Front panel
Features of the design of the front panel installed in the radio. One device can combine several features at once - for example, the removable panel may well be folding.
—
Removable panel. Possibility to remove the front panel of the car radio and take it with you when leaving the car. The meaning of this function is to protect against theft: firstly, the front panel is the most accessible and attractive part of the radio for thieves; secondly, this reduces the likelihood of the theft of the radio itself, because a device without a control panel is of rather little value.
—
Retractable screen. A retractable screen is usually the preserve of premium radios. When folded, such a screen is hidden in the mounting socket of the radio in a horizontal position, and when working, it moves out and becomes vertical. Thus, with the relatively small dimensions of the radio itself (see Mounting size), it can be equipped with a fairly large screen, allowing you to even watch videos comfortably.
—
Motorized. This feature means that the display of the radio is equipped with a motor drive, due to which you can change the angle of the screen. This function is especially important in light of the fact that in relatively inexpensive types of matrices the image is normally visible only from a certain angle. However, the ability to adjust the tilt of the screen may be usef
...ul in any case.
- Tesla Style. The front panel is made in the style of the on-board computer of Tesla cars. The main feature of this design is a huge touch screen by the standards of a car radio (about 12"), from which you can control not only the radio, but also various functions of the car itself - for example, climate control. Accordingly, such radios have extensive capabilities. They They are usually standard (see “Original radio for”), and are produced not only for Tesla, but also for other car brands.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".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.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.
