector with a specific changer will not hurt to clarify separately.

— For Bluetooth-adapter. Input for connecting an external Bluetooth adapter. For more information about Bluetooth, see "Multimedia", here we note that in some radio tape recorders, instead of the built-in module, this option may be provided. It is convenient in cases where there is no certainty that Bluetooth will be needed in fact: you can buy a radio without overpaying for additional equipment, and purchase an adapter separately if necessary. However, note that the radio, usually, is compatible only with certain models of adapters; the list of compatible accessories in each case must be specified separately.

Backlight

The colour of the backlight plays primarily an aesthetic role, allowing you to choose a radio for the design of the dashboard and user preferences. In addition, some colours have a practical meaning. So, the red backlight is extremely popular nowadays also because it is almost perfect for the dark time of the day: this shade does not knock down "night vision" and has a stimulating effect on the nervous system. And green, on the contrary, relieves excessive nervousness and promotes peace of mind. Other popular colours in modern times include white, blue, orange, yellow, purple ; they do not have such pronounced effects, here the main selection criterion is “like or dislike”.

Also note that in many models several backlight colours are indicated at once. This means that the device has a backlight with adjustable colour selection. At the same time, there are models with a choice of a full range of RGB colours.
